Thanks a lot for this torrent, hope it still lives! ![]() ![]() These rates are only displayed when locked to a single channel, the AP/client transmission speeds are displayed as part of the clients listed at the bottom. In the Client section, a BSSID of “(not associated)” means that the client is not associated with any AP. Its signification depends on the driver, but as the signal gets higher you get closer to the AP or the station. If the BSSID PWR is - 1, then the driver doesn't support signal level reporting. Each access point sends about ten beacons per second at the lowest rate (1. M), so they can usually be picked up from very far.# Data. Number of captured data packets (if WEP, unique IV count), including data broadcast packets.#/s. Number of data packets per second measure over the last 1. CHChannel number (taken from beacon packets). Note: sometimes packets from other channels are captured even if airodump- ng is not hopping, because of radio interference.

Otherwise, by default, airodump- ng will hop between channels. You might need to be physically closer to the AP to get a quality signal. Make sure you have started your card in monitor mode with airmon- ng (Linux only). Note for madwifi- ng. Make sure there are no other VAPs running. There can be issues when creating a new VAP in monitor mode and there was an existing VAP in managed mode. If it's a ipw. 21. Centrino b), it just can't be helped; go buy a better card. If it's a Prism. 2, try upgrading the firmware. Be sure to stop all connection managers prior to using the aircrack- ng suite. In general, disabling “Wireless” in your network manager should be enough but sometimes you have to stop them completely. It can be done with airmon- ng. Recent linux distributions use upstart; it automatically restarts the network manager. In order to stop it, see the following entry. Deauthenticate an existing wireless client to force it to associate again. Use a tool like mdk. SSID. You can use Wireshark combined with one or more of these filters to review data capture files.

How To Build Trust In Teams Activities Director DutiesI want to thank internal communication experts Keith Burton, Gary Grates and Sean Williams, whose valuable insights and suggestions greatly enriched this article. Definition of the Topic. Employee/organizational communications refer to communications and interactions among employees or members of an organization. I use the terms internal communications and organizational communications to mean the same thing. Internal communications also have been called internal relations (Cutlip, Center & Broom, 2. Kennan & Hazleton, 2. Kreps, 1. 98. 9). Deetz (2. 00. 1) described two ways of seeing and defining internal communications. The most common approach focuses on internal communication as a “phenomenon that exists in organizations” (p. In this view, the organization is a container in which communication occurs. A second approach sees internal communication as “a way to describe and explain organizations” (p. Dawn Becker is Executive Vice President – Managing Director Mixed-Use Division of Federal Realty Investment Trust. In that capacity, Ms. Becker is responsible for. Here, communication is the central process through which employees share information, create relationships, make meaning and “construct” organizational culture and values. This process is a combination of people, messages, meaning, practices and purpose (Shockley- Zalabak, 1. D’Aprix, 1. 99. 6). The first approach has dominated, but the second perspective is gaining wider acceptance as more organizations recognize the crucial role of communication in dealing with complex issues and rapid changes in a turbulent global market. Why Internal Communication Matters. Communication is one of the most dominant and important activities in organizations (Harris & Nelson, 2. Fundamentally, relationships grow out of communication, and the functioning and survival of organizations is based on effective relationships among individuals and groups. In addition, organizational capabilities are developed and enacted through “intensely social and communicative processes” (Jones et al., 2. Communication helps individuals and groups coordinate activities to achieve goals, and it’s vital in socialization, decision- making, problem- solving and change- management processes. Internal communication also provides employees with important information about their jobs, organization, environment and each other. Communication can help motivate, build trust, create shared identity and spur engagement; it provides a way for individuals to express emotions, share hopes and ambitions and celebrate and remember accomplishments. Communication is the basis for individuals and groups to make sense of their organization, what it is and what it means. Communication Processes, Networks and Channels. Internal communication is a complex and dynamic process, but early models focused on a one- way transmission of messages. The Shannon- Weaver Model (1. In this S- M- C- R model, an information source . Later versions of the model added a feedback loop from receiver to sender. Nevertheless, the model suggested that all meaning is contained within the message, and the message would be understood if received. It was a sender- focused model. Berlo’s (1. 96. 0)S- M- C- R model provided a richer interactional perspective. He emphasized relationships between source and receiver and suggested that the more highly developed the communication knowledge and skills of sources and receivers, the more effectively the message would be encoded and decoded. Berlo also acknowledged the importance of the culture in which communication occurs, the attitudes of senders and receivers and strategic channel selection. Later models emphasized the transactional nature of the process and how individuals, groups and organizations construct meaning and purpose (Harris & Nelson, 2. Today, the model is more complex due to new media and high- speed, multi- directional communications (Burton, 2. Williams, 2. 00. 8). However, the core components live on in formal communications planning and implementation. Organizational leaders and communication specialists first develop strategies to achieve objectives, construct relevant messages and then transmit them through diverse channels to stimulate conversations with employees and members. Increasingly, formal communications are grounded in receivers’ needs and concerns. Employees communicate informally with others inside and outside the organization through high- speed communications, too. Communication Levels. Internal communication occurs on multiple levels. Interpersonal or face- to- face (F- T- F) communication between individuals is a primary form of communication, and for years organizations have sought to develop the speaking, writing and presentation skills of leaders, managers and supervisors. Group- level communications occur in teams, units and employee resource or interest groups (ERGs). The focus on this level is information sharing, issue discussion, task coordination, problem solving and consensus building. Organizational- level communications focus on such matters as vision and mission, policies, new initiatives and organizational knowledge and performance. These formal communications often follow a cascade approach where leaders at hierarchical levels communicate with their respective employees, though social media are changing communications at this level. Communication Networks. A network represents how communication flows in an organization. Networks can be formal and informal. In a formal communication network, messages travel through official pathways (e. Informal communications move along unofficial paths (e. Informal communications are often interpersonal and horizontal, and employees believe they are more authentic than formal communications (Burton, 2. Employees and members use both networks to understand and interpret their organizations. Communications also can be described as vertical, horizontal or diagonal. Vertical communication can be downward–flowing down the hierarchy of an organization–or upward, i. Horizontal communication refers to communication among persons who have no hierarchical relationship, such as three supervisors from different functions. Diagonal or omni- directional communication occurs among employees at different levels and in different functions, e. Evolving organizational structures and technologies create opportunities for new and conflicting communication flows (Williams, 2. Studies regarding the effectiveness of communication flows often reveal employee dissatisfaction with both downward and upward communications. Findings by the Opinion Research Corporation, which has examined employee perceptions of internal communication for more than 5. Cutlip, Center & Broom, 2. Less is known about the effectiveness of horizontal and diagonal communications. Communication Channels. A communication channel is a medium through which messages are transmitted and received. Channels are categorized as print, electronic or F- T- F (interpersonal). Common print channels include memos, brochures, newsletters, reports, policy manuals, annual reports and posters. New technologies have spurred the use of electronic channels, e. Intranets, blogs, podcasts, chat rooms, business TV, video conferencing, instant messaging systems, wikis and electronic town- hall meetings. Face- to- face channels include speeches, team meetings, focus groups, brown bag lunches, social events and gatherings and management by wandering around. According to Harris and Nelson (2. Johnson, 1. 99. 6). Effective listening is crucial to learning, understanding, conflict resolution and productive team work. It helps leaders at all levels improve employee morale, retain employees and uncover and resolve problems. Yet, many studies suggest that most people are not good listeners, and few organizations devote resources to developing listening skills in managers and leaders (Alessandra & Hunsaker, 1. The medium is the message.” Marshall Mc. Luhan, 1. 96. 4Today, organizations and their employees and members have access to many communication channels. Selecting the most appropriate medium or media is an important issue for professional communicators once they have determined objectives and strategies, assessed relevant audiences and constructed messages. Perhaps no one made this point more strongly than Mc. Luhan (1. 96. 4), who claimed that “the medium is the message.” He argued that each medium, independent of content, engages receivers in different ways and affects the scale and pace of communication. Mc. Luhan distinguished between “hot” and “cool” media, each of which involves different degrees of receiver participation. Hot media (e. g., print channels, film, lecture, radio) require less active participation and involvement than cool media (e.

Solution. Benefits. Products & Technologies. As users' mailboxes were migrated, the duties of the service management team at Microsoft IT changed from managing an Exchange On- Premises service to managing a hybrid service with Office 3. Exchange Online. The service management team knew a change was needed when surveys produced low net user satisfaction (NSAT) numbers.
Microsoft IT Service Management transitions from Exchange On-Premises to Office 365 Business Case Study. Microsoft IT migrated hundreds of thousands of.After migration to Exchange Online, server tasks belonged to the Office 3. As old duties shifted away from the service management team, others became important, including a broad spectrum of new duties to maximize end- to- end user satisfaction. The service management team acquired a new mind- set and array of tools. It learned about the full spectrum of user and business needs, regularly measured service satisfaction, created ways to let users help themselves, and worked with other teams to address new kinds of issues that surfaced. After making the appropriate focus changes, the NSAT numbers have improved and are even higher than the pre- migration numbers. Office 3. 65 Office 3. Admin Portal.

Solution. While the move to Exchange Online had benefits for. Microsoft IT, the central purpose of the move was to make life better for the. Before migration, the service management team. Exchange email service management from the server side. They had to. acquire a comprehensive end- to- end user point of view. For the service management team, the transition meant. These dimensions include: Usage and experience scenarios. The team profiled individual and business users to understand how they use the email service. For example, the team needed to identify remote users on a poor network connection who need to use Outlook, or a software development team that uses SMTP relays to systematically send email about bugs. Such cases need to be defined in order to plan how to support them. Support for Exchange email services includes Exchange Online Protection, Exchange On Premises and Office 3. Exchange Online, and support of interoperability between other Office 3. Skype for Business and Share. Point. Client applications. Application support includes various flavors of Outlook, different browsers, and Outlook Web App—on a variety of platforms, versions, operating systems, and protocols—including Outlook (RPC or MAPI/HTTP), Exchange Active. Sync (EAS), and Exchange Web Services (EWS). Client devices. Supported devices include personal computers, tablet devices, servers, and mobile devices. Clients must have reliable access over different network and access models, architectures, and infrastructures, including both home and corporate networks and over wireless carrier networks. Multi- platform support includes cross- premises scenarios and identity platforms including Active Directory (AD), Azure Active Directory (AAD), and Active Directory Federation Services.

Office 3. 65, which requires good internet performance. Protocols let applications and devices access Exchange After migration, the service management team had to stay aware. Exchange Web Services (EWS) let client applications communicate with an Exchange server. Applications (including Line- of- Business applications) that communicate by using EWS can send and receive much of the same data that Outlook sends and receives, such as calendar information and email. To send data between Exchange and a client application, EWS uses a framework that consists of Simple Object Access Protocol (SOAP) messages sent over HTTP. Exchange Active Sync (EAS) is a synchronization protocol that lets smartphones and other mobile devices access email, contacts, calendar information, and tasks from an Exchange server. Service managers can set EAS policies such as enforcing encryption or requiring a PIN on the mobile device connected to the Exchange server. RPC or MAPI/HTTP for Outlook clients. Outlook can be configured to use RPC or Messaging Application Programming Interface (MAPI) over HTTPS to access email. Communicate with users. It is important to establish regular. While users need information to help them prepare. The communications cadence. The cadence is a sequence of email messages that Microsoft IT sent to users before and after mailbox migration. The cadence consisted of: All- In. This short, crisp message announced that the mailbox of the recipient would soon be migrated. This message was sent two days before migration. It stated the date of the migration and told how to prepare for migration, connect to services afterwards, and seek technical support if necessary. This message welcomed users to Exchange Online and pointed out what users would find different about the new service. This message was sent to alert users that their migration needed to be delayed. This message was sent if something went wrong. It described the incident and the resolution and reminded users where they could track the status of their Office 3. Exchange Online (Multi- Tenant) service. For more information, see. Migrating Mailboxes to Multi- Tenant Exchange Online in the Related articles section. Knowledge Base sites. The process of supportability improvements, described in the Help Helpdesk succeed section, helps service managers identify current software issues. After an issue is identified, it can be described in a Knowledge Base article, which must be updated as the issue’s status changes. This gives users a central location to find status updates and helps prevent calls to the helpdesk. Perhaps the most important type of communication is the survey process. Surveys tell the service manager how the service is being used and how satisfied users are with it. Microsoft IT provides a general feedback survey that users can fill out at any time. Seven days after migration, they sent a survey about satisfaction with the migration process. Thirty days after migration, users filled out a survey about overall service performance. The surveys are carried out on Share. Point and Access and the survey data is automatically routed into SQL Server databases on Microsoft Azure. Also see the information about the role of communications specialist, in the Have the right team section. Finally, twice a year, a voluntary survey for all IT services is distributed, which Microsoft IT analyzes to find areas of improvement. For example, do users feel they are lacking usability information or do they request that certain features be turned on or off? Validate and enable features. Be aware of automatic feature changes When the service management team moved users. Office 3. 65, certain features were automatically enabled and could not be.

Modbus - Wikipedia. Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1. PLCs). Simple and robust, it has since become a de factostandard communication protocol and is now a commonly available means of connecting industrial electronic devices.
Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Many of the data types are named from its use in driving relays: a single- bit physical output is called a coil, and a single- bit physical input is called a discrete input or a contact. The development and update of Modbus protocols has been managed by the Modbus Organization. There are many variants of Modbus protocols: Modbus RTU — This is used in serial communication and makes use of a compact, binary representation of the data for protocol communication. The RTU format follows the commands/data with a cyclic redundancy check checksum as an error check mechanism to ensure the reliability of data. Modbus RTU is the most common implementation available for Modbus. A Modbus RTU message must be transmitted continuously without inter- character hesitations. Modbus messages are framed (separated) by idle (silent) periods. Modbus ASCII — This is used in serial communication and makes use of ASCII characters for protocol communication. The ASCII format uses a longitudinal redundancy check checksum. Modbus ASCII messages are framed by leading colon (. It uses twisted pair at 1 Mbit/s and includes transformer isolation at each node, which makes it transition/edge- triggered instead of voltage/level- triggered. Special hardware is required to connect Modbus Plus to a computer, typically a card made for the ISA, PCI or PCMCIA bus. Pemex Modbus — This is an extension of standard Modbus with support for historical and flow data. It was designed for the Pemex oil and gas company for use in process control and never gained widespread adoption. Enron Modbus — This is another extension of standard Modbus developed by Enron Corporation with support for 3. Data types are mapped using standard addresses. However the variants are not interoperable, nor are the frame formats. Communication and devices. Each device intended to communicate using Modbus is given a unique address. In serial and MB+ networks, only the node assigned as the Master may initiate a command. On Ethernet, any device can send out a Modbus command, although usually only one master device does so. A Modbus command contains the Modbus address of the device it is intended for (1 to 2. Only the intended device will act on the command, even though other devices might receive it (an exception is specific broadcastable commands sent to node 0, which are acted on but not acknowledged). All Modbus commands contain checksum information, to allow the recipient to detect transmission errors. The basic Modbus commands can instruct an RTU to change the value in one of its registers, control or read an I/O port, and command the device to send back one or more values contained in its registers. There are many modems and gateways that support Modbus, as it is a very simple protocol and often copied. Some of them were specifically designed for this protocol. Different implementations use wireline, wireless communication, such as in the ISM band, and even Short Message Service (SMS) or General Packet Radio Service (GPRS). One of the more common designs of wireless networks makes use of mesh networking. Typical problems that designers have to overcome include high latency and timing issues. Frame format. A Modbus frame is composed of an Application Data Unit (ADU), which encloses a Protocol Data Unit (PDU). For example, 1. 22 (7 . Example: if address, function, and data encode as 2. Two's complement (. Hence the following frame: : F7. A6. 0< CR> < LF>. Modbus TCP frame format (primarily used on Ethernet networks)Name. Length (bytes)Function. Transaction identifier. For synchronization between messages of server and client. Protocol identifier. Modbus/TCPLength field. Number of remaining bytes in this frame. Unit identifier. 1Slave address (2. Function code. 1Function codes as in other variants. Data bytesn. Data as response or commands. Unit identifier is used with Modbus/TCP devices that are composites of several Modbus devices, e. In such case, the unit identifier tells the Slave Address of the device behind the gateway. Natively Modbus/TCP- capable devices usually ignore the Unit Identifier. The byte order for values in Modbus data frames is big- endian (MSB, most significant byte of a value received first). Supported function codes. The various reading, writing and other operations are categorised as follows. A number of sources use alternative terminology, for example Force Single Coil where the standard uses Write Single Coil. This section gives details of data formats of most used function codes. Function code 1 (read coils) and function code 2 (read discrete inputs)Request: Address of first coil/discrete input to read (1. Number of coils/discrete inputs to read (1. Normal response: Number of bytes of coil/discrete input values to follow (8- bit)Coil/discrete input values (8 coils/discrete inputs per byte)Value of each coil/discrete input is binary (0 for off, 1 for on). First requested coil/discrete input is stored as least significant bit of first byte in reply. If number of coils/discrete inputs is not a multiple of 8, most significant bit(s) of last byte will be stuffed with zeros. For example, if eleven coils are requested, two bytes of values are needed. Suppose states of those successive coils are on, off, on, off, off, on, on, on, off, on, on, then the response will be 0. E5 0. 6 in hexadecimal. Function code 5 (force/write single coil)Request: Address of coil (1. Value to force/write: 0 for off and 6. FF0. 0 in hexadecimal) for on. Normal response: same as request. Function code 1. 5 (force/write multiple coils)Request: Address of first coil to force/write (1. Number of coils to force/write (1. Number of bytes of coil values to follow (8- bit)Coil values (8 coil values per byte)Value of each coil is binary (0 for off, 1 for on). First requested coil is stored as least significant bit of first byte in request. If number of coils is not a multiple of 8, most significant bit(s) of last byte should be stuffed with zeros. See example for function codes 1 and 2. Normal response: Address of first coil (1. Function code 4 (read input registers) and function code 3 (read holding registers)Request: Address of first register to read (1. Number of registers to read (1. Normal response: Number of bytes of register values to follow (8- bit)Register values (1. Because the number of bytes for register values is 8- bit wide, only 1. Function code 6 (preset/write single holding register)Request: Address of holding register to preset/write (1. New value of the holding register (1. Normal response: same as request. Function code 1. 6 (preset/write multiple holding registers)Request: Address of first holding register to preset/write (1. Number of holding registers to preset/write (1. Number of bytes of register values to follow (8- bit)New values of holding registers (1. Because register values are 2- bytes wide and only 1.

Illegal Data Value. Value is not accepted by slave. Slave Device Failure. Unrecoverable error occurred while slave was attempting to perform requested action. Acknowledge. Slave has accepted request and is processing it, but a long duration of time is required. This response is returned to prevent a timeout error from occurring in the master. Master can next issue a Poll Program Complete message to determine whether processing is completed. Slave Device Busy. Slave is engaged in processing a long- duration command. Master should retry later. Negative Acknowledge. Slave cannot perform the programming functions. Master should request diagnostic or error information from slave. Memory Parity Error. Slave detected a parity error in memory. Master can retry the request, but service may be required on the slave device. Gateway Path Unavailable. Specialized for Modbus gateways. Indicates a misconfigured gateway. Gateway Target Device Failed to Respond. Specialized for Modbus gateways. Sent when slave fails to respond. Coil, discrete input, input register, holding register numbers and addresses. Some conventions govern how access to Modbus entities (coils, discrete inputs, input registers, holding registers) are referenced. It is important to make a distinction between entity number and entity address: Entity numbers combine entity type and entity location within their description table. Entity address is the starting address, a 1. Modbus frame. As such its range goes from 0 to 6. In the traditional standard, numbers for those entities start with a digit, followed by a number of 4 digits in the range 1–9,9. This translates into addresses between 0 and 9,9. For example, in order to read holding registers starting at number 4. For holding registers starting at number 4. Etc. This limits the number of addresses to 9,9. A de facto referencing extends this to the maximum of 6. This avoids confusion between coils and other entities. For example, to know the difference between holding register #4. JBUS mapping. Another de facto protocol tightly related with Modbus appeared after it and was defined by PLC brand April Automates, resulting of a collaborative effort of French companies Renault Automation and Merlin Gerin et Cie in 1. Modbus TCP/IP Overview. Modbus TCP/IP Unplugged – An introduction to Modbus TCP/IP Addressing, Function Codes and Modbus TCP/IP Networking. OVERVIEWMODBUS TCP/IP is a variant of the MODBUS family of simple, vendor- neutral communication protocols intended for supervision and control of automation equipment. Specifically, it covers the use of MODBUS messaging in an . The most common use of the protocols at this time are for Ethernet attachment of PLC’s, I/O modules, and . Since MODBUS is already widely known, there should be little information in this document which could not be obtained elsewhere. However, an attempt has been made to clarify which functions within MODBUS have value for interoperability of general automation equipment, and which parts are . This was achieved on the simpler variants by an exclusive . A connection is easily recognized at the protocol level, and a single connection may carry multiple independent transactions. In addition, TCP/IP allows a very large number of concurrent connections, so in most cases it is the choice of the initiator whether to reconnect as required or re- use a long- lived connection. Developers familiar with MODBUS may wonder why the connection- oriented TCP/IP protocol is used rather than the datagram- oriented UDP. The main reason is to keep control of an individual . This gives the mechanism a wide tolerance to network performance changes, and allows security features such as firewalls and proxies to be easily added. Similar reasoning was used by the original developers of the World Wide Web when they chose to implement a minimal Web query as a single transaction using TCP/IP on well- known port 8. Data encoding. MODBUS uses a . This means that when a numerical quantity larger than a single byte is transmitted, the MOST significant byte is sent first. So for example: 1. Lwould be. 0x. 12. Interpretation of reference numbers. MODBUS bases its data model on a series of tables which have distinguishing characteristics. The four primary tables areinput discretessingle bit, provided by an I/O system, read- onlyoutput discretessingle bit, alterable by an application program, read- writeinput registers. I/O system, read- onlyoutput registers. The distinction between inputs and outputs, and between bit- addressable and word- addressable data items, do not imply any application behavior. It is perfectly acceptable, and very common, to regard all four tables as overlaying one another, if this is the most natural interpretation on the target machine in question. For each of the primary tables, the protocol allows individual selection of 6. There is no assumption that the data items represent a true contiguous array of data, although that is the interpretation used by most simple PLC’s. The . Today there are no PLC devices which take advantage of that. One potential source of confusion is the relationship between the reference numbers used in MODBUS functions, and the . For historical reasons, user reference numbers were expressed as decimal numbers with a starting offset of 1. However MODBUS uses the more natural software interpretation of an unsigned integer index starting at zero. So a MODBUS message requesting the read of a register at offset 0 would return the value known to the application programmer as found in register 4: 0. Implied length philosophy. All MODBUS requests and responses are designed in such a way that the recipient can verify that a message is complete. For function codes where the request and response are of fixed length, the function code alone is sufficient. For function codes carrying a variable amount of data in the request or response, the data portion will be preceded by a byte count. When MODBUS is carried over TCP/IP, additional length information is carried in the prefix to allow the recipient to recognize message boundaries even if the message had to be split into multiple packets for transmission. The existence of explicit and implicit length rules, and use of a CRC- 3. Ethernet) results in an infinitesimal chance of undetected corruption to a request or response message. Conformance class summary. When defining a new protocol from scratch, it is possible to enforce consistency of numbering and interpretation. MODBUS by its nature is implemented already in many places, and disruption to existing implementations must be avoided. Therefore the existing set of transaction types have been classified into conformance classes where level 0 represents functions which are universally implemented and totally consistent, and level 2 represents useful functions but with some idiosyncrasies. Those functions of the present set which are NOT suitable for interoperability are also identified. It must be noted that future extensions to this standard may define additional function codes to handle situations where the existing de- facto standard is deficient. However, it would be misleading for details of such proposed extensions to appear in this document. It will always be possible to determine if a particular target device supports a particular function code by sending it . Indeed, this is the philosophy which has led to the current function code classification. Class 0. This is the minimum useful set of functions, for both a MASTER and a SLAVE. Class 1read coils (fc 1)read input discretes (fc 2)read input registers (fc 4)write coil (fc 5)write single register (fc 6)read exception status (fc 7)This function typically has a different meaning for each slave family. Class 2. These are the data transfer functions needed for routine operations such as HMI and supervisionforce multiple coils (fc 1. This function has the ability to handle multiple simultaneous requests, and can accept a reference number of 3. Current 5. 84 and 9. PLC’s only use this function to accept references of type 6 (extended register files). This function would be the most appropriate to extend to handle large register spaces and data items which currently lack reference numbers such as . Current 5. 84 and 9. PLC’s only use this function to accept references of type 6 (extended register files). This function would be the most appropriate to extend to handle large register spaces and data items which currently lack reference numbers such as . It is the most efficient way, using MODBUS, to perform a regular exchange of a state image such as with an I/O module. Thus a high performance but versatile data collection device might choose to implement functions 3, 1. FIFO queue (fc 2.

This section describes the general form of encapsulation of a MODBUS request or response when carried on the MODBUS network. It is important to note that the structure of the request and response body, from the function code to the end of the data portion, have EXACTLY the same layout and meaning as in the other MODBUS variants, such as. MODBUS serial port – ASCII encoding. MODBUS serial port – RTU (binary) encoding. MODBUS PLUS network – data path. The only differences in these other cases are the form of any . That is, there is no benefit in sending additional requests on a single connection while a response is outstanding. Devices which wish to obtain high peak transfer rates are instead encouraged to establish multiple TCP/IP connections to the same target However some existing client devices are known to attempt to . Design techniques which allow a server to accommodate this behavior are described in Appendix A. The MODBUS . The request and response are prefixed by six bytes as followsbyte 0: transaction identifier – copied by server – usually 0byte 1: transaction identifier – copied by server – usually 0byte 2: protocol identifier = 0byte 3: protocol identifier = 0byte 4: length field (upper byte) = 0 (since all messages are smaller than 2. The TCP/IP/IP and link layer (eg. Ethernet) checksum mechanisms instead are used to verify accurate delivery of the packet. Protocol reference by conformance class. Note that in the examples, the request and response are listed from the function code byte onwards. As said before, there will be a transport – dependent prefix which in the case of MODBUS comprises the seven bytesref ref 0. The . Simple clients usually choose to leave the values at zero. In the examples, the format for a request and response is given like this (the example is for a .

Kaspersky Internet Security 2010 Setup Movie PreviewsFlame Virus Attacks the Internet. By Dr. Mercola. Big Brother is watching. ![]() Kaspersky Internet Security 2010 Setup Movie WikipediaAnd the warning is coming from none other than Google, which says government spies may be spying on you. Some believe the Google announcement may be related to the recent discovery of the data- mining virus named “Flame.” In a June 3 New York Times article, Andrew Kramer and Nicole Perlroth write. When Eugene Kaspersky, the founder of Europe’s largest antivirus company, discovered the Flame virus that is afflicting computers in Iran and the Middle East, he recognized it as a technologically sophisticated virus that only a government could create. He also recognized that the virus, which he compares to the Stuxnet virus built by programmers employed by the United States and Israel, adds weight to his warnings of the grave dangers posed by governments that manufacture and release viruses on the internet. While the United States and Israel are using the weapons to slow the nuclear bomb- making abilities of Iran, they could also be used to disrupt power grids and financial systems or even wreak havoc with military defenses.” Mr. ![]() Kaspersky claims he was called in to investigate the new virus on behalf of the International Telecommunication Union, an agency of the United Nations. The virus was allegedly erasing files on computers belonging to the Iranian oil ministry. This, clearly, has huge privacy implications were it to be deployed against civilian populations. The module in question.. But researchers also say that the Flame platform pre- dated Stuxnet and its sister, Duqu, and was likely built in the Summer of 2. Information. Week Security recently offered the following advice. Microsoft has been working quickly to patch the certificate bug exploited by Flame. Notably, Microsoft released an update Friday . Security experts are recommending that all users install the update as soon as possible, since attackers will likely attempt to use the certificate vulnerability before it becomes widely patched. Ullrich in a blog post. Patch Tuesday is one of the best dates to launch such an attack, as you do expect patches anyway. According to Wired Magazine: “Under construction by contractors with top- secret clearances, the blandly named Utah Data Center is being built for the National Security Agency. A project of immense secrecy, it is the final piece in a complex puzzle assembled over the past decade. Its purpose: to intercept, decipher, analyze, and store vast swaths of the world’s communications as they zap down from satellites and zip through the underground and undersea cables of international, foreign, and domestic networks. The heavily fortified $2 billion center should be up and running in September 2. Flowing through its servers and routers and stored in near- bottomless databases will be all forms of communication, including the complete contents of private emails, cell phone calls, and Google searches, as well as all sorts of personal data trails—parking receipts, travel itineraries, bookstore purchases, and other digital “pocket litter.” It is, in some measure, the realization of the “total information awareness” program created during the first term of the Bush administration—an effort that was killed by Congress in 2. Americans’ privacy. But “this is more than just a data center,” says one senior intelligence official who until recently was involved with the program. The mammoth Bluffdale center will have another important and far more secret role that until now has gone unrevealed. And code- breaking is crucial, because much of the data that the center will handle—financial information, stock transactions, business deals, foreign military and diplomatic secrets, legal documents, confidential personal communications—will be heavily encrypted. According to another top official also involved with the program, the NSA made an enormous breakthrough several years ago in its ability to cryptanalyze, or break, unfathomably complex encryption systems employed by not only governments around the world but also many average computer users in the US. The upshot, according to this official: “Everybody’s a target; everybody with communication is a target.”. And for those of you still under the mistaken belief that the US government does not have the authority to spy on its citizens, consider the following: “.. The broad outlines of the so- called warrantless- wiretapping program have long been exposed.. In the wake of the program’s exposure, Congress passed the FISA Amendments Act of 2. Telecoms that had agreed to participate in the illegal activity were granted immunity from prosecution and lawsuits. As chief and one of the two cofounders of the agency’s Signals Intelligence Automation Research Center, . He explains that the agency could have installed its tapping gear at the nation’s cable landing stations—the more than two dozen sites on the periphery of the US where fiber- optic cables come ashore. If it had taken that route, the NSA would have been able to limit its eavesdropping to just international communications, which at the time was all that was allowed under US law. Instead it chose to put the wiretapping rooms at key junction points throughout the country.. The network of intercept stations goes far beyond the single room in an AT& T building in San Francisco exposed by a whistle- blower in 2. The eavesdropping on Americans doesn’t stop at the telecom switches. To capture satellite communications in and out of the US, the agency also monitors AT& T’s powerful earth stations.. Binney suggested a system for monitoring people’s communications according to how closely they are connected to an initial target. The further away from the target—say you’re just an acquaintance of a friend of the target—the less the surveillance. But the agency rejected the idea, and, given the massive new storage facility in Utah, Binney suspects that it now simply collects everything..”.

But it’s promised to let you know if it thinks Big Brother is tuned in to what you’re doing. As recently reported on the New York Times’ blog. Gmail inbox, Google home page, or Chrome browser, stating: “Warning: We believe state- sponsored attackers may be attempting to compromise your account or computer.”. According to a Google blog post by Eric Grosse, VP of Security Engineering at Google. If you see this warning it does not necessarily mean that your account has been hijacked. It just means that we believe you may be a target, of phishing or malware for example, and that you should take immediate steps to secure your account. Here are some things you should do immediately: create a unique password that has a good mix of capital and lowercase letters, as well punctuation marks and numbers; enable 2- step verification as additional security; and update your browser, operating system, plugins, and document editors. Attackers often send links to fake sign- in pages to try to steal your password, so be careful about where you sign in to Google and look for https: //accounts.

Unless you’ve been living under a rock this past year, you’ve surely heard about the repeated attempts to restrict your online freedom and grant government near limitless control over the internet and its content. It began in January with the introduction of two proposed laws in US Congress: the Stop Online Piracy Act (SOPA), and the Protect IP Act (PIPA). While “sold” as laws to address online copyright infringement, most of which allegedly arise from outside the US, both laws contained measures capable of severely restricting online freedom of speech and harm web sites and online communities of all kinds, including this one. After tens of millions of people rose up in various protests, both online and by hitting the pavement, both bills were “indefinitely postponed.” Many have warned, however, that the bills are not “dead” and are likely to return. It didn’t take long for the next round. In April, the Cyber Intelligence Sharing and Protection Act (CISPA) was brought forth, and quickly became described by opponents as an even greater threat to internet freedom than SOPA and PIPA. I won’t go into any detailed discussion on these bills here, but simply want to bring your attention to the fact that bills such as these three, while dressed up as laws that will protect you and save you money, are poorly guised attempts to gut privacy laws and open the door for a totalitarian takeover of the internet and its content.

All computers eventually lose that day- one luster, becoming lethargic, unresponsive, and even unreliable. The operating system gets gunked up as apps are added and incompletely deleted, leaving behind drivers and all sorts of other system detritus. Their hard drives fill up with forgotten files we've abandoned in folders whose existence we've forgotten. Programs build up enormous caches behind the scenes that we don't even know about. Eventually, our full hard drives choke the OS as it tries to run. Outdated drivers cease to work correctly. Toolbars and other nasty plug- ins can precipitously slow our browsers to a crawl. It doesn't matter how diligent you are, or what sort of productivity software you use to get the most out of your time if end up sitting around and waiting for your computer to catch up to you. When our machines become so impaired through use and neglect that we can no longer use Microsoft Word or play PC games with the same speed and efficiency to which we have become accustomed, we often ponder buying new computers. But that's a drastic solution, and one that's frequently unnecessary. Instead, you can get often that fresh- out- the- box performance for tens of dollars—instead hundreds or even thousands—thanks to a relatively inexpensive tool: the PC tune- up utility. What's a Tune- Up Utility? A PC tune- up utility is an application that digs deep into your computer and fixes trouble areas. It performs several functions, including defragmenting your PC's hard drive, repairing the incredibly problematic Windows Registry, and freeing up disk space by deleting useless and duplicate files.

TAPS Pro Tactical Augmented Pressure Switch - Programmable. Modular Weapon Command & Control System. Some tune- up utilities perform just those basic functions, while more elaborate ones add numerous features that improve your computer in interesting ways. For example, Iolo System Mechanic—a PCMag Editors' Choice for paid tune- up suites—cleaned our gunked- up test bed with its real- time system monitoring and Commonly Redundant or Unnecessary Decelerators and Destabilizers (CRUDD) Remover. Slim. Ware Utilities Slim. Cleaner Plus troubleshoots your computer's start up process, helping you to remove apps that don't really need to be there that are slowing down your boot time. Sounds pretty good, right? And, thankfully, you won't spend a small fortune to begin the PC clean up process. The subscription- based services can be had for roughly $2. There are even a handful of free tune- up utilities that typically contain less features than their premium counterparts. Starting prices for tune- up utilities typically grant one license per purchase, which means you're allowed to install the software on one PC. That's fine if you own a single computer, but in the age of multi- computer households, the license costs can put a dent in your wallet. To be fair, many companies offer multi- license packages, but they can prove pricey, too. That's why you should look for a paid tune- up utility with no installation limitations, such as Comodo PC Tuneup or AVG Tune. Up. Both let you clean as many computers as you'd like. The other common features found in tune- up utilities include file shredders (for thoroughly deleting hard drive data), scheduling (for setting specific times to run tune- up sessions), and automatic backup (to safeguard your system data from file and system mishaps). Extra Tune- Up Features. The previously mentioned features are par for the tune- up utility course, but a few of the category's top tools contain standout components that aren't commonplace in the space—at least not yet. AVG Tune. Up, for example, offers multi- platform protection with a suite that includes Android, Mac, and Windows tools. Slim. Ware Utilities Slim. Cleaner has Instant Alerts, tools that leverage community recommendations to notify you that unwanted software, such as a toolbar that came packaged with an application, tries to insert itself into the boot process. And Krom. Tech PC Keeper Live has the unique Find & Fix option which is an inbox where Microsoft- certified specialists leave improvement notes after you've run the utility. In addition, many of the utilities automatically fetch new drivers so that your hardware runs at peak performance. If just want that sole feature, check out the Editors' Choice award- winning IObit Driver Booster Pro. It's easy to use, and it's a very useful way to keep your drivers up to date. How I Test Tune- Up Utilities. I test tune- up utilities with a very specific, repeatable process. I run the Geekbench system performance tool and measure boot times on a junked- up testbed before and after running a tune- up utility to compare the computer's potency. I run each test three times and average the results. Each tune- up utility I've tested improved a PC's performance in some fashion. Typically, the operating system feels snappier, and the computer boots up far quicker than it did before I ran the software. Our Recommendations.
