Communication Protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics (computer science), semantics, and synchronization of communication and possible Error detection and correction, error recovery methods. Protocols may be implemented by Computer hardware, hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be Implementation, implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there ...

HostLink Protocol
HostLink is communication protocol for use with or between PLC's made by Omron. It is an ASCII-based protocol generally used for communication over RS-232 or RS-422. The protocol enables communication between various pieces of equipment in an industrial environment for programming or controlling those pieces of equipment. The maximum allowed message size is 30 words A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its ... per message. Larger messages can be sent by ' fragmentation' process, where the same slave returns a series of messages to build up the entire response. PLC host computers can transfer procedures, and monitor PLC data area, and control the PLC using the HostLink protocol.

HART Protocol
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems. HART is widely used in process and instrumentation systems ranging from small automation applications up to highly sophisticated industrial applications. Based on the OSI model, HART resides at Layer 7, the Application Layer. Layers 3–6 are not used. When sent over 4–20 mA it uses a Bell 202 for layer 1. But it is often converted to RS485 or RS232. According to Emerson,Emerson ''https://web.archive.org/web/20181107104043/https://www.automation.com/automation-news/industry/emerson-proves-advancements-in-eddl-electronic-device-description-language-technology'', rev. 2005-04-14 due to the huge installation base of 4–20 mA systems throughout the world, the HART P ...

Foundation Fieldbus H1
Foundation Fieldbus H1 is one of the FOUNDATION fieldbus protocol versions. Foundation H1 (31.25 kbit/s) is a bi-directional communications protocol used for communications among field devices and to the control system. It utilizes either twisted pair, or fiber media to communicate between multiple nodes (devices) and the controller. The controller requires only one communication point to communicate with up to 32 nodes, this is a significant improvement over the standard 420 mA communication method, which requires a separate connection point for each communication device on the controller system. The Foundation Fieldbus H1 has support for Intrinsically Safe Wiring. Unlike other protocols, FOUNDATION H1 provides explicit synchronization of control and communication for precisely periodic (isochronous) communication and execution of control functions with minimized dead time and jitter. It synchronizes clocks in fieldbus devices for support of Function Block scheduling an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omron
, styled as OMRON, is a Japanese electronics company based in Kyoto, Japan. Omron was established by in 1933 (as the ''Tateisi Electric Manufacturing Company'') and incorporated in 1948. The company originated in an area of Kyoto called ""( ja), from which the name "Omron" was derived. Prior to 1990, the corporation was known as ''Omron Tateisi Electronics''. During the 1980s and early 1990s, the company motto was: "To the machine the work of machines, to man the thrill of further creation". Omron's primary business is the manufacture and sale of automation components, equipment and systems. In the consumer and medical markets, it is known for medical equipment such as digital thermometers, blood pressure monitors and nebulizers. Omron developed the world's first electronic ticket gate, which was named an IEEE Milestone in 2007, and was one of the first manufacturers of automated teller machines (ATM) with magnetic stripe card readers.

Factory Interface Network Service
FINS, Factory Interface Network Service, is a network protocol used by Omron PLCs, over different physical networks like Ethernet, Controller Link, DeviceNet and RS-232C In telecommunications, RS-232 or Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer .... The FINS communications service was developed by Omron to provide a consistent way for PLCs and computers on various networks to communicate. Compatible network types include Ethernet, Host Link, Controller Link, SYSMAC LINK, SYSMAC WAY, and Toolbus. FINS allows communications between nodes up to three network levels. A direct connection between a computer and a PLC via Host Link is not considered a network level. References {{Compsci-stub Network protocols ...

Ethernet Powerlink
Ethernet Powerlink is a real-time protocol for standard Ethernet. It is an open protocol managed by the Ethernet POWERLINK Standardization Group (EPSG). It was introduced by Austrian automation company B&R in 2001. This protocol has nothing to do with power distribution via Ethernet cabling or power over Ethernet (PoE), power line communication, or Bang & Olufsen's PowerLink cable. Overview Ethernet Powerlink expands Ethernet with a mixed polling and timeslicing mechanism. This provides: * Guaranteed transfer of time-critical data in very short isochronic cycles with configurable response time * Time-synchronisation of all nodes in the network with very high precision of sub-microseconds * Transmission of less time-critical data in a reserved asynchronous channel Modern implementations reach cycle-times of under 200 μs and a time-precision (jitter) of less than 1 μs. Standardization Powerlink was standardized by the Ethernet Powerlink Standardization Group (EPSG) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Programmable Logic Controller
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. PLCs can range from small modular devices with tens of Input/output, inputs and outputs (I/O), in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and SCADA systems. They can be designed for many arrangements of digital and analog I/O, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. PLCs were first developed in the automobile manufacturing industry to provide flexible, rugged and easily programmable controllers to replace hard-wired relay logic systems.
