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 kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by 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 pre-determined for that particular situation. The specified behavior is typically independent of how it is to be 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 is a close analogy between protocols and programming languages: ''protocols are to co ...

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 an objective or practical 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 consen ... 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.

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. 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 Protocol is one of the most popular industrial protocols today. HART protocol has made a good transition protocol for users who wished to use the legacy 4–20 mA signals, but wanted to implement a "smart" protoc ...

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 4-20 mA communication method which requires a separate connection point for each communication device on the controller system. From a business standpoint, FOUNDATION Fieldbus technology delivers savings in total installation costs. H1 Fieldbus reduces instrument wiring, which means less termination and fewer screwdriver turns. The technology reduces hardware requirements and lowers Capital Expenditures (CAPEX). FOUNDATION Fieldbus primarily reduces Operating Expenses (OPEX) through improved plant ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FOUNDATION Fieldbus
Foundation Fieldbus (styled Fieldbus) is an all-digital, serial, two-way communications system that serves as the base-level network in a plant or factory automation environment. It is an open architecture, developed and administered by FieldComm Group. It is targeted for applications using basic and advanced regulatory control, and for much of the discrete control associated with those functions. Foundation Fieldbus technology is mostly used in process industries, but has recently been implemented in powerplants. Two related implementations of Foundation Fieldbus have been introduced to meet different needs within the process automation environment. These two implementations use different physical media and communication speeds. *''Foundation Fieldbus H1'' - Operates at 31.25 kbit/s and is generally used to connect to field devices and host systems. It provides communication and power over standard stranded twisted-pair wiring in both conventional and intrinsic safety applicatio ...

Omron
, styled as OMRON, is a Japanese electronics company based in Kyoto, Japan. Omron was established by in 1933 (as the ''Tateishi 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 Tateishi 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 originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such a .... 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 f ... [...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. Dick Morley is considered as the father of PLC as he had invented the first PLC, the Modicon 084, for General Motors in 1968. PLCs can range from small modular devices with tens of 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. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. PLCs were first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
