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.. The FINS communications service was developed by Omron to provide a consistent way for PLCs and computers on various networks to communicate.
HostLink [1] 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.
Omron was established by Kazuma Tateishi (立石一真) in 1933 (as the Tateisi Electric Manufacturing Company) and incorporated in 1948. The company originated in an area of Kyoto called "Omuro (御室) ", from which the name "Omron" was derived. Prior to 1990, the corporation was known as Omron Tateisi Electronics. During the 1980s and early ...
It was derived from IBM's Synchronous Data Link Control protocol, which is the layer 2 protocol for IBM's Systems Network Architecture developed around 1975. ITU used SDLC as a basis to develop LAPF for the Frame Relay environment, along with other equivalents: LAPB for the X.25 protocol stack, LAPM for the V.42 protocol, and LAPD for the ISDN ...
A web portal is a specially designed website that brings information from diverse sources, like emails, online forums and search engines, together in a uniform way. Usually, each information source gets its dedicated area on the page for displaying information (a portlet ); often, the user can configure which ones to display.
Link Access Procedure (LAP) protocols are data link layer protocols for framing and transmitting data across point-to-point links. LAP was originally derived from HDLC (High-Level Data Link Control), but was later updated and renamed LAPB (LAP Balanced). LAPB is the data link protocol for X.25. Other related LAP protocols are: MLP (Multilink ...
Link 11 is a half-duplex, netted link that normally operates by roll call from a data net control station (DNCS). Link 11 can also operate in the broadcast mode. The roll call mode of operation used in the Link 11 interface requires that each participating unit (PU) respond in turn while all other stations are receiving.
Other subroutines can benefit from the use of the link register because it can be saved in a batch with other callee-used registers—e.g. an ARM subroutine pushes registers 4-7 along with the link register, LR, by the single instruction STMDB SP!, {R4-R7, LR} pipelining all memory writes required.
