Fins Communications Service - Omron CS1W-FLN22 Operation Manual

FINS Communications Service

2-4 FINS Communications Service
22
FINS commands or data can be sent to or received from other manufacturer's
PLCs on the same FL-net network by executing SEND(090), RECV(098), or
CMND(490) instructions in the user's ladder diagram program in the CPU
Unit. This enables control operations such as the reading and writing of I/O
memory between PLCs, mode changes, and file memory operations. (When a
FINS message is sent on an Ethernet network, a UDP/IP header is automati-
cally added to the message.)
The FINS gateway function allows access not only to OMRON PLCs on the
same FL-net network, but also to PLCs on other networks such as SYSMAC
LINK or Controller Link.
