Specifications
6-2
CompoWay/F is an OMRON protocol for general-purpose serial
communications. CompoWay/F features a unified frame format and
FINS-compliant commands, which have a long record of successful
use with OMRON Programmable Controllers. CompoWay/F simplifies
communications between multiple components and between compo-
nents and a computer.
FINS (Factory Interface Network Service)
FINS is a protocol for message communications between Controllers
on an OMRON factory automation network.
Supplement
Communications are implemented by creating a program on the host
computer. The descriptions in this section are therefore from the
perspective of the host computer. For example, "reading" and "writing"
refer to the host computer reading from and writing to the E5AR-T/ER-
T.
