Serial Gateway (Converting FINS to CompoWay/F Via Serial Port)

Pre-Ver. 2.0
Unit Ver. 3.0 or Later
Temperature Controllers, Digital Panel Meters, and other CompoWay/F-com-
patible OMRON Components previously could be accessed by sending user-
specified CompoWay/F commands from the PLC. This required, however, the
use of a Serial Communications Board/Unit protocol macro, execution of the
PMCR(260) instruction in the ladder program of the CPU Unit on the same
PLC, and implementation of the standard system protocol (CompoWay/F
Master). The use of protocol macros prevented access across networks.
Note Specific data could be shared without communications instructions if
user-specified CompoWay/F commands were not required, however,
by using the CJ1W-CIF21 Basic Communications Unit.
FINS commands (CompoWay/F commands encapsulated in FINS frames)
received by the CPU Unit at the built-in serial port (RS-232C port or peripheral
port) are converted automatically into CompoWay/F command frames and
transmitted on the serial line. This enables access to CompoWay/F-compati-
ble OMRON components that are connected to the CPU Unit's built-in serial
port via either an NS-series Programmable Terminal (PT) or by using the
CMND(490) instruction.
