Item
Conversion source FINS command (received via FINS network, Host Link FINS,
peripheral bus, NT links, or CPU bus)
Conversion function Received FINS commands are converted according to the fol-
lowing values before sending to the serial port (peripheral port
or RS-232C port) of the CPU Unit.
2803 hex: Removes FINS header and converts to CompoWay/
F command

Response timeout The time is monitored from when a message converted to
monitoring CompoWay/F protocol using the Serial Gateway is sent until a
response is received (enabled in Serial Gateway mode or pro-
tocol macro mode).
Default: 5 s; Setting range: 0.1 to 25.5 s
Note If a timeout occurs, the FINS end code is returned to the
Send delay None
OMRON Components connected serially to the CPU Unit's RS-232C port or
peripheral port via CompoWay/F can be accessed from the PLC or PT using
CompoWay/F commands enclosed in FINS messages.
• Sent FINS message: FINS header + FINS command code 2803 hex +
