Serial Gateway Function
When a FINS command is received, it is automatically converted to the proto-
col corresponding to the message and sent on the serial communications
path. Responses are also converted in the same way.
Note
Serial ports 1 and 2 on the CP1L CPU Unit can be used to convert to the fol-
lowing protocols.
• CompoWay/F
• Modbus-RTU
This functionality is enabled when the serial communications mode is set to
Serial Gateway.
