OMRON components that support CompoWay/F or
Modbus-RTU slave functionality
Note
Note
OMRON components that support CompoWay/F communications or Modbus-
RTU slave functionality (such as Temperature Controllers) can be easily
accessed from a CP1L-EL/EM CPU Unit equipped with an RS-422A/485 or
RS-232C Option Board using Smart Active Parts (SAPs) on an NS-series PT
or using function blocks in the ladder program in the CP1L-EL/EM CPU Unit.
The communications mode in the PLC Setup must be set to the Gateway
Mode to enable this functionality.

RS-232C Option Board
RS-422A/485 (CompoWay/F or Modbus-RTU)
Refer to OMRON's Smart Library website for the most recent information on
using SAPs and function blocks.
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.
Serial ports 1 and 2 on the CP1L-EL/EM CPU Unit can be used to convert to
the following protocols.
• CompoWay/F
• Modbus-RTU
This functionality is enabled when the serial communications mode is set to
Serial Gateway.
