Serial Gateway Overview
Unifying to FINS Networks for Modbus Slave-compatible Devices
■
Unit Ver. 1.2 or Later
The Board's/Unit's Serial Gateway enables flexible access to OMRON Com-
poWay/F-compatible components from a device on the network (PT or PLC's
CPU Unit). This enables unification of OMRON CompoWay/F-compatible
components with FINS networks.

Pre-Ver. 1.2 Units
Access to Modbus Slave-compatible devices (e.g., OMRON Inverters) from
the PLC using any Modbus command requires execution of the PMCR(260)
instruction in the ladder program of the CPU Unit on the same PLC, incorpo-
rating a communications sequence using the Board/Unit's protocol macro
function. Furthermore, using the protocol macro function prevents access
through the network.
■
Unit Ver. 1.2 or Later
The Board/Unit's Serial Gateway enables flexible access to Modbus Slave-
compatible devices from devices on the network (PLC's CPU Unit and per-
sonal computer). This enables unification of Modbus Slave-compatible
devices with FINS networks.
