The Serial Gateway enables flexible access to CompoWay/F-compatible OMRON components on
the network (PT and PLC's CPU Unit).
The Serial Gateway enables flexible access to Modbus-RTU Slave-compatible devices on the net-

The Serial Gateway function can also be executed in the Protocol Macro Mode. (While the Serial Com-
munications Mode is set to Protocol Macro Mode, change the Serial Gateway Prohibit Switches
*_P1_SgwDsblCmd and *_P2_SgwDsblCmd to TRUE to prohibit and to FALSE to enable.)
