When "Modbus RTU Mode" is selected as "Server", ELC.E14 can act as a Modbus RTU Server device to communicate with the Modbus RTU Client device.
After ELC.E14 acts as a Modbus RTU Server device and transmits data to the Modbus RTU Client device, you can configure object mapping information about its data points under "Communication Configuration" > "Server Points". The configuration information in this window also allows ELC.E14 to act as Modbus TCP Server and transmit data to Modbus TCP Client devices.
