No matter whether ELC.E14 is Modbus RTU ModeClient or Server, it can act as Modbus TCP Server to transmit data to Modbus TCP Client. You can configure mapping information about data points under "Communication Configuration" > "Server Points“ ("TCP & COM1 Server Points” or “TCP Server Points”). The configuration information in this window also allows ELC.E14 to act as Modbus RTU Server and transmit data to Modbus RTU Client devices.
You can use Modbus Poll or ModScan tools (Modbus TCP Client) on the same computer to perform Modbus TCP debugging with the controller's simulator (Modbus TCP server). You can also use the configuration software (Modbus TCP Client) directly for debugging.
