IC3-MODBUS, how is the TCP version connected.
The modbus device has a TCP interface instead of a RS-232 or a RS-485 interface.
The IC3-Modbus needs only 1 IP connection, this connection serves both the Sigma interface and Modbus interface.
The Modbus TCP device will also need an IP connection and is also connected to the same network.
The Modbus controllers and the Modbus TCP device IP address are mapped at the end of the gateway.txt file.
