If the touch screen has an Ethernet port, you can create a new modbus slave / tcpip protocol. If the touch screen does not have an Ethernet port, you can go through the serial port and create a new Modbus slave protocol.

The data of the plc protocol is assigned to the newly created variable in the above driver by script assignment.





If you are going to Ethernet, choose modbus slave TCPIP
If you are going to the serial port, choose modbus slave (RTU)




Then the variable table needs to be assigned, establish its own variable table in modbus slave, and then assign the variable passed from the original plc to the variable of modbus slave. The assignment can be assigned periodically by script. The script can be seen in the settings of the actions in the example project below.
