4.2 Data exchange via Modbus/TCP
4 Application example
In this program, inputs on the PNOZmulti are copied to virtual outputs.
The PSSu system reads the data from the PNOZmulti, processes it and
then writes it back to the virtual inputs on the PNOZmulti. There the state
of the virtual inputs is written to signal outputs.
