3.1.7 Configuring the Process Data Channel

The process data channel serves for the communication between the Coupler

and the higher ranking systems (Master or project and diagnostics PC).

This channel is allocated to the Coupler and can not be used. When designing

the node, this position should therefore always show “750-343 No process

data channel”.
