From me, I have my own test bench , I will set up PRUFIBUS communication from 840D PL to ext. PB Slave , to see the communication is good or not, --and I help customer in the real cases for troubleshooting by this way Siemens (and other companies ) made special devices to scan PB network and connectors, to find bad notes (connectors) or lower signals
