I am troubleshooting the setup of UDP broadcast receiving on a CP443-1 CP card. The telegrams appear in WireShark with IP 192.168.1.255 Port 7551. As long as the hardware config and NetPro connections are set up accordingly, and regardless of user program, shouldn't the message counters in NCM S7 Diagnostics, Industrial Ethernet Statistics section be counting up?
At the moment it seems only one message comes through, when the communication partner is restarted. I'm guessing this is a special telegram, and it seems the normal telegrams are filtered out by the CP card.
Thoughts?
