For the one's who got their hands on with the new KRC5 micro on KSS8.7 and Profinet 6.0 KOP.
The fancy 8 port ethernet switch on the krc5 will be a little tricky.
But for use KLI2 (Port XF5 for PLC Connection - Ethernet/Profinet)
Manual mentions XF6 does the same but does not appear to establish any comms.
Use KSI (Port XF1) for Programming Wov/Debug.
Hope it helps
