Hello everyone,
In 2017, three KUKA KRC4 robots for the transport of aluminum rims were installed in our plant.
Last year, errors KSS13008, KSS13016, KSS13020 started to appear on all three robots. After contacting KUKA support I was told to replace all the cables inside the KUKA electrical cabinet, KPP and KSP modules (it was pointless for me to change the modules as the error rarely occurred).
We haven't had any problems with the errors above for the past 10 months, but the errors have started to recur in the past month.
In attachments are three images with errors that occur on three different robots. All robots are on the same network, and they are connected to the main PLC controller via Ethernet switches (Scalance - Profinet).
The figure in attachment also shows the network topology for the part of the plant where the problem occurs.
I hope someone can help me.
