Hi,
We use a PLC RFC4072s with connected PROFINET devices. Some of the PROFINET-devices are IO-link masters. If the PLC can connect to the PROFINET-IOL device but the packets are fragmented the IOL-master is not fully configured. If we then move the connection so the packets are intact the PLC can configure the PROFINET-IOL master and it looks ok but one of the cores on the CPU is very high almost 100% all the time. I left it over night but it seems to never go down. If I restart the PLC the load is normal around 30%.
I have tested on FW 2022.0.8 LTS and 2023.0.7 LTS
We have also seen it in 2152.
Is this a known problem?
