Problem when communicating 01 pcs AXC F 2152 and 06 pcs ILC 131 ETH via Profinet
Dear Sirs/Madams,
Now I am using AXC F 2152 (2021.0.2 LTS) as a Profinet controller to connect with 06 device ILC 131 ETH (Profinet device). The problem is the Profinet device (01 or 02 device per case / random) disconnected after 3 working hours and can not reconnect by itself. We have the only choice to reconnect that is restart the ILC 131 ETH.
I sent some more further information in the attachment files, please help me to give some guideline to solve this problem.
Thanks & Best regards;

well it is hard to say what is happening there.
Is the IEC application on the ILC 131 still running?
For some reason processData seem to be invalid.
Please add a Output.log file of the AXC F 2152.
Does the PLC loose connection to all ILC 131 or only to one of them?
Thank you so much for your quick feedback.
The AXC F 2152 only loose connection to 01 or 02 of the ILC 131, but the program inside ILC 131 is still running.
The attachment files is the Output.log, please help me to check. For further information, please see in the below link (AXC F 2152 program, ILC 131 program ...)

If you need any further information, feel free to let me know.
Thanks & Best regards,
for starters you should probably adapt the updaterate of your PN Devices.
There are alot of DHT expires messages => your network or the PLCs can not keep up with your PN refresh rate.
After fixing that we can see if the error still is occuring.
My assumption is that it occumulates until the devices goes into fail.
After changing the PN update rate to 16ms, the system is ok now, thank you so much for your kind support.
Best regards,
