Q06HCPU Error number 7397 and 3301 PARA ERROR

[Chen Porian 0]

I have Q06HCPU with QJ71E71 Ethernet module. The CPU shows error number 3301 SP. PARA ERROR or 7397 which I cant figure out what it is...

I attached a photo. In addition the Ethernet module does not respond to PING or connection attempts and it is configured well. I am desperate. 

I tried to reset, clear the memory, set all default configurations and more.

If anyone has an idea I would love to hear it. Thanks

Can't really diagnose without looking at the layout of the cards on the rack.  This typically means there are special unit parameters set for a module which is not present, or not present at the location specified in the special unit parameters.

Did you try to format the PLC memory first?
In GXW2: Online, PLC Memory Operation, Format PLC memory

I guess there are still old configuration files on the PLC making reference settings towards special modules
