I'm getting this error, it happened on a few PLCs, all of them are CP-2005.
What could cause this error? The TCL2 line is closed with the included resistor and connected in the proper bus structure. IT-1604 module is on the line.
Thank you in advance!

It is an error in the internal peripheral system, the communication between the processor and the internal I/O unit has failed. There is a message from the processor that it could not connect to the unit. I cannot determine the cause, I would try to check and possibly update the firmware of the central unit CP-2005 (the current version is now 6.6) and if the error were to recur even with this fw version, then it would probably be advisable to obtain the debug_info.zip file, which contains available log files. If the central unit restarts automatically after a short time in an error, then at least take a log when you find out that the error occurred. Send it to me at urban(at)tecomat.cz. We will try to look at the logs, maybe something will be seen in them. We would then recommend further steps if necessary.
