Problem with dry stop KBA Rapida 162

Good morning,

I have the following problem: when the machine is in motion, whether it is printing, cleaning or in any other situation, sometimes the machine stops dead, and several errors appear, although normally the first one is usually from BUS CS31. Every time I pass marks the first failure is in a different body, or at the start, or marker. The stop does not always coincide with the first failure in the same place. And when this happens, the connection with Logotronic is lost and the machine has to be restarted. I think it must be a communication or computer problem, but I don't know how to find out and check it since each time the first failure occurs in a different body or area.

I hope you can help me.

Thank you.
