Module 0: Channel test pulse cross-talk error / Module 2: Channel readback error

What does 13 mean?

This error indicates either a test pulse cross-talk between channels on Module 0 or a readback error on channels of Module 2. Cross-talk implies signals interfering between channels, while readback errors indicate faulty signal verification. Both compromise the isolation and integrity of safety signals, leading to unreliable operation and potential unsafe states.
