Channel Cross-talk / iParameter Plausibility Check Failed

What does E3-18 mean?

This code indicates two distinct issues: either unintended signal interference between channels within the safety I/O module (cross-talk), or an inconsistency/invalidity in the iParameters during a plausibility check. Both can lead to incorrect signal interpretation or module malfunction, compromising safety.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Restart I/O module, if needed.

2. 4

   If this error persists, replace I/O module.
