Position Moving During WAIT-FOR-RESET

Beckhoff · TwinSAFE Logic FB

What does 0x4024 mean?

The FB CamMonitor entered the WAIT-FOR-RESET state because the Reset input was FALSE, but then the position unexpectedly changed from stopped to moving. This indicates the mechanism moved when it should have been static while awaiting a reset command, posing a risk of unintended motion.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Inspect the position sensor and its input channel (FB instance, Position parameter) for intermittent readings or noise.

  2. 4

    Ensure the process logic correctly sequences the Reset command only when the system is static and safe.
