E-Stop Discrepancy Error - Group 2 (Safe Inputs Active)

What does FB ESTOP Bit 9 mean?

This fault indicates a discrepancy in E-Stop input group 2, similar to 'FB ESTOP Bit 1', but specifically when the 'Safe Inputs after Disc Error' option is activated. This means that even after a discrepancy, the FB attempts to maintain a safe state for the inputs, but a persistent or critical discrepancy has occurred, preventing normal operation and requiring intervention.
