FB TWOHAND Bit 10

Two-Hand Discrepancy Error - Between Pairs (Safe Inputs Active)

Beckhoff · TwinSAFE Logic FB

What does FB TWOHAND Bit 10 mean?

Similar to 'FB TWOHAND Bit 2', but specifically when the 'Safe Inputs after Disc Error' option is active for the discrepancy between input pairs. This means a timing discrepancy occurred between the two-hand input pairs, and despite the FB's attempt to maintain a safe state, the error persists, indicating a critical violation of the simultaneous actuation requirement, stopping the machine.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Ensure that the logic handling the safe state after discrepancy is correctly implemented and that the underlying input issue is fully resolved and acknowledged.

  2. 4

    Observe the operator's interaction with the two-hand control and make ergonomic adjustments if necessary to facilitate simultaneous actuation.
