What does FB TWOHAND Bit 8 mean?

Similar to 'FB TWOHAND Bit 0', but specifically when the 'Safe Inputs after Disc Error' option is active for input pair 1. This means a discrepancy occurred, and although the FB is attempting to maintain a safe state for the inputs, the error persists, indicating a critical issue with the input pair that requires immediate attention and prevents operation.

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

    Perform thorough testing of the two-hand control device and its associated wiring after any repairs or adjustments.
