GROUP Value 1

Function Block Error (Group)

Beckhoff · TwinSAFE Logic FB

What does GROUP Value 1 mean?

At least one TwinSAFE function block (FB) within the EL/EJ69x0 group has entered an ERROR state. This indicates a localized issue within a specific safety function, which then propagates to the group level, causing the entire group to halt safe operation. Investigation of individual FB diagnostics is required.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Address the root cause of the individual FB error (e.g., sensor issue, wiring, parameter misconfiguration, internal logic fault).

  2. 4

    Acknowledge the error at the group level via the 'Err Ack' signal once the underlying issue is completely resolved.
