Muting Sequence Violation
Beckhoff · TwinSAFE Logic FB
What does FB MUTING Bit 6 mean?
The programmed muting sequence has been violated. This occurs if muting sensors are activated in an incorrect order or at incorrect times, or if an object remains in the detection zone for too long during muting. This is a critical safety fault, as it implies an attempt to bypass the safety function improperly or unintentionally, causing an immediate safety stop.
Complete Troubleshooting Guide
- 1
Observe the process to identify the exact cause of the sequence violation (e.g., object passing through muting zone incorrectly, operator error).
- 2
Review the muting sensor positions, alignment, and configuration in the TwinSAFE project to ensure they match the application's requirements.
- 3
Check the 'MuteMode' parameter and other timing/sequence parameters in the FB MUTING configuration for correct values.
- 4
Verify the functionality and reliable detection of the muting sensors themselves.
