Deactivation Timeout Error

What does GROUP Value 5 mean?

A timeout has elapsed while waiting for a communication error in 'passivate' mode of a manual control unit. This suggests a problem with the deactivation sequence or communication with the manual control unit, potentially preventing the system from entering a safe passive state correctly. The system will remain in an unsafe or error state.

• Communication loss or intermittent connection to the manual control unit (e.g., pendant with safety functions) during deactivation.
• Manual control unit (e.g., HMI with safety buttons) not responding to the 'passivate' command within the configured timeout (e.g., P9-01).
• Faulty wiring or damaged connector (e.g., X201 D-sub) between the safety controller and the manual control unit.
• Incorrect 'Deactivation Timeout' parameter (e.g., P9-01) set too short for the manual control unit's response time.

Click steps to track your progress.

1. 1

   1. Verify the communication link (e.g., EtherCAT, FSoE) to the manual control unit using TwinCAT diagnostics.

2. 2

   2. Check the status and power supply of the manual control unit to ensure it is operational and responsive.

3. 3

   3. Inspect the wiring and connectors (e.g., X201) to the manual control unit for damage, loose connections, or incorrect termination.

4. 4

   4. Adjust the 'Deactivation Timeout' parameter (e.g., P9-01) in the TwinSAFE configuration if the process requires a longer response time.

5. 5

   5. Review the manual control unit's diagnostic messages or internal logs for communication errors.
