TwinSAFE Connection Reset

What does 14 (0x0E) mean?

This error code indicates that a terminal error has triggered a reset of the TwinSAFE Connection. This condition occurs when the 'Error acknowledge active' parameter is set to 'True'. The TwinSAFE communication and associated safety functions will be interrupted and remain in an error state until manually acknowledged, preventing safe operation.

• Previous safety-related fault (e.g., E-stop, safety gate open, safety sensor failure) detected by a TwinSAFE input module, causing the system to go into a safe state.
• Loss of communication or interruption in the TwinSAFE FSoE (Fail Safe over EtherCAT) protocol between the safety controller and the TwinSAFE terminal.
• Mismatch in the TwinSAFE configuration checksum between the safety controller and the physical TwinSAFE terminal, requiring a reset.
• Error in a connected TwinSAFE-compatible device (e.g., safety relay, drive with integrated safety) triggering a system-wide safety reset.
• Internal diagnostic fault within the TwinSAFE terminal itself (e.g., watchdog timer expiry, internal power supply issue) leading to a safety state.

Click steps to track your progress.

1. 1

   1. Access the safety controller diagnostic interface (e.g., TwinCAT Engineering) to review the safety history and identify the specific safety fault (e.g., E-stop, guard switch) that triggered the TwinSAFE connection reset.

2. 2

   2. Verify the physical EtherCAT cabling and connections to the TwinSAFE terminal for integrity. Check link lights for continuous activity and no errors.

3. 3

   3. Compare the TwinSAFE checksum reported by the safety controller with the checksum of the TwinSAFE terminal. If mismatched, download the correct safety configuration to the terminal.

4. 4

   4. Perform a safety function test on all connected safety devices (e.g., E-stops, light curtains, guard interlocks) to ensure they are functioning correctly and not falsely triggering.

5. 5

   5. If the 'Error acknowledge active' parameter (e.g., P9-01) is set to 'True', ensure that the acknowledge command is issued from the safety controller after clearing the underlying safety fault.

6. 6

   6. Replace the TwinSAFE terminal if all external safety circuits and communication links are verified as sound, indicating an internal fault within the terminal.
