Safety Test Output Data Inaccurate or Faulted

What does Testxx.Fault mean?

This boolean tag indicates that the data for a safety test output Testxx is inaccurate and cannot be trusted, or the channel is set to 'Not Used'. A tag value of '1' signifies bad data or a fault. If a short circuit is detected in Pulse Test or Power Supply mode, the output cannot be set to a safe state.

• An underlying hardware fault on the test output (e.g., short circuit, internal module fault, field power loss).
• The test channel Testxx is intentionally set to 'Not Used' in the module configuration.
• A short circuit detected on the test output while it is operating in Pulse Test or Power Supply mode.

Click steps to track your progress.

1. 1

   Access Studio 5000 Logix Designer to view the module's diagnostic information and identify specific active fault conditions related to test channel Testxx (e.g., Testxx.ShortCircuit, Testxx.FieldPowerOff).

2. 2

   Troubleshoot and resolve the specific underlying fault condition identified for test channel Testxx.

3. 3

   Verify the module configuration in Studio 5000 Logix Designer to ensure Testxx is not intentionally set to 'Not Used'.
