Module Diagnostic Active / Prognostics Threshold Reached

What does I xx .DiagnosticActive mean?

This boolean tag indicates that one or more diagnostic conditions are currently active within the module, or a prognostics threshold has been reached. A value of 1 means active diagnostics are present, while 0 indicates no active diagnostics or prognostics thresholds. This suggests an underlying issue requiring further investigation to prevent potential system failure.

• Internal module component operating outside normal parameters
• Communication statistics exceeding predefined thresholds for warnings (prognostics)
• Module detecting a condition that requires attention, but not yet a full fault

Click steps to track your progress.

1. 1

   Consult the Logix Designer application to review specific diagnostic messages or conditions for the module.

2. 2

   Increment the I xx .DiagnosticSequenceCount tag to identify distinct diagnostic conditions.

3. 3

   Check the module's environment for unusual conditions like temperature, vibration, or power fluctuations.
