One or More Module Diagnostics Active
Allen-Bradley · Compact 5000 Digital I/O Modules
What does DiagnosticActive mean?
This boolean tag indicates that one or more diagnostic conditions are active or a prognostic threshold has been reached on the module. A tag value of '1' means further investigation is required to identify the specific diagnostic causing the alert on a channel or the module itself.
Common Causes
- Any active fault, warning, or prognostic threshold reached within the module or its individual I/O channels.
- Examples include specific fault conditions like short circuits, overloads, internal module faults, abnormal operating temperatures, or no-load conditions on outputs.
