Allen-Bradley · Compact 5000 Digital I/O Modules
This diagnostic indicates that the module is operating at a temperature higher than its rated operating limits. This condition can lead to reduced module performance, an 'Uncertain' data quality tag, and potential long-term damage if not addressed. The tag automatically resets to 0 when the condition is removed.
Click steps to track your progress.
Measure the ambient temperature inside the enclosure where the module is installed — verify it is within the module's specified operating temperature range.
Ensure that ventilation openings are clear and any cooling fans or HVAC systems for the enclosure are functioning correctly.
If possible, reduce the load on the module or distribute the load across multiple output points to lessen heat dissipation.
