EPCO: Alternate Alarm Limit Enhancements

Big Picture User Experience

Enterprise is asking for the following enhancements to Alternate Alarm Limits:

  • opening the point's events on a record's control panel should show: changes made to the almlimit, and the almlimitset record that it was is assigned to (otherwise changes to limits can be made affecting the point, but they would not show up in the point's event history)

    • enhancement - must have: when the alarm limit set modifies a point's alarm limits, these changes should show up in the configDataMod summary for the point in question, and indicate the alarm limit set that caused the changes

    • use case: TransGas have analogs have unique alarm limits in winter, but share a common alarm limit set in summer. Customer wants to create a single "summer" alarm limit set, and when it is not active, the points should fall back to using their unique alarm limits. Currently, users should create two alarm limit sets: one for summer and one for winter.

    • enhancement - should have: after an alarm limit set is un-applied, analogs should revert back to their original alarm limits as they were before the alarm limit set was applied

  • enhancement - should have: almlimitset should accept status (it currently only accepts multistate)

    • agreed.

  • enhancement - nice to have: almlimit should be able to accept multiple states (eliminating the need for multiple records)

    • the ability to configure a single alarm limit set that can trigger from multiple states of the trigger point.
