PAC Display may incorrectly apply the Comm Failure color to table object graphics


Applies To:

PAC Display Runtime Basic
PAC Display Runtime Professional

Versions Affected:

All versions prior to R10.6d

Resolved In Version:

R10.6d


Symptoms:

If any tags on the controller have a Comm Failure quality, PAC Display may incorrectly apply the Comm Failure color to a table object graphic when the Enable graphic color change option is enabled in the Runtime setup.

Workaround:

To prevent the incorrect color change:

  1. In PAC Display Configurator, go to Configure > Runtime. The Runtime Setup dialog appears.
  2. On the Control Engine tab, uncheck the Enable graphic color change option.
The table colors are no longer triggered to change when any other tag attached to that controller has Comm Failure quality codes.

Resolution:
