Issue
A Vista alarm set up to display a value (such as the temperature being monitored to trigger the alarm) is coming through with question marks where the value should be.
Product Line
TAC Vista
Environment
- Vista Workstation
- Alarm queue
Cause
By default Vista should read the .PV when no other attribute is defined, but sometimes it does not.
Resolution
Add ".PV" to the end of the text string to display the value.
