PAC Display Runtime: Discrete alarms trigger only when the tag's value is -1


Applies To:

PAC Display Basic
PAC Display Professional

Versions Affected:

Version affected: R9.5a
Problem is fixed in version: R9.5b

Resolved In Version:

Problem is fixed in version: R9.5b


Symptoms:

Normally, when a discrete alarm is configured as "True/On," Runtime displays an alarm whenever an integer (or integer table element) tag's value is anything other than " 0 " (zero).  However, in the affected version, discrete alarms are triggered only when the tag's value is "  -1  ".

Workaround:

To work around this issue, modify your PAC Control strategy to use a value of  -1 in the tag being used to trigger the alarm.

Resolution:
