Get Discrete Tag Alarm Setting
Use the Get Discrete Tag Alarm Setting VI to obtain alarm setting information for
discrete tags.
tag name is the name of the tag about which you want to obtain
information.
error in (no error) is a cluster that describes the error status before this VI
executes. For more information about this control, see the section
Not Reported by the BridgeVIEW Engine
in this appendix.
alarms enabled indicates whether alarms are enabled for a tag. If TRUE,
tag value alarms as well as bad status alarms are enabled for this tag,
depending on the enable setting for the particular alarm types. If FALSE,
all alarms are disabled for this tag, regardless of the enable settings for the
particular alarm types.
tag value alarm enabled indicates whether alarms generated by changes
in the value of the tag are enabled. If FALSE, they are disabled. If TRUE,
they are enabled.
alarm on low indicates whether an alarm is generated depending on the
discrete tag value. If FALSE, an alarm is generated if the discrete tag value
is high. If TRUE, an alarm is generated if the discrete tag value is low.
priority is the priority of the alarm for a discrete tag. The valid range is
between 1 and 15, where 15 is the highest priority and 1 is the lowest.
error out is a cluster that describes the error status after this VI executes.
For more information about this indicator, see the section
Reported by the BridgeVIEW Engine
in this appendix.
alarm message is the user defined string message displayed along with the
alarm notification.
