Get Analog Tag Alarm Limit
Use the Get Analog Tag Alarm Limit VI to obtain limit information for a single tag value
alarm for an analog tag. Use the Alarm type input (HI_HI, HI, LO, LO_LO) to specify the
desired alarm limit information.
tag name is the name of the tag about whether you want to obtain
information.
alarm type determines the type of alarm for which information is queried.
For analog tags, the various alarm types are HI_HI, HI, LO and LO_LO.
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
Errors
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 specified by alarm
type are enabled. If FALSE, they are disabled. If TRUE, alarm type
alarms are enabled.
limit is the value corresponding to a given alarm type. For example, for
HI_HI alarm, limit is the value the tag must exceed to go to the HI_HI
alarm state.
error out is a cluster that describes the error status after this VI executes.
For more information about this indicator, see the section
Errors Not
Reported by the BridgeVIEW Engine in this appendix.
priority is the priority of the analog alarm being queried. The valid range
is between 1 and 15, where 15 is the highest priority and 1 is the lowest.
