Get Bit Array Tag Alarm Setting

Use the Get Bit Array Tag Alarm Setting VI to obtain alarm setting information for bit
array 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

in this appendix.

alarms enabled indicates whether alarms are enabled for this tag. If
TRUE, alarms are enabled for this tag. If FALSE, alarms are disabled.

tag value alarm enabled indicates whether alarms generated by changes
in the value of the tag are enabled. If TRUE, alarms are enabled. If FALSE,
they are disabled.

alarm on ALL indicates how many individual bits must be in alarm before
the entire bit array tag is in alarm. If TRUE, an alarm is generated if all the
bits are in alarm. If FALSE, an alarm is generated if any of the bits in the
bit array tag are in alarm.

invert mask indicates the bits in the bit array tag that must be inverted
before calculating whether the tag is in alarm. invert mask is represented
in hexadecimal.

select mask indicates the bits in the bit array tag to be used for the alarm
calculation.

error out is a cluster that describes the error status after this VI executes.
For more information about this indicator, see the section

priority is the priority of the alarm for a bit array tag. The valid range is
between 1 and 15, where 15 is the highest priority and 1 is the lowest.
