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 

Not Reported by the BridgeVIEW Engine

 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 

 in this appendix. 

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.
