Represents an input network variable of type UNVT_alarm. The type cannot be changed. This user-defined network variable type can used to send alarms from 300-series controllers to a 400-series controller to allow it to take some action in the graphical program.
CommError and NvIndex are hidden by default.
The network variable type and associated format can be changed by selecting ‘Change NV Type’ from the SmartTag.
