Configures the alarm settings of a shared variable.

You first must enable alarming for a shared variable before you can configure alarm settings. You enable alarming by setting the enable? input in the Configure Alarming (Shared Variable, Enable Alarming) VI to TRUE. You must manually select the polymorphic instance to use.
Note You can configure alarm settings of network-published shared variables only.

Use the pull-down menu to select an instance of this VI.

Inputs/Outputs

  • cgenclassrntag.png variable reference in —

    variable reference in specifies a reference number for a shared variable. Use the Create Shared Variable VI to create a refnum for a shared variable.

  • ccclst.png rate of change alarm settings —

    rate of change alarm settings specifies the rate of change alarm settings of the shared variable.

  • cbool.png enable? (F) —

    enable? specifies whether LabVIEW enables the alarm of the shared variable. The default is FALSE.

  • cstr.png name —

    name specifies the name of the alarm.

  • cdbl.png level/change —

    level/change specifies the change of the rate of change alarm. The alarm change is the value that the shared variable value must change in the specified deadband/time to go into an alarm state. The default is 1.

  • cdbl.png deadband/time —

    deadband/time specifies the time of the rate of change alarm. The time is the amount of time, in milliseconds, in which the shared variable value must change at least the value of level/change to go into an alarm state. The default is 1.

  • cu32.png priority —

    priority specifies the priority of the alarm. Enter a value between 1 and 1000, where 1000 is the highest priority. The default is 1.

  • cenum.png ack type —

    ack type specifies how LabVIEW acknowledges alarms.

  • cstr.png area —

    area specifies the name of the alarm area that this alarm belongs to.

  • cstr.png description —

    description specifies the description of the alarm.

  • cbool.png log? (T) —

    log? specifies whether LabVIEW enables alarm logging for the alarm. The default is TRUE.

  • cbool.png reset when disabled? (F) —

    reset when disabled? specifies whether to reset the value of rate of change alarm settings to the initial state when you disable alarming. If reset when disabled? is TRUE, LabVIEW resets the value. If reset when disabled? is FALSE, LabVIEW retains the value. The default is FALSE.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrntag.png variable reference out —

    variable reference out returns the shared variable refnum that you wire to the variable reference in input.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
