Inputs/Outputs

  • c1dgenclassrntag.png shared variables —

    shared variables is the list of shared variables for which you want alarm status.

    Note If you specify the URL of a target computer, folder, or process for shared variables, the Alarm Status VI returns alarm status for all shared variables on that computer, under that folder or process. To return all alarm status for all shared variables on the localhost, you can specify shared variables as \\localhost. To read alarm status for all shared variables under a process on the computer, you can specify shared variables as \\computer\process.
  • ccclst.png read parameters —

    read parameters is a cluster of options for filtering out alarms.

  • cu32.png Max priority —

    Max priority is the maximum priority of alarms to read. If you do not wire this parameter, this VI reports alarms corresponding to priority level 1,000 and below.

  • cbool.png Show Acknowledged alarms? —

    Show Acknowledged alarms? determines whether this VI reads acknowledged alarms.

  • cerrcodeclst.png error in (no error) —

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

  • icclst.png alarm summary data —

    alarm summary data is the summary of the alarms for the specified shared variables.

  • ii32.png # active alarms occurrences —

    # active alarms occurrences is the number of alarms occurrences currently in the system.

  • ibool.png any alarm occurrences? —

    any alarm occurrences? is an indication of any shared variable in the system being in alarm, regardless of its acknowledgment status. any alarm occurrences? and any shared variables with alarms? return the same information.

  • ii32.png # unack alarms occurrences —

    # unack alarms occurrences is the number of unacknowledged alarms in the system.

  • ibool.png any unack alarm occurrences? —

    any unack alarm occurrences? is an indication of any shared variable in the system being in alarm and unacknowledged. any unack alarm occurrences? and any shared variables with unack alarms? return the same information.

  • ii32.png # shared variables with active alarms —

    # shared variables with active alarms is the number of shared variables with active alarms.

  • ibool.png any shared variables with alarms? —

    any shared variables with alarms? is an indication of shared variables being in alarm. any alarm occurrences? and any shared variables with alarms? return the same information.

  • ii32.png # shared variables with unack alarms —

    # shared variables with unack alarms is the number of shared variables with unacknowledged alarms.

  • ibool.png any shared variables with unack alarms? —

    any shared variables with unack alarms? is an indication of any shared variables with unacknowledged alarms. any unack alarm occurrences? and any shared variables with unack alarms? return the same information.

  • ierrcodeclst.png error out —

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