“Filter criterion”

For the “Alarm Banner” element only

  • “Most important”: The alarm with the highest priority (lowest value) is displayed.

  • “Newest”: The most recent alarm is displayed.

“Filter by latch 1”

The generated alarms (previous and current) can be filtered by the contents of “Latch variable 1”, which is specified in the configuration of the alarm group. In “Filter type”, you define whether or not the filtering is performed by a string value or a numerical value.

  • “Filter variable”: Indicates what the alarms are filtered by.

    Possible entries:

    • Application variable of data type ‎STRING‎ or ‎WSTRING‎

      Examples: ‎PLC_PRG.strFilterVariable‎, ‎'STRING'‎

    • Directly a literal value

  • “Filter type”: Integer value that determines by which criteria the latch variable value is used for filtering.

    Possible entries:

    • Numeric variable from the application

      Example: ‎PLC_PRG.diFilterType‎

    • Directly a value

      Example: ‎2‎

      Possible values:

“Filter by time range”

The generated alarms (remote, historical, local) can be displayed for a specified time range.

NOTE:

You use the “Filter type” to define whether filtering by time range is enabled or disabled.

  • “Filter variable, from”: Variable of data type ‎DT‎ or ‎DATE_AND_TIME‎ for the start time that the alarms are displayed

    Example: ‎PLC_PRG.filterTimeFrom‎

  • “Filter variable, to”: Variable of data type ‎DT‎ or ‎DATE_AND_TIME‎ for the end time that the alarms are displayed.

    Example: ‎PLC_PRG.filterTimeTo‎

  • “Filter type”: Variable of integer data type that determines whether “Filter by time range” is enabled or disabled

    Possible values:

    • ‎1‎: Filtering is enabled

    • ‎0‎: Filtering is disabled
