To filter alarm messages during runtime, click the Filters button. The Filters dialog displays so you can specify
filtering parameters for the Alarm Control object.
Filters dialog
• Use the Group field to filter messages by the Alarm group/worksheet number. The worksheets are organized
in the Alarms folder, in the Tasks tab of the Project Explorer, starting with 1. If you specify a Group of 0,
then all of the worksheets will be displayed. You can use commas and/or dashes to specify a range of
groups (e.g.,1,3,5-6).
• Use the Selection field to filter messages by the Selection text configured on the Alarm worksheet.
• In the Priority pane, use the From and To fields to filter messages by the Priority configured on the Alarm
worksheet. Type numerical values into the these fields to delimit the priority range.
• Use the Type field to filter messages by the alarm type (e.g., HiHi, Hi, Lo, LoLo, Rate, Dev+, Dev-). You can
use commas to specify more than one type; for example,HiHi,LoLo.
• Use the State field to filter messages by the alarm status:
Value
Description
0 All alarms (default)
1 All active and unacknowledged alarms
2 All active and acknowledged alarms
3 All inactive and acknowledged alarms
4 All inactive and unacknowledged alarms
Leaving this field blank is effectively the same as entering a value of 0.
• In the Search in columns pane, use the Tagname, Message, and/or Username text fields to specify criteria for
filtering messages. Type a tagname, message, and/or user name into the text field for which you want IWS
to search.
• Use the parameters in the Interval pane to filter messages by the last x messages (Latest) or based on a
period of time (Period). If you do not specify any interval at all, then only the alarms for the current day will
be displayed.
Note:
• You can specify String tags in curly brackets (e.g.{tagname}) in the Group, Selection, Tagname,
Message, and Username fields, to change these values during runtime.
