Alarms, Events, and Trends
• Print Trigger: When the tag configured in this field is toggled, the current state of the Alarm/Event Control
object is sent to the default printer.
• PDF Trigger field: When the tag configured in this field is toggled, the current state of the Alarm/Event
Control object is saved as a PDF file at the location specified by PDF Filename.
• PDF Filename field: Enter a complete file path and name where the PDF file is to be saved. You can also enter
a tag name using the {tag} syntax.
Note: PDF Trigger and PDF Filename are not supported in projects running on Windows Embedded or
Thin Client.
• Multiline checkbox: When this option is checked, the print output or PDF will be formatted according to the
available column space, and the text within each cell will be wrapped so that all of it is shown.
• Total items field: Type an integer tag to see how many alarms remain after IWS filters the alarm object using
parameters specified on the Filters dialog.
• Auto Format checkbox: When checked, decimal values in the Display Value, Previous and Value columns will
be formatted according to the virtual table created by the SetDecimalPoints() function.
• Selected tag field: Type a string tag to enable the end user to click on an alarm message to see the name of
the tag associated with that alarm event.
• First Row Text field: Type a string tag. This tag will receive the text of all fields from the first row of the Alarm/
Event Control. The fields are tab delimited. Whenever the first row changes — either due to a new Alarm/
Event, or simply because the rows are reordered — the value of the configured tag is updated.
• Summary Changes field: Type an integer tag. This tag will receive a running count of the number of changes in
the Alarm/Event Control. For example, when a new Alarm occurs or when an Alarm is acknowledged, the
value of the configured tag will be incremented. Reordering the rows is not counted as a change.
• Click the Navigation Triggers button to open the following dialog:
Navigation Triggers dialog
You can make the on-screen Alarm Control object scroll up, scroll down, page up, page down, go to home
(beginning) of page, or go to end of page by configuring tags in the corresponding fields. Whenever the
values of the configred tags change, the Alarm Control object will navigate that way. This is useful for
adding navigation controls to the screen; for example, if you configure the same tag to the Up field in this
dialog and a Pushbutton object, then the Alarm Control object will scroll up whenever the Pushbutton
object is pressed.
When you are finished, click OK to close the Advanced dialog.
Fonts
Click the Fonts button to open a standard Fonts interface where you can specify display properties for the
message text.
Format
Use the Format area of the object properties to configure the appearance of the Alarm/Event Control object
during run time:
