Create message tags

You can specify message tags for both internal and external processes. These tags include properties to specify an initial message that appears when WindowViewer starts the application and a comment that can be read from the Alarm Viewer.

For more information about defining an I/O message tag, see Specify a message I/O tag.

Define a memory message tag

1. Assign memory message as the type of tag in the Tag Types dialog box.

2. If needed, select Details to show the detail portion of the Tagname Dictionary dialog box.

   

3. Set the properties of a memory message tag. Do the following:

   • In the Maximum Length box, type an integer that is the maximum number of characters that can appear in the tag’s message. Or, accept the default length of 131 characters, which is the maximum message length.

   • In the Initial Value box, type the text of the message that you want assigned to the tag when WindowViewer starts the application.

   • In the Alarm Comment box, type a message that can be read in the AlarmViewer control if the message tag has the Log Events option selected.

4. Save your changes to the tag.
