Offset | Select a number between 0 and the length of the string. This number determines the first character in the string that will be displayed. You can display an entire string, part of it, or display parts of it in different fields. |
Example: Using Offset
You have a string tag that is 12 characters long. The first eight characters contain the tag address and the last four its status. To display only the status, specify a character offset of 8. The address portion of the string will not be displayed. To display the address separately create another string display object. In the Expression field specify the same tag name. Specify a box width of 8 and an offset of 0. This will display the address portion of the string but not the status.
