Type a number between 1 and 82 to specify the length of the
string tag in bytes. The length must be a multiple of 2. Tags using
References 0 and 1 must align on word boundaries.
Initial Value
Enter an initial value for the tag. When a tag is used with a

controller, you must choose No for “Use Default Operation,” on
the terminal’s Application Startup screen, and you must cycle
power to the terminal. Default values are written to the controller
whenever you subsequently cycle power to the terminal.

application.
