When the [enter] key is pressed for a valid tag code (ie. Figure 24) the selected tag will be used to
continue the operation for which the selection process was being used if that tag is appropriate for
the operation. For example: if you are performing a parameter modification operation, but have
selected a variable tag code, you will be unable to exit the screen with this variable. The screen
will display this information such as shown in Figure 26. Re-enter a tag code for a parameter or
press [F10] to return to the previous screen without making a selection.

Edit Text

Various operations require a text string to be entered. Operations requiring this are:

- setting external faults,

- adding text to selected Top Level Menu meters,

- identifying the drive with a text string,

- entering a filename.

The terminal's keypad does not contain any alpha keys to allow direct input of the characters.
This section will describe the operation for which characters may be entered.
