TS Programming System 9-9
The variables contained in the menu tree are fully defined for general PLC
controller tasks. However, in the event that a special task requires a vari-
able that is not provided in the menu tree, such variable can be inserted
as a new variable in the mask that is currently being edited. As a prereq-
uisite, starting from the Main menu with the Variables file menu com-
mand, the new variable must be sufficiently defined (see also Section
8.3.6, "Variables").
Variables are used, for example, to represent an operand status that is
transmitted by the controller to the operator terminal, or simply to display
a text that is assigned to that value. The relationship between the value of
the variable and the display text is indicated in the text list that appears in
the window as a part of the format. The text lists can be edited with the
use of the Edit textlists menu command (see Section 8.3.3.3, "Text
Lists.
9.3.3.1 Help Text
For each mask, a Help text not exceeding the size of the mask can be
entered. Based upon the mask that is currently active, this Help text can
be displayed on the operator terminal by pressing a specific function key.

Fig. 9-13 Help Text For Mask Menu
Selecting the Edit masks menu command displays the menu bar for
mask editing, and the mask to be edited. Selecting the Help text for mask
menu command opens the Help for mask xxx window (where xxx is the
mask number). With the Graphic character command, graphic charac-
ters that are not available on the standard keyboard can be displayed in a
list for subsequent selection and direct insertion into the mask. The last
selected graphic character (displayed in the Editing status window) can
also be inserted at the cursor position by pressing [F8].
