The GUD variable is not displayed on the operator panel.
Note
The new GUD variable, which is already being displayed, will be detected by the RESU function
and supplied with an up-to-date value only following an NCK POWER ON Reset. Hence, a
NCK POWER-ON must be initiated after the creation.
References
The exact procedure to be following while creating and displaying GUD variables depends on
the software version of the existing operator panel and is described in the:

Continue machining within subprograms

Subprogram call outside or inside a program loop
Clear retrace support within subprograms depends on whether the subprogram call is made
outside or inside a program loop:
● Outside
Clear retrace support is possible if a subprogram is called outside a program loop.
● Inside
Clear retrace support may not be possible if a subprogram is called inside a program loop
(see Section "Continue machining within program loops (Page 724)").
Number of passes P
Subprogram repetitions using number of passes P are taken into account for retrace support.
This means that retrace support is performed in the part program with the correct reference to
the part program block and number of passes P to the program continuation point of the contour.
