Redefinition Of System Variables, User Variables, And Nc Language Commands (Redef) - Siemens SINUMERIK 840D sl Programming Manual

1.1.6 Redefinition of system variables, user variables, and NC language commands
(REDEF)
Function
The REDEF command can be used to change system variable, user variable and NC
language command attributes. A fundamental condition of redefinition is that it has to post-
date the corresponding definition.
Multiple attributes cannot be changed simultaneously during redefinition. A separate REDEF
operation has to be programmed for each attribute to be changed.
If two or more concurrent attribute changes are programmed, the last change is always
active.
Redefinable attributes
See "Overview of definable and redefinable attributes (Page 47)".
Local user variables (PUD/LUD)
Redefinitions are not permitted for local user variables (PUD/LUD).
