Resetting attribute values
The attributes for access rights and initialization time change with REDEF can be reset to their
default values by reprogramming REDEF, followed by the name of the variable or the NC
language command:
● Access rights: Protection level 7
● Initialization time: No initialization or retention of the current value
Redefinable attributes
See "Overview of definable and redefinable attributes (Page 416)".
Local user variables (PUD/LUD)
Redefinitions are not permitted for local user variables (PUD/LUD).
