Initialization value: STRING data type
In the case of variables of the
quotation marks, e.g. ...= "MACHINE_1"
Initialization value: AXIS data type
In the case of variables of the
identifier must be enclosed in brackets, e.g. ...=(X3).
Initialization value: System variable
For system variables, redefinition cannot be used to define user-specific initialization values.
The initialization values for the system variables are specified by the system and cannot be
changed. However, redefinition can be used to change the point in time (
which the system variable is reinitialized.
Implicit initialization value: AXIS data type
For variables of the
● System data: "First geometry axis"
● Synchronized action GUD (Designation: SYG_A*), PUD, LUD:
Implicit initialization value: Tool and magazine data
Initialization values for tool and magazine data can be defined using the following machine
data: MD17520 $MN_TOOL_DEFAULT_DATA_MASK
NOTICE
Synchronization
The synchronization of events triggering the reinitialization of a global variable when this
variable is read in a different location is the sole responsibility of the user/machine
manufacturer.
