Work preparation

3.1 Flexible NC programming

Initialization value: CHAR data type

For variables of the CHAR data type, instead of the ASCII code (0...255), the corresponding

ASCII character can be programmed in quotation marks, e.g. "A".

Initialization value: Data type STRING

In the case of variables of the STRING data type, the character string must be enclosed in

quotation marks, e.g. ...= "MACHINE_1"

Initialization value: AXIS data type

In the case of variables of the AXIS data type, for an extended address notation, the axis

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 (INIRE, INICF) at

which the system variable is reinitialized.

Implicit initialization value: AXIS data type

For variables of the AXIS data type the following implicit initialization value is used:

● System data: "First geometry axis"

● Synchronized action GUD (designation: SYG_A*), PUD, LUD:

axis designation from the machine data: MD20082

$MC_AXCONF_CHANAX_DEFAULT_NAME

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

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.
