General conditions
Initialization value: Global user variables (GUD)
• Only INIPO (POWER ON) can be defined as the initialization time for global user
variables (GUD) with the NCK range of validity.
• In addition to INIPO (POWER ON), INIRE (reset) or INICF (NewConfig) can be defined
as the initialization time for global user variables (GUD) with the CHAN range of validity.
• In the case of global user variables (GUD) with the CHAN range of validity and INIRE
(reset) or INICF (NewConfig) initialization time, for an NC reset, mode group reset and
NewConfig, the variables are only reinitialized in the channels in which the named events
were triggered.
Initialization value: FRAME data type
It is not permitted to specify an initialization value for variables of the FRAME data type.
Variables of the FRAME data type are initialized implicitly and always with the default frame.
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: STRING data type
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.
