A.7 Behavior when opening the dialog (attribute CB)
The following table provides an overview of the conditions when the CHANGE method is called.
The following applies to attribute CB:
CB0
The CHANGE method is triggered when the screen is displayed if the variable has a valid
value at this time (e.g. through default setting or NC/PLC variable).
CB1 (default)
The CHANGE method is not explicitly triggered when the screen is displayed. If the variable
has a configured NC/PLC variable, then the CHANGE method is of course still called.
