Information

NOTE 1:
Properties dependent on data type are removed if the data type is changed on an existing object model using the Models & Functions tab. This affects the Alarm Configuration, Function, and the applicable instances. The objects must be post-processed to function correctly.
NOTE 2:
A data type on an existing object model is highlighted in red in the Property expander if it is not changed using the Models & Function tab. Save the object model to refresh the instances using the default value of the newly selected data type.
