IDataItemListExpanding.CreateAndAddExpanding (METH)ΒΆ
METHOD CreateAndAddExpanding : SysTypes.RTS_IEC_RESULT
Creates a new item for monitoring and immediately adds it to the list similar to IDataItemList.CreateAndAdd. The difference of this method to IDataItemList.CreateAndAdd is that variables of non scalar datatypes (eg. structures or arrays) maybe expanded automatically so that all sub elements are monitored instead of the complete value if that is necessary for a specific type of connected datasource.
- InOut:
- Scope - Name - Type - Comment - Return - CreateAndAddExpanding- SysTypes.RTS_IEC_RESULT- An error code representing the result of the operation. In case of success, ERR_OK will be returned - Input - pstSymbol- POINTER TO STRING - The symbolic name of the variable to activate. Here the name of the variable on the local PLC/HMI is expected.
