With the ctrlX PLC 1.18 version we can import a PLC Open xml file without problems. When we import the same file with the ctrlX PLC 1.20 version we get an error: Object reference not set to an instance of an object. If we remove variables from type POINTER_TO_XXXX in the variable declaration then the PLC Open XML import goes well. It seems that in the ctrlX PLC 1.20 something has been changed regarding PLC Open XML import.
