OPCItemDef arrays are used in the AddItems method to add items to an OPC group for read/write operations. Instead of creating all the OPCItemDef objects in the program, they can be defined in an XML file. The read method converts the file into an OPCItemDef array that can be directly used in the AddItems method call.
