I need send this data to SCADA by OPC UA. is it possible to convert such UDT to one DWord tags, in process of creation "Server interface" or by SiOME? I tried do it by simple changing data type, when create "Server Interface", and PLC programm was compiled with warning but without error. But OPC Client (UAExpert) could not read this tag. In result i want to reduce number of monitored items whitout changing PLC programm (SCADA can't read/write UDT/Structs). Thank you
