Iam exporting a DDT from control expert (.XVM format) and importing the same file in vijeo designer v6.2 by using "link variables..." , By this method all the variables are importing in the Vijeo designer variables list, but the tag address are populated as %UV43..... due to this, whenever I re-build my PLC program after modification, the communication error comes in HMI and thus HMI stops communicating with the PLC.
If you check the "HMI variable" checkbox for your variables in Unity/Control Expert they won't get a new internal adress (%UV) when the program is re-built. This is the approach I take if I link the variables.
You should also be able to export your variables as a .txt file. Importing that into vijeo (instead of linking the variable mapping file) should result in all %MW address, I don't remeber how that handles DDTs however...
