Issue:
Control Expert DTM backward Compatibility .
Product Line:
Control Expert 14.x to higher
Unity Pro 13.x to lower.
Resolution:
DTMs may not be backward compatible. If an application created with Unity Pro/EcoStruxure Control Expert contains DTM version n, do not open and run DTM of version n-1 (or earlier).
DTMs are generally forward compatible. If an application created with Unity Pro/EcoStruxure Control Expert contains DTMs version n, it can be opened and run with DTM version n+1 and above.
As some modules and controller families comes with a DTM (M580 controller, 140CRP312, 140NOC77•, TSXETC101, BMXNOC, BMENOC, 140NOC, HART, PME SW...) this means for example:
-
An M580 application created with Unity Pro V8.1 cannot be built with Unity Pro V8.0.
-
An M340 application with BMXNOC created with Unity Pro V8.1 cannot be built with Unity Pro V8.0.
