EcoStructure Control Expert v15.3 Does not Compile Libset v13.0 and earlier

[Rick2]

Literally the title. I just want a simple answer to this situation and support wont answer it.

I have a program written in EcoStructure Control Expert v15.3 for an m340 v3.3. 

I want to build the program so that it is compatible with libset v13.0. This is simple for every other libset version. The compiler has no issues until I downgrade to v13.0 and earlier. All of these libsets throw a Linker error during compile time. 

In order to force the libset to compile I must delete all logic programs. Then the program compiles with all of my auxilary stuff, DTMs, drives, NOC, IO, etc. 

It seems the compiler is missing a referenced library for these earlier libset versions.

I have used new ECE to open very old programs with old libsets without issue, but I have never tried to downgrade the libset before.  I know you can choose to upgrade the libset, so why not downgrade it via the same method?

You could try this:

From the Start menu > Ecostruxure Control Expert > 'Libset Installer' and check that libset v13 is installed.

Then open ECE, and File > Open, and navigate to your file, but don't open it yet.

Select the file, then down the bottom select "Select a specific target version", and choose v13.0 from the drop down.

I just did a test run on an M340 program, and successfully downgraded and built a v14.0 libset program to libset v13.0.

Hello 

I had a similar case and we solved it by exporting it to a ZEF file and importing it in again. Sometime the files get corrupted.
