Posted 17 May 2011 Hi, sometimes my students and I have trouble getting the .cdm file to work. We are linking the point in the symbols list to the CX-serverfile, and it is saved with the project. Then, when we try to open the same .cdm file in the import PLC Points dialogue in CX-Supervisor, we get the message "Could not open cdm file". Somehow the files seem to become corrupt, but there is some content when I look at them in Notepad. Once this has happened, it will not open in CX-programmer either. Sometimes it helps to create a new serverfile in CX-programmer. The filename is in 8.3 format, no special characters. We use CX-one 4.1 and CX-Supervisor V3.0 Educational. Anybody knows what happens to these files, and how we can avoid it? Geir Share this post Link to post Share on other sites
Posted 21 May 2011 Hi Geir, No other comments yet so here's my 2 cents... It sounds like a good plan and I've done similar. I've occasionally had problems too, so started closing CX-Programmer before starting the 'Import' function. For me this seems to work so worth a try... Regards, BB.

Posted 16 May 2014 Have just upgraded to 3.22 Educational and was hoping this cdm import problem had been solved. The few times I have tried the import, part of CX-Supervisor crashed. At the time I was importing a cdm file from one CX-Supervisor project to another. The one successful attempt I renamed the import file to the current project name, started Supervisor again, and was able to import. I still don't know if this was a coincidence or a usable workaround :( Anyway, I had to take the cdm import out of the HMI exercise for my students, too much work when 10 of 15 have problems....
