Hi,
I've been asked what is involved to upgrade and old CQM1-21 Omron PLC to a CJ2M. I have the old file with an extension of .cdm and searches for the software indicate that CX programmer should open it. If I double click the file project editor with CX Server opens, but whats in there doesn't make any sense. Another file in the machines folder has a .cpt extension, which on my laptop associated itself to Corel Paint. I am assuming this is the HMI program, but again I do not know what software opens it.
Any assistance appreciated.
