Why I am unable to upload Momentum plc program using Concept.
To obtain a complete project when uploading from the PLC, In Concept Options Include IEC Upload Information must be activated in the dialog box
at the time of downloading the program to the plc. If this check box is not activated only the executable code (machine code) is loaded onto the PLC.
If at the time of initial download this option was not checked, you won't be able to upload the complete project (for eg. iec sections)
