Why can't I upload my IEC program from my Concept PLC?

Published date: 26 November 2019

    IEC code in the PLC not available for upload.

Product Line:
    Concept programming software.

     Either the project was downloaded before Concept 2.5 SR2 which is when IEC upload was added or
     The IEC upload switch was not engaged when the project was originally downloaded.

     There is no workaround for this problem.
     The customer can avoid it in the future by opening the project offline and going to <Project><Code generation options...> and 
        checking <Include IEC upload information>.  This should be followed by a full download to the PLC.
