<div class="markdown_content"><p>On any PLC you will only find a compiled version of the program, that is a machinelanguage with only bits and bytes, so a translation back to your written program is impossible.<br/> thus also an upload is impossible, only the old systems like a PS3(moeller) was possible.<br/> If needed more info just give me a call, i am living in shertogenbosch</p></div>

<div class="markdown_content"><p>The upload is only possible when you saved the *.pro to the PLC (can be a Softplc)<br/> You can compare the version in the PLC with the one compiled but it will be different.<br/> Yes version control is very difficult.</p></div>

<div class="markdown_content"><p>I have a Wago 750-842 with a program; stupidly have forgotten which version I have downloaded to it. Doing some experimenting on another -842, I find when opening a program in the PLC I end up with a different program than I know is in there.</p> <p>So I did the Reset PLC Original.<br/> CoDeSys complains there is no program on the controller.<br/> Download the new program. I KNOW what it is.<br/> "Open" New Program &gt; From PLC.</p> <p>I get a different version than the one I just downloaded.</p> <p>Anybody know what gives here?</p></div>
