<div class="markdown_content"><p>Hi,</p> <p>is there a way to save the current values of all the variables to a file inside the PLC?</p> <p>I have a system with a Codesys 2.3 PLC and a touchscreen panel, no PC around.<br/> I want, if some unexpected behavior occurs, to dump the internal PLC state to a file stored inside the PLC itself, which I can later upload and examine. This file should contain the current values of all the variables declared in the project in a given moment.<br/> Is there a relatively easy way to do that?</p> <p>I know I can create a POU that can query all the values, but the project is quite big with tons of variables, FB instances etc. Creating such a POU would be a nightmare, so I'm looking for an easier way to do it.</p> <p>Thanks for any suggestions.</p></div>
