<div class="markdown_content"><p>Hi freedumz,</p> <p>I think you set the SFCInit not in a proper way.<br/> Since you Chemical POU is a function block you have to instantiate it:</p> <p>PROGRAM PLC_PRG<br/> VAR<br/> ch1 : Chemical;<br/> bDoInit : BOOL:<br/> END_VAR</p> <p>And now you set SFCInit frow outside using an instance<br/> ch1.SFCInit := bDoInit;<br/> ch1();</p> <p>That should work</p> <p>Regards,<br/> Roman</p></div>

<div class="markdown_content"><p>Hi Everyone,</p> <p>I'm currently loosing my mind with the flag and specially with SFCInit<br/> I've tried a lot of things but nothing seems to work :S<br/> So I'm using SFC(Chemical) like a function block, and I'd like to go back to the init step when I press the reset button<br/> So what I've tried:</p> <p>VAR_INPUT <br/> SFCInit:BOOL; <br/> END_VAR</p> <p>In my SFC POU<br/> but when I'm trying to call it in another POU<br/> I used: PLC_MAIN.Chemical.SFCInit and I received the error message: C0037 Chemical is no Input of PLC_MAIN<br/> I tried too by selecting SFC Init (USE and Delcare one by one and the both) but nothing to do is not working<br/> But when my program is running, in my SFC chemical, I see the flag SFCInit and If I force it, my SFC is reseted (like it has to do)</p> <p>I've tried too the same thing than in the help of codesys 3, so declaring it as a global variable:<br/> VAR_GLOBAL<br/> SFCinit:Bool;<br/> END_VAR</p> <p>but it's not working :/</p> <p>So if someone has an idea of what I could do </p> <p>Many thanks in advance</p></div>
