I'm currently loosing my mind with the flag and specially with SFCInit
I've tried a lot of things but nothing seems to work :S
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
So what I've tried:
VAR_INPUT
SFCInit:BOOL;
END_VAR
In my SFC POU
but when I'm trying to call it in another POU
I used: PLC_MAIN.Chemical.SFCInit and I received the error message: C0037 Chemical is no Input of PLC_MAIN
I tried too by selecting SFC Init (USE and Delcare one by one and the both) but nothing to do is not working
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)
I've tried too the same thing than in the help of codesys 3, so declaring it as a global variable:
VAR_GLOBAL
SFCinit:Bool;
END_VAR
but it's not working :/
So if someone has an idea of what I could do
Many thanks in advance

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