Yep, but I don't think I can do a write to an SFC configuration property. Thanks by the way.

Accessing the 'Use' flags directly is not possible, but you can export the POUs to PLCOpenXML and edit the flags there before reimporting.

If your question is about python scripting, then this thread is totally the wrong place 😉

Maybe you want to explain your problem in more detail in the "Engineering" forum.

But just in case, that I got your question right, here is a pointer:
simimar to read_value, you can do a write:

Hi all,
I see this post is so old, but I have a question regarding SFC Configuration flags.
I can create an SFC Pou and, for instance, add SFCInit:BOOL; to the declaration text. But in order to use it, I have to check SFCInit flag from SFC Configuration window.
So, is it possible to configure flags from a python script?

Thanks!

In order to activate SFCInit for a SFC POU you must open the property window of SFC POU object (right button click over the POU name) and in the "SFC Configuration" tab click "Active" in SFCInit variable.

Also the declaration of input variable in the POU is needed:

VAR_INPUT
SFCInit : BOOL ;
END_VAR

I've tried again with the declaration & the validations in the properties but i still have the same message "SFCInit" is no input of mySFC.

What's wrong ? is there a correction in the Patch 2 ?

You have to do both. Check the box for use and declare in element properties and declare the SFC-Flags you want to use as input.

By the way I was wrong My current version is 3.1 SP3 Patch 2 so it is one patch newer than yours.

My version is 3.1 SP3 Patch 1

Did you made just the declaration the use of SFCinit in the SFC properties (and also in the menu Tool\options)

or did you made the declaration explicit of

VAR_INPUT

SFCInit:BOOL;

END_VAR

in the declaration part my SFC POU ?

Regards
