====== Simatic S7 SCL reference with examples ======
{{ :de:s7:reference.png?120|}} I do not attempt to list __all__ TIA SCL features on this site. To the best of my knowledge, I summarize __important__ and __frequently used__ functions here, I have no time or opportunity for more.

I tried to describe the functions as if I were explaining to a friend how the function works. This may be a bit superficial, but it may be useful. The reference list is constantly expanding and changing.

If you find an error or omission in it, please [[de:impressum|let me know]]!

If you feel that this reference page is helpful, please [[https://www.paypal.com/donate/?hosted_button_id=WGETFWQ9M6C2A|donate it / me]]!
