Programming Siemens PLCs is the same like using windows. Pretty comfortable - if you are fine with using it like 85% of the users.
Spent 10h today finding a way to realise an interrupt everytime a specific variable is set.. Every damned microcontroller can be used to! - _-

And therefore this typcial windows user question:
Is it not intended by Siemens or am I blind?

I mean i know you can use some prefabricated interrupts.. Like the cyclic interrupt OB.. I can't believe that it's not provided to freely create interrupts?!

Someone with an idea?
