Hi!

I have downloaded sample functionblocks from Siemens, they are know how protected. I want to use four of these function blocks. Problem is that when I insert a FB from the libraries or just copy the one in the project the FB number wont change and I can't change it because it is protected. Any clues?

When you say you want to use "four of these function blocks", do you mean you want to call the same FB four times?

If so, you can simply call it in your code in four different places, and use different parameters and a different instance DB for each call.
