Low Pass,High Pass,Notch filters in Siemens S7

Hi, I need to use 3 filters in my s7300 PLC. These are Low Pass, High Pass, Notch, but there are in the library of STEP 7. I saw these filters in RSLogix 5000 are present in the library.
How do I do? because I have analog filtering of inputs.
thanks in advance

Hi, and welcome to the forum!

Have you checked out the library from www.oscat.de ?
The libs are written for CoDeSys, PCWorx and Step7.

Lots of useful blocks in there.

I saw the site and I downloaded the library. You were very kind, and I thank you.
