Hello, Look at What should you watch out for when calling and assigning parameters to the controller functions in function blocks (S)FB41, (S)FB42 and (S)FB43? There you find details about your issue. And of course links for examples using PID FBs. Hope this will helps. Best regards Hristo Mihalev |
