Hello Mohammed; For the first part of the question, I suggest you read a few bits of information: 1. an generic explanation od process control with PID loops: PID controller - Wikipedia, the free encyclopedia I suggest you take the time to open and read the links from the Ron Beaufort site, they are very instructive for first-time discoverers of PID loops. There are also many other threads on PID control on the forum, search for them using the Search box at the right of this page. For the second part ofyour question, you must look up FB 41 (or SFB 41) in the online help of Simatic manager, or in the document"System and Standard functions. System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 And on various FAQs you will find on the subject in the forum: Hope this helps, Daniel Chartier |
