<div class="markdown_content"><p>Dear All,<br/> As titled, may i know how to make PID function works in inverse mode? I would like to make a PID blower control where the set value is wind pressure. In normal mode, blower speed need faster to make higher pressure. But when i select reverse mode, blower speed need slower to make higher pressure. In Tia portal , there is a bit for reverse mode. So i wonder whether reverse mode is available in CoDeSys or not. I had been searched in internet about the method but no result. Hope you all can help me about this. Thank you</p></div>
