Code and explanations are available, so you can build on these examples: From the Applications and Tools website (see the link at the top of this page; search on S7-200 motor control): http://support.automation.siemens.com/WW/view/en/20208582/136000&cspltfrm=0&cssw=0&csbinh=0 From the S7-200 tips and Tricks webpage, Regulatory control section: https://www.automation.siemens.com/microset/html_76/support/tipps/tt-steuerungstechnik.htm?HTTPS=REDIR (the two last tips discuss closed-loop wizard and closed-loop positionning). Beware that the S7-200 PLCs are limited in memory and processing speed, compared to higher-level S7 PLCs; precise and accurate positionning at high speed might be frustrating to setup. So first evaluate the degree of precision required for your process before deciding on the level of hardware required.. Hope this helps, Daniel Chartier
