Hello kurt; You do not describe what you expect to do in your project, so this might not be exactly what you need. Come back to the thread if you need to give us more information. For heating control using pulsed SCRs we have used FB58 "TCONT_CP", which is a PID function (very similar to standard FB41) associated with a PULSEGEN function that generates a Pulse Duration Modulation signal proportional to the control value output. You wil;l find it described here: http://support.automation.siemens.com/WW/view/en/18652438 Here is a discussion that helps a forum member to make it run: http://support.automation.siemens.com/WW/view/en/20443243 Hope this helps, Daniel Chartier |
