Actually we can do PID control, but we need time proportional control to drivesolidstate relays (on/off) to control heaters in our system. Thank you...

For your application you should study FB58, "TCONT_CP", a continuous control algorithm that allows a pulse duration modulation output for the control of heatingelements (SCRs). Manual on Temperature PID controller FB58: http://support.automation.siemens.com/WW/view/en/18652438 Thread on the forum discussing typical implementation problems of FB58: /tf/WW/en/Posts/19163 Hope this helps, Daniel Chartier
