PeterW Member P Join Date Jun 2006 Location Calgary, AB Posts 2,531 Jul 2, 2015 #7 Looking at the manual, section 7 is for controlling. You need to choose a SFB for the control: ● SFB 41 for continuous control (CONT_C) ● SFB 42 for step control (CONT_S) ● SFB 43 for pulse width modulation (PULSEGEN). Read up on this section

It took me a whole 2 minutes to find this: https://support.industry.siemens.co...modulation"-of-the-s7-cpu-31xc?dti=0&lc=en-US
