Hi to all, S7-1212 DC/DC/DC Is there anybody help me with following problem. Herewith attached is set up for PWM which is not working. What I would like to understand is how this should work from the set up data. If someon have time to make Osciloscope drawing will be nice. I can not see any signal on osciloscope from Q0.2 even I change data from 0-100. Reading manual I still not understand what is timebase ( I know what should be, but Siemens maybe think something else), cycle, thousands! of WHAT? Thanks for any help.
