Hi, Here there is some tips about the use of PWM in S7-1200. Sample program: The follow sample program is very simple. There is just the device configuration settings and a CTRL_PWM call. In the watch table, you can modify the digital output, and enable / disable the PWM to see how they works. AttachmentPWM.zip (6010 Downloads) |

Hi, When you change the duty cicle, you don't have more a PWM but a PTO. If your duty cicle is relactivly slow, I suggest you use the PWMof the link /tf/WW/en/Posts/42960#top and adapt it to your necessities. |

why status output value is 16# 80A1 (PWM identifier does not address a valid PWM ).
