Hello everyone. There were notes about malfunction of PWM duty cycle with S7-1200.
PWM actually works properly with S7-1200 (I used S7-1215C f/w3.0 with TIA 13).
In Device Configuration:
Use “Enable” input to start and stop PWM from your program. Use %QW1000 to instantly adjust duty cycle. IMPORTANT: Please note that setting “Process image” to “None” for Discrete outputs require to use “Tag”:P syntax (add :P after all your discrete output tags). Otherwise your discrete outputs will not function! Please note, that PWM for PID control (e.g. heater element for water temperature controller) is programmed and (perfectly) works, though in very different way.

New question published by Hys is split to a separate thread with the subject Can use pwm with S7-317 2pn/dp?. Best regards |
