Hello Logo! enthusiasts. I made a demo program for a PWM thermostat. It controls the heating using the PWM method. The length of the PWM period is 1 minute (can be set 1 to 15 minutes). The shortest turn-on time is 3 seconds (if the PWM is 5% and the period is 1 minute). Hysteresis is 4 degrees (can be set 1 to 10 degrees). Tested in Siemens LOGO!8 6ED1052-1MD08-0BA1 with firmware 1.83.02 No heating cables, no real sensor, but potentiometer for simulating. Also Web page enabled (2 pages). Andrus 22.07.2023 minor change in program and added working behaviour example. * The .zip file contains the program, work description, diagram and graph (4 files).
