Geir Posted January 21, 2018 Report Share Posted January 21, 2018 Hi, I'm new to this and I have questions : I want to send pulses 0-5000Hz , 50% Duty cycle and read them back to my high-speed inputs. I also need something like arrow up/down to control the frecuency and duty cycle. Any ideas ? Regards Geir Quote Link to comment Share on other sites More sharing options...
Cam Posted January 22, 2018 Report Share Posted January 22, 2018 Look at the pwm output in the help file. Frewquncy and duty cycle can be controlled by push buttons you adding on the HMI Quote Link to comment Share on other sites More sharing options...
Geir Posted January 22, 2018 Author Report Share Posted January 22, 2018 Hello again. How can I connect the V200-18-E6B PWM output to High speed input on same module ? Anyone have a drawing ? Regards Geir Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 23, 2018 MVP 2023 Report Share Posted January 23, 2018 What voltage and/or device are the PWM outputs connected to? You've got to pull them up to 24V to run them back into the high speed inputs, which may or may not be possible. Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted January 23, 2018 MVP 2023 Report Share Posted January 23, 2018 Joe, I think he/her/person/carbon entity (oh gosh I hate PC getting so silly of late) is essentially wanting to loop the plc outputs back to the inputs. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 23, 2018 MVP 2023 Report Share Posted January 23, 2018 I found this on the web- +V is 24 VDC Resistive load is 2.2 K. Output pulse goes to I0 Sensor output is the npn HSO on the -E6 I'll leave the rest of the connection details to you as an exercise. This will work in stand alone mode. If you connect something else to the "Output Pulse" without disconnecting the PLC input it probably won't work as impedance matching of two parallel devices with different threshold voltage levels is damn hard.

Geir Posted February 22, 2018 Author Report Share Posted February 22, 2018 Hello. I got the high speed in and outputs to work and they are connected. What I see now is the following : When I set up the PWM with value 500 on frequency and value 500 on duty cycle, it shows on the oscilloscope 50 Hz as it should (IMG_0878.JPG). But, when I change the time measurement on the oscilloscope to 1 sec per div, I get the following picture (IMG_0879.JPG) Can anyone try to explain this please ?
