alexmoskos Posted August 25, 2014 Report Share Posted August 25, 2014 Hi, I have a V120-22-R1 connected to an Expansion module that is connected to a IO-D16A3-TO16. I am trying to do PWM through output 0 on the IO-D16A3-TO16 (Source using Pin 8), which is Output 32 in my Visilogic HW configuration. What I am finding is that if my Output is Off but then the frequency Input for it is changed to any number above 0, the physically output turns on and the LED indicator on the module turns on but Visilogic does not recognize that the output is on. What I really I want to do is store a frequency for the output and just turn on the Output bit when I feel like it but if I store a frequency value, the physical output is always on and visilogic doesn't know if it is on or off. I can change the visilogic ladder on and off but there is no physical change to the module output pin, it just stays on. Any idea why this is? What am I missing?
