JamesBUK Posted May 10 Report Share Posted May 10 Hello, Sorry for the simple question. I have created a binary light, red or green, on button and off button on the HMI I want to switch an output on or off either via the button on the HMI or a digital input Using a positive transition contact + a set coil I can turn the light green with the button press, I use a set coil in parallel to turn the output on. Its turned off the same way using a negitoive transition contact and a reset coil. This works. I then try to add the input to control the HMI light and the output. Using just the input I simply use a direct contact and 2 direct coils in parallel this works to turn the light and the output on as long as there is an input present. The problem comes when I put all 3 lines together. I know this must be simple but I cant't get close to finding an answer on google or you tube any help gladly received. Thanks https://drive.google.com/file/d/19vRhSEifG9UlzNCmIZGY_EzArniOiUza/view?usp=share_link Quote Link to comment Share on other sites More sharing options...
