Hi, I'm trying to make a button that has 4 images that is selected from the PLC and a bool written to the PLC to tell it if the button is pressed or not. I know that a normal button can't do this, so I am playing around with the "Combined element". I can make the images change depending on a value, but I can't figure out how to send the pressed state to the PLC. The variable in the "variable/function" box is used to select the states. I see that there is a "Write Set value" section, but I don't see where I can enter a second variable. Do I need to put a button behind the combined element?
Thanks,
Denis.
