Toggle Flood with One Button

This example shows you how to toggle the flood coolant with a single button. It can be a physical button or a pyvcp button or both if you add and or2 to use either button. In this example I used a pyvcp button.

The image shows the basic connections. It breaks down like this:
If the button is pushed AND the machine is on then input to toggle is on.
When toggle input is on change the output state
When toggle out is on toggle2nist input is on.
When toggle2nist in changes states
If coolant is on output off
If coolant is not on output on

Yes, that was a good catch on that typo. Sometimes you can't see the forest for the trees... or something like that.

Thanks

Not sure that I would use halui.program.is-idle for your power on/off as it is true even if the e-stop is active which means you can't turn the power on in that state. I would use halui.estop.is-activated with a not to invert the state of the pin as part of my and2.
