NOT function not working was created by Greshr

The NOT function is not behaving as expected. Despite any changes in the input signal, the output is always false. I am trying to set up an LED to remain lit while the X-axis is moving

The hardware that I am using is a 5i25 card with a 7i25 daughter board and a 7i25 protected breakout. I am using the protected breakout to control some LEDs and a few button inputs and the daughterboard for controlling the CNC.

Code

Code:

###### LED axis Loadrts ######
loadrt comp 
loadrt constant
loadrt hal_parport cfg="0"
loadrt not 

###### LED X Axis ######
setp constant.0.value 0
addf comp.0 servo-thread

net  x-vel-cmd joint.0.vel-cmd => comp.0.in0
net sig-comp-0-input constant.0.out => comp.0.in1
net sig-comp-0-output <= comp.0.equal
net sig-comp-0-output => not.0.in
net sig-not-0-output <= not.0.out
net sig-not-0-output => hm2_5i25.0.gpio.021.out

I think, you don't even need constant.

Code:

setp  comp.0.in1   0

should do it also
