Yes, you can use any PyVCP control with a bit output.

Hi, unfortunately i can not link motion out with pyvcp button:
i get this error:
What is wrong with my code?
Thanks.
net machine_up_signal motion.digital-out-00 <= pyvcp.machine-upcustom_postgui.hal:14: Signal 'machine_up_signal' can not add OUT pin 'pyvcp.machine-up', it already has OUT pin 'motion.digital-out-00'What is wrong with my code?
Thanks.

Both motion.digital-out-00 and pyvcp.machine-up are output pins, ie pins that supply a value to be used by other HAL pins, which are inputs.
(I prefer to use "reader" and "writer" sometimes, In this case you have two "writer" pins trying to set the same signal).
motion.digital-out-00 is a HAL pin that writes the result of an M62/M63/M64/M65 command. pyvcp.machine-up is a HAL pin that writes the result of pushing a button to HAL.
What do you actually want to do?

I thought the OP wanted to control a signal from both Gcode and the GUI. Thats what the example I posted achieved.

Thanks for the response.
I have noticed that i was using wrong signal after your warning.
Actually there are two positions up and down. I am trying to move a motor and stop it when it reaches the sensor, there are two sensors and motor moves between these two sensors(up limit sensor and down limit sensor). I am using classic ladder for this purpose, however i can not fully achieve what i need. I appreciate any tip for this kind of purpose.
