EStop Out

So I tried the iocontrol pins first.

In my Hal file I have the following lines (not in this order or in the same location):

net estop-in <= parport.0.pin-15-in
net estop-out <= parport.0.pin-14-out
net estop-in <= iocontrol.0.emc-enable-in
net estop-out <= iocontrol.0.user-enable-out

My external e-stop is on pin 15, and my brakes are on the relay on pin 14.

With these lines in my hal file, my external estop controls the estop in axis, and when I click on the estop button in axis, my brakes turn on or off, but the external e-stop still does not operate the brakes. When I try to link pins 14 and 15 or the two iocontrol pins, I get an error message.

does the external estop button when pressed give you the estop warning in Axis ?
in the bottom left corner of axis ..

I am presuming by what you are saying that it works correctly from axis , but not from your hardware estop button input
it may be that your input pin from your estop requires inverting depending on how you have it wired , and it should be a normaly closed switch , and opens when estop button is pressed

As for linking the pins it might be a good time to read this very short chapter on how the net command works.

Please excuse me if my sintax is wrong. I read that earlier, but I copied the format that was already in the Hal file for pin callouts. Would this be more appropriate? (or am I misunderstanding you altogether?) :

net estop-in iocontrol.0.emc-enable-in <=> parport.0.pin-15-in

Yes. The external estop button interfaces with Axis correctly. It is inverted. So on its own, my estop-in circuit works. The estop-out circuit also works on its own, but not with the external estop button.

Thanks

Okay thanks. I don't think I reread my own post before I read your response... I think I understand now. I got sidetracked on another project yesterday, so I'll see what I can do with that info now.

Got it figured out. For some reason I couldn't get it out of my head that the logic had to go through Axis. I was forcing it to take an extra step it didn't want to. I linked my brake pin to the external estop in signal, and it does exactly what I want. Thanks for the help!
