Is there a simple way to have an on screen popup indicating the external E-Stop was pressed. Something like you get with the axis limits?
If I accidentally bump an external button it would be nice to know it was an external button and perhaps which one.

I know this is an old thread but it helped me get my estop working.
Here is a working config from my system running Master branch 2.8 and a Mesa 7i96 board. My estop button is N/C and is a 24 volt input to GPIO 010 on the Mesa board. Just change the last line for your particular board and GPIO pin.
# ---estop signals---
# create a signal for the estop loopback
#config from BigJohn#
loadrt estop_latch
addf estop-latch.0 servo-thread
net estop-loopout iocontrol.0.emc-enable-in <= estop-latch.0.ok-out
net estop-loopin iocontrol.0.user-enable-out => estop-latch.0.ok-in
net estop-reset iocontrol.0.user-request-enable => estop-latch.0.reset
net remote-estop estop-latch.0.fault-in <= hm2_[HOSTMOT2](BOARD).0.gpio.010.in_not

What GUI are you using. I do have a solution but only for gmoccapy.

Here is my HAL for handling the external estop, this is working correctly.I'm trying to post the mesage like so.
I'm getting this error. With a Mesa 7i76e card how do I make the HAL connection?

I did my best to to try and get a message to post, however I'm stuck. I'm nut understanding the syntax.linuxcnc.org/docs/html/man/man9/message.9.html

Once i had a similar problem, modified and tested this in the sim. Even you got a reply already. This worked for me, and as i have spent time for this, i post it anyway.

I cannot speak to the messaging you asked about but I am working on a system to tell me if the e-stop is the pc (as in startup) a local e-stop (one mounted on the machine) or a remote e-stop. The system simply operates a beacon and the flashing rate of the beacon indicates the trouble spot. It will force the pc into e-stop if local or remote.
If you have any interest please let me know.

Yes, please. Most people here learn better by examples then reading abstract manuals. So I am certainly interested in your system.

Thanks for your interest. I have (hopefully) attached a pdf with a description and photo of the e-stop module. A copy of the schematic is included as well.
If you would like to build one I have boards available as well as the pic micro.
Regards, Dennis
And Happy New Year.

I had to say it. I don't think its necessary to use hardware to achieve what your board does. You could use the sigggen component to flash the lights. Here is an example which i now have running stack lights. The green light flashes and you could apply the same approach to the red light for estop.
