7i96 estop loop problem

7i96 estop loop problem was created by MarkD2
This is my first time using the MESA 7i96 board. The estop button and screen controls seem to work ok but I am not getting a change on pin 14 with 24 volts on pin 13.
What did I do wrong?

If you have +24V on Pin 13 you have the output polarity of SSR0 backwards
OUT+ goes to the positive voltage source
OUT+ goes to the positive voltage source

I moved the wires but the output is active all the time. What did I miss?

Is the LED for SSR0 on?

I guess I would trace these signals
(the first token after net) with halshow,
starting with estop-out
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_7i96.0.gpio.010.in_not
net estop-out <= estop-latch.0.fault-out
(the first token after net) with halshow,

net estop-loopout iocontrol.0.emc-enable-in <= estop-latch.0.ok-out

How can I invert ssr.00.out.00 as I need to have it active when out of estop.

I would wire it to estop-latch.N.ok-out

I changed net estop-out <= estop-latch.0.fault-out to estop-out <= estop-latch.0.ok-out and now I get an error that estop-latch.0.ok-out is already connected to estop-loopout
Can you send me to the appropriate place in the manual so I can understand how this works?
Thanks for your patients

Then instead change
net estop-out => [HMOT](CARD0).ssr.00.out-00
to
net estop-loopout => [HMOT](CARD0).ssr.00.out-00
There is the manual page for estop_latch, io and iov2 but there does
not seem to be a LinuxCNC guide to setting up Estop.
Skunkworks video is a nice introduction however:

net estop-out => [HMOT](CARD0).ssr.00.out-00
to
net estop-loopout => [HMOT](CARD0).ssr.00.out-00
