E-Stop In vs E-Stop Out

I have configure the Mesa 7i76 to connect an external E-Stop IN.
That works.

What about E-StopOUT does it follow the E-Stop Button. When I press ESTOP should I expect to see ESTOP-OUT change State.

What I was trying to do was to Press Estop and Estop-OUT would respond back by activating a relay and also turning ON the light in the ESTOP Button.

Thankyou

Yes and yes.
That is how it is supposed to work.

Heres a recent example with 3 different estop signals I worked out
