How to right sequence run - pause -stop

Hi!
I use external button for START and STOP programm.
To start programm I use the same HAL code:

net strob-auto <= halui.mode.is-auto => not.5.in
net strob-auto-not <= not.5.out

net is-home-x <= halui.joint.0.is-homed => and2.6.in0
net is-home-z <= halui.joint.2.is-homed => and2.6.in1
net is-home-out <= and2.6.out => and2.7.in0
net start-program-btn <= hm2_5i20.0.gpio.032.in_not => and2.7.in1
net start-program <= and2.7.out
net start-program => and2.5.in0
net strob-auto-not => and2.5.in1
#set auto mode
net set-auto <= and2.5.out
net set-auto => halui.mode.auto
#set oneshot impulse length = 2 sec
setp oneshot.1.width 2
#make impulse lenth 2 sec
net set-auto => oneshot.1.in
net start-program-out => oneshot.1.out
net start-program-out => halui.program.run

but to stop the programm, i send pause first, and after thet the stop signal, but error message appears
here is my code:

net is-running <= halui.program.is-running
net is-paused <= halui.program.is-paused
net is-idle <= halui.program.is-idle

net stop-program-btn <= hm2_5i20.0.gpio.033.in_not => and2.8.in0
net is-running => and2.8.in1
net stop-program <= and2.8.out => halui.program.pause
net is-idle => not.6.in
net is-idle-not <= not.6.out => and2.9.in0
net is-paused => and2.9.in1
net is-stop <= and2.9.out => halui.program.stop

What I need to do to stop programm clear?

This is my external Run button


Stop is simpler, simply set halui.program.stop true to stop a program.

A pause/resume button just needs to check the current state of is-paused and is-running.

Not so
I use pyvcp to test.
Here is code example:

net prog-stop <= pyvcp.prog-stop => halui.program.stop

after the press "stop" button the message:
cannot do it
(EMC_TRAJ_SET_TELEOP_ENABLE) in auto mode with stopped interpr..

and the EMC stay in AUTO mode. None key accepted till I press F5 to switch to MDI mode and back to F3 mode.

The solution you sujested not work. What did I wrong?

The problem solved
I assign the time delay 1 sec after the pause and befor the stop pressed

################
# stop program #
################

net is-running <= halui.program.is-running
net is-running => and2.0.in0
net prog-stop-btn <= pyvcp.prog-stop
net prog-stop-btn => and2.0.in1
net set-pause <= and2.0.out => halui.program.pause

setp timedelay.1.on-delay 1
setp timedelay.1.off-delay 0
net strob-pause <= halui.program.is-paused => timedelay.1.in
net prog-stop <= timedelay.1.out => halui.program.stop

Why do you pause then stop?

Because if I send true to hului.program.stop, then the message apeears:

cannot do it
(EMC_TRAJ_SET_TELEOP_ENABLE) in auto mode with stopped interpr..

and the EMC will stop in auto mode!
I have to switch it in manual mode by pressing F5(MDI) then F3(man mode) in AXIS interface.
May be it's EMC internal bug, but I use 2.4.6 version with ubuntu 10.x, in 8.04 is the same problem.
