Andy would win hands down. (he wrote the hardware interface driver for my first Linuxcnc machine, and helped walk me through setting it up.)
All I'm good for is the occasional bit of hal setup or ladder logic. A programmer I am not.

If anyone is following this thread I did it in HAL, it was actually quite easy, here's the config:
Put this in your main hal file
Then in your post_gui (as you'll need some of the pins that load).
Note that pdnt pins are for my pendant the general lines are above but commented out:
The classic ladder file is attached.
Put this in your main hal file
Code:
# Load classic ladder
loadrt classicladder_rt numPhysInputs=15 numPhysOutputs=15 numS32in=10 numS32out=10 numFloatIn=10 numFloatOut=10 numBits=50 numWords=50
addf classicladder.0.refresh servo-thread
# TODO switch back to this later loadusr classicladder --nogui custom.clp
loadusr classicladder custom.clp
Then in your post_gui (as you'll need some of the pins that load).
Note that pdnt pins are for my pendant the general lines are above but commented out:
Code:
########### SETUP THE MACHINE LIGHT #########
# Turn on the machine light to red to kick things off.
setp hm2_7i96s.0.7i76.0.1.output-12 true
net greenlight hm2_7i96s.0.7i76.0.1.output-10 classicladder.0.out-02
net yellowlight hm2_7i96s.0.7i76.0.1.output-11 classicladder.0.out-01
net redlight hm2_7i96s.0.7i76.0.1.output-12 classicladder.0.out-00
net e-stop halui.estop.is-activated classicladder.0.in-00
#net pwr-on halui.machine.is-on classicladder.0.in-01
net machine.is-on classicladder.0.in-01
#net prg-run halui.program.is-running classicladder.0.in-02
net pdnt.program-is-running halui.program.is-running classicladder.0.in-02
#net halui.program.is-idle classicladder.0.in-03
net pdnt.program-is-idle classicladder.0.in-03
The classic ladder file is attached.

I have a question which may be version related. This line:
net yellow-in1 <= halui.machine.is-on => and2.0.in0
gives me the error:
/usr/share/linuxcnc/hallib/qtplasmac_comp.hal:21: Pin 'halui.machine.is-on' was already linked to signal 'yellow-in1'
when I try to run this in version 2.9.3
Could anyone give me some insight into why, and maybe a way to make it work? I am a total newbie at HAL coding.

If you are not already using ClassicLadder, and don't want to bother adding it, it can all be done in hal as well.
I think I'd attack this something like this.
Code:loadrt and2 count=2 loadrt xor2 count=1 loadrt siggen num_chan=1 addf and2.0 servo-thread addf and2.1 servo-thread addf xor2.0 servo-thread addf siggen.0.update servo-thread setp siggen.0.frequency 2 #Yellow Light net yellow-in1 <= halui.machine.is-on => and2.0.in0 net yellow-in2 <= halui.program.is-idle => and2.0.in1 net yellow-out <= and2.0.out net yellow-out => hm2_7i76e.0.7i76.0.0.output-01 #(or what ever your output pin is for the yellow light) #Green Light net green-in1 <= halui.program.is-running => xor2.0.in0 net green-in2 <= halui.program.is-paused => and2.1.in1 net flash <= siggen.0.clock => and2.1.in0 net green-flash <= and2.1.out => xor2.0.in1 net green-on <= xor2.0.out => hm2_7i76e.0.7i76.0.0.output-02 #Red Light net red-on <= halui.estop.is-activated => hm2_7i76e.0.7i76.0.0.output-00 #(or what ever your output pin is for the red light) (I just have a big red light on each of our machines that turns on when they are not running a program.)

The error appears because you are reassigning 'halui.machine.is-on' to a signal (even though it is the same one).
change:

Hmmm... my question would be is, how would I input the machine power state into the and2.0.in0 and the machine idle state into the and2.in1?
Wouldn't I have to be able to get the signal from halui.machine.is-on and halui.program.is-idle into the and2 inputs to accomplish the desired output?
I would also be faced with a similar issue in the subsequent code block:
The intent in this block is that if the machine is running, the green light is solid; if the program is paused, then it is flashing.
Not sure I see the connections here with your suggestion -- could you maybe explain the logic a little?

As requested. I have 5 status LEDs on the face of the control box; I am trying to light them to reflect the status of the machine. The machine itself works perfectly -- it is the status light code that I am having trouble with.

The conflict is between your halfile and 'hallib/qtplasmac_comp.hal':
Your halfile seems to get called first and 'halui.machine.is-on' is connected to the signal 'yellow-in1'. Then 'qtplasmac_comp.hal' is loaded and it wants to assign the same pin to a different signal which causes the error.
Open '/usr/share/linuxcnc/hallib/qtplasmac_comp.hal' and see which signal name it wants to connect 'halui.machine.is-on' to and use that signal in your halfile:
Change:
To:
/usr/share/linuxcnc/hallib/qtplasmac_comp.hal:21: Pin 'halui.machine.is-on' was already linked to signal 'yellow-in1'
