Thanks John, I've got classic ladder in the gui working now.

[chazmtu]

OK, I'm almosts finished but I'm getting an error that I can't figure out. My postgui.hal file looks like this:

#set up the z-axis touchoff button
net remote-z-axis-touchoff classicladder.0.in-00 <= pyvcp.z-axis-touchoff
#set to mdi mode
net halui.mode.is_mdi => classicladder.0.in-01
#wait for motion to finish
net motion.motion-inpos => classicladder.0.in-02
#mdi command 1
net z-touchoff classicladder.0.out-00 => halui.mdi-command-00
#mdi command 2
net z-zero classicladder.0.out-01 => halui.mdi-command-01
#mdi command 3
net rapid-away classicladder.0.out-02 => halui.mdi-command-02

my ladder program is set up just like chester88's example. I get an error like "signal name 'motion.motion-inpos' must not be same as a pin." when trying to start emc. Any suggestions? I'm moderately sure the rest of my postgui code is right.

[chester88]

ok try:
net in_pos motion.motion-inpos => classicladder.0.in-02
bet you got an error for:
net halui.mode.is_mdi => classicladder.0.in-01
try:
net mode halui.mode.is_mdi => classicladder.0.in-01

these two lines you did not specify signal names

[chazmtu]

Yep you were right but now I get a new error," 'halui.mode.is_mdi' does not exist". If I understand correctly it controls a bit that is true when I'm in the mdi window in axis? I was using the mdi command buttons in auto mode too, any reason why we can't do without it?

[chester88]

You added HALUI=halui to the ini file? I would bet this is the first line that tries to connect to halui pins? yes?
can you show the pins to if halui has been loaded? (add 'show pin' to your HAL file)
I see another way to load halui is to add:
loadusr halui -ini /path/to/inifile.ini
to your custom HAL file (change the path to whats apropriate)

[chazmtu]

Yeah I added HALUI=halui in my .ini file, and it looks like the first to try to connect to halui pins. I tried your alternate way to load halui with the same results. I don't understand the show pin thing though. I put that alone in my hal file? I still get the error when I do that. Does "halui.mode.is_mdi" refer to a line the halui section of my ini file because all I have is HALUI=halui and my three mdi commands.

[chester88]

sorry I should have been more specific:
add the show pin line before the line that errors.
run emc in a terminal window (open a terminal window and type emc)
then when it gets to that line it should print out all the pin names.
then check to see if the halui pins are present.
If not then that is the problem.
I am not home for a few more days so i don't have a linux box available to help you
much. maybe John will see this thread and join in again....

[chazmtu]

Neat trick. It lists the pin as halui.mode.is-mdi instead of is_mdi so I changed it and emc will boot now but the button still does nothing in manual or mdi mode. The console does show an error though:

ULAPI: WARNING: module 'HAL_classicladder' failed to delete shmem03

[chester88]

The error is prob not a problem, pretty sure it about when the GUI closes that it didn't
erase the shared memory and we don't want it to.
can you open the classicladder gui and see that your program is loaded and that the pyvcp button registers on and off in classicladder?

[chester88]

sorry about the pin name error - the wiki is wrong-I will fix it later the manual is right though.

[chazmtu]

Actually I just checked that using halmeter. The pyvcp button registers as well as the two classic ladder inputs. The mdi command pins don't when I press the button. I can't find a way to measure the %B0 and %B1. Do they always start false?

[chester88]

you need to open the classicladder gui and click vars button then you can see the %B0 and %B1 variables plus watch the ladder logic work

[chazmtu]

All I get is a blank window. My machine is having trouble updating buttons on so many windows. I think its locking up when I load my ladder program. I'm gonna give it another couple tries though.

[chazmtu]

OK here's what I get. %I1 and %I2 are on when I start and %I0 is on when my button is pressed but I cant see any change in %B0 or %B1. There's no change in any of the outputs either.

[chester88]

ok but you haven't told me if the ladder program is present-the last post said it was blank. I need clear info. If you dont see the program then it is not loaded and nothing will work If that is true you could try to load it from the classicladder window. I would bet the ladder program is not in the right directory or else the name is different from what you added to your HAL file. You remebered to add the .clp to the end of file name?

[chazmtu]

My ladder program is in the same directory as my .hal and .ini files and I double checked the spelling in my hal file. What I meant was when I load my ladder file into the Classicladder gui, the buttons and fields in the classicladder windows don't appear. I can still hit them and bring up whatever the button in that place would do but I cant see the checkmarks in the vars window. Is there another way to check if my classicladder program is running?

[chester88]

ok i understand u are getting to the limit of computer power....can you put Hal meter on classicladder.0.out-00 and see if it changes to true. It will not change for long and that may be the problem...Sorry when I get home i can try a few more things.

[chazmtu]

I didn't see it change. I tried it with hal scope also with classicladder.0.in-00 and classicladder.0.out-00 as my signals so I could see better but no change in output when the button was pressed.

chazmtu, can you zip or tar up all of your config files and post it online somewhere like http://filebin.ca/ this way I can see exactly what you see... sometimes six eyes are better than two
