CL logic to make LCNC buttons work like industrial machines

I think he was. Having tried it myself in the past,. not sure I'd recommend it.

Did you find this? Might help.

Sorry for late answer
This file is ASCII. Easy to edit.
With a bit fiddeling you can understand f.x. that one rung is one line.
So moving a line to another position moves it.
I remember that i also replaced var names.... etc.

Honestly, i find CL a pain in the...
But to write real simple plc logic much more efficient than hal.
I'm a fan of iec61131.

Me too, I've never bothered to look at CL. becasue I've never programmed a PLC.
I'd just write a custom component in C which I think is Linuxcnc's jewel in the crown.

Its funny, there has barely been a mention of CL for ages and all of a sudden a few people are discussing it.

Make's sence to me.
If you are coming from standart automation world, plc programing is the absolute best way to go. C can only be acceptet for specialities. I f.x. dislike C as IT does not prevent me from my typos in concern of theses dam... ; 's. ;-()

I10 - ?
I11 - ?
I13 - ?

When you first start the program, almost always an error:
can't do that (EMC_TRAJ_SET_TELEOP_ENABLE) in auto mode with the interpreter paused

The scheme needs improvement

net mode:is:auto classicladder.0.in-14 halui.mode.is-auto

This works fine.

net auto classicladder.0.in-00 pyvcp.run
net feed-hold classicladder.0.in-01 pyvcp.feedhold
net program-idle classicladder.0.in-02 halui.program.is-idle
net single-block classicladder.0.in-03 pyvcp.step
net mode:is:auto classicladder.0.in-04 halui.mode.is-auto
net btn-stop classicladder.0.in-05 pyvcp.stop

net auto-mode-select classicladder.0.out-00 halui.mode.auto
net cycle-start classicladder.0.out-01 halui.program.run
net feed-resume classicladder.0.out-03 halui.program.resume
net single-block-select classicladder.0.out-04 halui.program.step
net program-stop classicladder.0.out-05 halui.program.stop

net feed-hold-select classicladder.0.out-02 halui.program.pause

I use at least a few rungs on every machine I do. There is always something easier to do in CL than HAL.

I once did a point to point Biesse with the zones, photocells pushbuttons and green lites's using CL.

I don't get any error messages when I use it (2.8.1). I have made a few changes to it since I posted this, nothing crazy, just centralized the grouping of the physical and gamepad buttons I was using. Pressing cycle start should bring the machine to auto mode, not alarm. I did, however, add halui.mode.is-auto to I6 after posting my file here.

To answer your other question, I10, I11 and I12 (formerly i13) are for a different circuit. Those are assignments to two separate probe circuits, using separate inputs and an internal relay to switch between them.

Long story short, my machines have a hardwired tool setter mounted to the table and a spindle probe. Both setter and probe are NC, so when the spindle probe is disconnected from the machine, the signal is broken, so the probe is in a constant trigger state. I12 is a relay that flags mcodes using sets probe-relay true/false. I12 is tied to both a classicladder input signal as well as spindle inhibit, so when the spindle probe is active, the spindle cannot rotate.

see attached. I commented at the top of each rung section. I make little tutorial videos on basic CL and HAL for youtube, so sometimes my samples get attached to my CL files, but they don't usually get in the way.
