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

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.

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

Lcnc 2.7 Axis
PS
The scheme needs improvement

This works fine.

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

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.
