Hello 
I have managed to get a few motors running with etherCAT, but I still need a simple I/O system with analog out and encoder input, to use a mesa THCAD.

How is it feasible? Do I need a dual Ethernet card? 
The PCs I’m using have a single Ethernet port, so to run both mesa and ethercat I will need another Ethernet system, to have different NICs, right?

thank you.

Hi,

I think this is what you are looking for:
www.linuxcnc.org/docs/html/gcode/m-code.html#mcode:m66

Hi,

The corbett install uses systemctl to start & stop the ethercat bus.
In debian 12 & 13 i use /etc/init.d/ethercat start.

At what time is your ethercat bus started, at pc boot time?

@Pcw,

Yes, that should work.
Script below works.

$ halcmd -s show pin halui.estop.is-activated
prints:
halui bit   OUT FALSE halui.estop.is-activated

Then get the FALSE or TRUE in a script:

Another possibility would be a script with halcmd  in a loop,
watching the desired pin/signal  (halcmd -s show pin spindle.0.on | grep TRUE)
(this could also turn off the spindle if LinuxCNC was not running)

Hi,

Here is a example project how to read & write to ethercat-master from any device.
I called the project twincat, because it is able to get and send info to the bus system.

The  ethercat-master source is slightly updated, It can print out more info as normal.
And the source had a nasty bug related to c code configuration wich i found.

This bug is still not resolved in etherlab master. I did tell them the bug, but i did not do a push request.

I think with this project you will be able to figur out how to use the TURCK device.
The project can print all details of the TURCK device. And you can send any data you want to the TURCK device.
1 bit send . Or 8bit, 16bit, and you can add more types if you need.

I run Home Assistant (open source, no cloud involved) which does a good job of managing the devices. It's not the interface to zigbee that's the issue -- it's the interface to HAL.

Is the NML channel documented somewhere?   [ Edit:  Never mind, I found it.   No, I won't be going there...  ]

Okay I got it... But how to customize them to not hard code them
 

In this case the answer is simple, just move the two variables above the ;; separator and create them as parameters. Then you will end up with independent static variables for each instance of the component. 

So:

You _may_ still be able to use the enum, that would be something I would experiment with to find out. If not you could create the state names as macros to preserve readability. (but you can always use something like:
)

Hi,

Maybe we can use the zigbee-api

Then we make a tiny connection to the nml channel, as a client.
Then the zigbee can follow the emergency status. on - off.
 

Right. that's exactly what I'm trying to accomplish -- disable the spindle with EStop. The spindle is a Makita router, with an on-off switch. I'd like to simply plug it into one of my zigbee-controlled smart switches, which are trivial to control from just about anywhere. Obviously a hard-wired relay would be better, but it's only a hobby mill, and that's not going to happen anytime soon.
