AX58100 was created by SOLD

Hello
I'm a newbie. I started DIY Ethercat board with AX58100
1. AX58100-16in-16out
2. AX58100-Step/DIR + Encoder ABZ +8in/8out GPIO

Everything works on Twincat and I can connect it to Linux lcec

I want to use it with Linux CNC as 3axis and 1 spindle
In the axis there are
-Step/Direct
-Input8
-Output8
-Encoder ABZ
And there is AX58100-16in-16out board as the main I/O of the system

But I still can't create the correct ethercat-conf.xml file. I don't understand if it needs to be used as CIA402 or not
I have attached the XML files from AXIS for both boards

Can you please suggest a generator for ethercat-conf.xml for this project

Thanks for your support

I got a reply email from the AX58100 manufacturer saying that it is not possible to use only AX58100, need to use external MCU via SPI.

But no answer about working as IO. I want to know if not using CIA402 can still be declared as input/output.

I created ethercat-conf.xml used IO 8in-8out successfully.it works.

Pretty cool. I assume that there is no gateway IC that woul parse the ethercat messages but the chip itself is pretty cool.
I assume that you can still use the pwm, encoder etc features as a "standalone".
Where did you get the chip and how much did you pay for it?

Yes, it can't process by itself, as the manufacturer replied by email.
I tried step/direct with factory XML via twincat, it works. I'm still new to ethercat, I can't do much more.
This demo board is available on Alixprees th.aliexpress.com/item/1005005600858798....arch%7Cquery_from%3A

Here is an interesting discussion regarding IC AX58100 designed by Håkan BåstedtMetalMusings
github.com/MetalMusings/MyOwnEtherCATDev...uecomment-2474082363. With the kindly given instructions I have my board working and ready to run on LINUXCNC

Yes, it went well. Both your card, COFHAL, and SOLD's system were able to start and are now working.

Background: I have been making a few EtherCAT client cards, just to see how it can be done, to learn about EtherCAT and eventually use a card in my plasma cutter which is slowly being built. If all goes well.

I publish the project on github.com/MetalMusings/MyOwnEtherCATDevice and I made a series of Youtube video as I learned things along the way.

The card we were working on was the EaserCAT 3000

Looks great!
Shame it seems that it does not have an analog input, with one of those you could of done the arc voltage reading directly without the need for a mesa pcb in between.

Well actually you seem to have a microcontroller on there as well that most likely has an ADC, why not use one of those? I did not check the schematic but will take a peek at somepoint.

Entirely possible.
There is an STM32F407VGT6 but you can switch it for your favorite MCU if needed.
Now, I am not an electronics engineer even if I do this kind of things. With that said I imagine one would need some electric isolation before the arc voltage reaches the MCU pins. One "just" needs a circuit to read the arch voltage that the MCU can read.

These are just my opinions but, you dont need isolation and you would not design to read the raw arc voltage. Most decent plasma's will give you a divided arc voltage output, most common divider ration being 50. So an arc voltage of 100, would read as 100V/50=2V. You probably only need some filtering, input buffer and over voltage protection.

I took a quick look at the AX schematic, seems its only used as a gateway and none of the "special" features are used. This begs the question, why the AX instead of the LAN9252? To me the AX seems hard to get, are there benefits to use the AX as a gateway?

What are your plans for the plasma build? Do you need the MCU to do the step/dir? Or could you just get an ethercat drive and let that handle the motion side? Then you could probably use a much simpler (cheaper and smaller) MCU for IO, Analog input, maybe an encoder for pendant etc.
