What IO module?
If its not beckhof, you need to make a custom xml file.
With just the io module connected type
ethercat slaves -v
ethercat pdos
You will have all the info to build a xml file similar to slave1 here
github.com/rodw-au/linuxcnc-cia402/blob/...ercat-conf-diewu.xml

So I am trying to get a Weidmuller UR20-FBC-EC IO module integrated.
I tried my best to make the xml file.
I had a few doubts though...
On line 6 what are these responsible for:
appTimePeriod="1000000"
refClockSyncCycles="1"
On line 7 what are these responsible for:
type="generic"
configPdos="false"
On line 8 what are these responsible for:
assignActivate="300"
sync0Cycle="*1"
sync0Shift="0"
I have also attached the xml file with this post.
At the end of the file there are 3 commented out sections that have the response to:
ethercat slaves -v
ethercat pdos
ethercat sdos
Not sure if that is any help or not but just thought maybe the extra information may be useful. Please ignore it if it's useless.
Now I do have another question. After this custom xml file is generated, how do I go about integrating it with linuxcnc?
Thanks again for you help

LINE 6 = servo thread length. must agree
LINE 7 generic. because it does not have built in support so you are creating a generic slave
LINE 8 I just accepted.
halpin = the name you wil call this as a pin in linuxcnc so it cannot have spaces
vid and pid are as in your slaves -v
vid = Vendor Id: 0x00000230
pid = Product code: 0x4f911c30
Probably other errors that i am not familiar with but a good start.

Thanks you for that prompt response, I appreciate your effort.
I've attached the xml rectifying the hal pin spaces and updated the PID and VID.
Can you point me to any resource on how to integrate this xml file into Linuxcnc so that it reflects in the HAL configuration window?
Right now its just kinda sitting in my config folder...

I can't help any further except to say configpdos should be true (I think)
If you ignore the cia402 stuff, this example shows how to load from your halfile
github.com/rodw-au/linuxcnc-cia402/blob/main/cia402.hal
The sticky at the end shows how to use halcmd to do basic testing.
Expect errors so do at the command line so yo see them..

Hi Rodw,
Thank you for your input, it helped me a lot in figuring out the problems, I followed the link you shared and then circled back to an old post of yours and realised linuxcnc-uspace-dev hadn't been installed as well. Super embarassing but I finally managed to get lcec to show in the hal configuration.
So, once again thanks for the help.

Hi,
I'm trying to get a module working that is not already supported and I hope someone can help me. I followed the instructions on the first page of this thread as best I could.
First I was trying to get an EL3068 8 port analog card working and it was successful. I'm using it to read some potentiometers.
Now I'm trying to get an EL5102 module working and I thought this would be the easier one since the EL5101 is already supported. After following the process linuxcnc doesn't complain about it being in my hal file but the module doesn't leave preop stage.
I copied the EL5101.h and EL5101.c files to lcec_El5102.h and .c
modified them to substitute 5101 to 5102 and changed the ProductCode field (from ethercat xml -p7)
I didn't try adding the second channel in the .c file. I looked but how to do it wasn't obvious.
did make clean and then make
cp lcec.so ../../linuxcnc-dev/rtlib/
sudo cp lcec_conf /usr/bin/
cp lcec_conf ../../linuxcnc/configs/wedm/

I'm sure I did a bunch of other stuff after following his instructions but I didn't document exactly what I was doing and don't quite remember. However, apart from this card it is mostly working. I/O is working and my ethercat drives are moving are moving the servo motors. I have a separate issue related to a belt reduction but that should probably be in another thread.

I think you are out of date here
The Pi4 is supported on the LInuxcnc Downloads page.
The image includes the current repository for ethercat
Follow these steps forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step
There has been a lot of work in recent months. You hardware could be supported now. If not ask, it might get supported.

yes I'm not at the most recent version, thank you for your quick reply.
I have upgraded to the more recent ethercat library as mentioned in New LinuxCNC-Ethercat git tree .
My devices folder is under linuxcnc-ethercat/src/devices and I didn't have to do the part where I added the device to lcec.config.c & lcec.config.h files
I guess I will try rebuilding from scratch but overall it is working with just this one module EL5102 not supported. The other unsupported module EL3068 I was able to get working and my other common i/o modules work so the ethercat part is working.

If possible, it would be good if you could do a pull request to Scotts repo to add your drivers. MAybe ask on the other thread
