Ethercat - Failed to register PDO entry: No such file or directory

Hello everyone,
I am currently trying to configure an EasyIO board from www.bausano.net/en/hardware/easyio.html which is an ethercat board with analog and digital IO.
I followed the Rodw post: forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step to install needed tools and the tutorial HERE to build my XML file (in attachment).
By the way, thank you very much to them and all the ethercat contributors for all their work.

Now the problem: when I try to load my config, I get this debug info:

Debug file information:
Note: Using POSIX realtime
Failed to register PDO entry: No such file or directory
LCEC: master 0 PDO entry registration failed
lcec: rtapi_app_main: Invalid argument (-22)
./hallib/ethercat.hal:2: waitpid failed /usr/bin/rtapi_app lcec
./hallib/ethercat.hal:2: /usr/bin/rtapi_app exited without becoming ready
./hallib/ethercat.hal:2: insmod for lcec failed, returned -1
144345
Stopping realtime threads
Unloading hal components
Note: Using POSIX realtime

I do not understand the "failed to register PDO entry", is it a rights problem? Maybe I forgot to install something?

gives me:

Do you have an idea about that? Pretty sure it is a silly mistake...
Thank you all

HI
<syncManager idx="0" dir="out/in">
out or in must have sequential numbering
Regards 

 

Hi jjdege,
Thank you for your answer, indeed the problem was the numbering.
I wanted so much to organize the IO that I did not noticed it, I feel silly now
Are you satisfied with the EasyIO board?

Hi Nalesque
I purchased and configured the EasyIO, not used yet, I use the FR4000 step/dir in EtherCAT, I'm switching to Delta servos and the EasyIO will be necessary for the cnc.
I'll tell you if it works
I think the analog in/out pins work with float and s32, I have to do some tests 

Well, I am currently trying to make the thing work...
In HALShow, EasyIO is online, oper and state is op, but IO does not react when I change state...
I'll let you know if I find out.
For the analog, I switched to float and did not revert

Hi Nalesque
I attach the xml file, tested and ok
I have tested the analog pins and they work two ways, s32 and float
with a value of 33000 from 9.95V

 

Hi !
Thank you for your tests and infos.
I realized that I'm stupid tired when I finally figured out that if the EasyIO communication was working but not the IO it is because I forgot to power the 24V Field of the board ! Now everything works perfectly
Thank you jjdege

Hi, I bought an EasyCAT fo ardino any trying to communicate with LCNC. 

I made the ethercat-conf.xml file what is attached below. On HALshow I see the pins, but I'm not able to communicate with the board with the test rig, what I also bought for the test. 

May I ask for some help with it?

HI
I get an error in the .xml file 

 

with the modified file, LCNC sees the pins,
test if the devices are op

Thanks, I'll correct it, but I'm pretty sure it is not the problem, since I commented complety out this part for testing.
Any other suggestion?
What arduino code shloud I use? Now I testing whith this code from examples: TestEasyCAT.ino
