Ethercat Cable Redundancy

Hello everyone

Now I am facing a demand. I don't know if you know Ethercat cable redundancy.
At present, I have successfully used linuxcnc+Ethercat to control a three-axis laser machine tool. However, according to customer needs, I not only need to achieve ethercat communication, but also need to achieve cable redundancy to ensure that the equipment is still online when one end is disconnected.

Have you done anything like this before? Or give me some ideas, thanks

it works at some of my installations...

etherlab.org/download/ethercat/ethercat-1.5.2.pdf

first you have to recompile the master with the --with-devices option.
If you have installed with ec-debianize, edit the rules file in the debian folder.
then build-package again and reinstall.
After this you have to specify the backup devices mac adress in the ethercat config file MasterX_Backup (X is the number of the master to backup) .

sudo-update-ethercat and reboot....

Thank you very much for your reply
I will study your document carefully

I have great admiration for your technical achievements

Thank you very much for your explanation. I read the document you provided, but I don't understand how to modify the "the rules file in the debian folder" you said. What parameters should I change? (I'm already here)
 
I tried adding "--with-devices=2" after CONFIGS, but it didn't make ethercat redundant.

I already know the configuration method of the two parameters "--with-devices" and "MasterX_Backup" by reading the document.

I have configured MasterX_Backup as a backup MAC address, do I need other operations? 

I don't know by which method you installed the etherlabmaster.

If you have installed it with ec-debianize. you can edit the rules file
(/ec-debianize/etherlabmaster/debian/rules) on top of the file are the config flags for the Master defined. At this place you can add "--with-devices" and install the master again.

If you already have installed the master with "--with-devices" , everythins is fine.

Then you only have to edit the config file (etc/default/ethercat)

did you rebuild and reinstall the package ?

have you done sudo-update-ethercat ?

Yes, I did everything you said. But I'm not sure if my configuration in the rules file is correct?
 

please show the output of "ethercat master" at the status with both networkcards have connection.

Hi everyone
As I understand it, this feature works on level Etherlab master.
What about HAL/Linuxcnc?
