[etherlab-users] No CoE communication

[Graeme Foot]

Hi,

I've been asked to let you know what master version and patches I'm using.  I'm still running an old version (2526 from the stable-1.5 branch, 12/02/2013).  The script I use to download it is attached (004-etherlab_master).

I use buildroot to create my linux system, so the script  tar's the master folder and puts it in the buildroot downloads folder.  Note: I also use a really old buildroot from 2012 with a few modifications, but I have attached the mk file that it uses.

The patches that I apply are also attached.

The build options I use are:
--with-linux-dir="<linux dir>"
--enable-cycles
--enable-rtdm
--enable-e100
--enable-e1000
--enable-e1000e
--enable-cx2100


I use RTAI, but that shouldn't make any difference.


Regards,
Graeme.

Remember to reply-all to mail the forum as well.

Line 85 has: #define Yaskawa_Sigma7  0x00000539, 0x02200301 This is different to my drive, so it may still be the Sigma 7 id causing a mismatch, but it is the id being returned from the ethercat struct command.

Other than that, I've got no idea.

Graeme.

Hi Graeme,

I understand I have been mailing a lot, my questions may seem repetitive.

The positive now is I was able to get to OP state by forcefully setting 1c12 and 1c13 to 0 (PDO assignment fro SM2 and SM3).

I am still not able to configure the PDOs though. What I have narrowed down to is, somehow CoE communication just does not happen. I was going through the etherlab forum and came across a post where they mentioned some sdo's had to be set prior to configuring the PDOs. Is it that ?

Also, It would be great if I could just reach out to you on your phone if thats not an issue. Could sort out my problems faster and not disturb you with constant emails. Do let me know if thats an option.
Thank you so much.

Regards,
Rahul
