Adding new objects to AM335x EtherCAT Sample Code

taeyun kwak

Hi, I implementing CiA402 slave device using SSC5.01 and using latest build of TwinCAT as EtherCAT master.

I modified "cia402appl" and "tiescappl" in order to implement CoE,
But there's a problem that the number of object limitation....
(I added over 60 objects but twincat doesn't show all of that....)

I'm gonna test with ti sample ethercat source on the guess that my source is wrong.
I want to add some objects for test, but tiescappl.h object structure is different to cia402appl.h.

The question is How can I add SDO or PDO in ti sample ethercat source?
And there's "the number of object limitation"?

I've already patched SSC files using AM335x SDK GSG document.

Thanks,
Teyun.

Teyun-san,

great to hear you are using our solution. But TI is only responsible for the lower layers of EtherCAT here. As you know we are using the Beckhoff SSC as an example stack to be used with our implementation. If you need further support on this or additional features please contact Beckhoff or ETG. There is also an active forum on www.ethercat.org.

In addition you might want to check any of the active 3Ps in that area. Usually they do offer configuration tools with their stacks that automatically generate C code from a high-level device description. That is a more automated and safe way to implement EtherCAT slave devices.

Regards.

Hello,

the same issue was already discussed in the ETG forum.
