TMS320F28388D: Connect DSP to DSP via EtherCAT

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Hello,

I am working with a solid-state transformer where I connect six ac-ac converter modules in series each with its own DSP controller. There are six modules in total and six DSP in total. The DSP's then communicates with another DSP using EtherCAT. I just wanted to know what software I need apart from Code Composer and TwinCAT 3 to communicate between the controllers. Can I use the 388D as a master and communicate with the 388D as a slave?

Regards,
Yousef

What we have is available in C2000WARE. Please see the User's Guide in the install directory below:

No, it can only be used as an EtherCAT slave device. TwinCAT can be the master for your initial testing.

Best,

Kevin

Thank you,

Kevin.

I have one more question. If I want to use it as master controller, Matlab also has such packages, why use twinCAT when Matlab is more universal?

Hi Yousef,

I'm not familiar with what MATHWORKS provides for EtherCAT support. Do you have some links or references to share?

TwinCAT is provided by Beckhoff, who defines the EtherCAT standard. It is a pretty universally used ECAT Master as well.

Best,

Kevin
