Hello, Respected NI engineers!
I had a different interpretation of following articles.
How to use the NI 9144 EtherCAT slave chassis with 3rd party EtherCAT master tools?
and
Making NI 9144 chassis expansion PC based
As I have understood, in the first one is said that 9144 chassis can be used without the controler (cRio/PXI).
But at a forum (2 reference) it is specified that the controler is necessary.
Therefore a question: whether probably to use 9144 chassis (with support EtherCAT) without the controler?

Hi kolan,
The 9144 requires an EtherCAT Master. As the first article explains, this doesn't need to be a CompactRIO or PXI chassis, just a system that can act as a EtherCAT Master. The forum also mentions the need for an EtherCAT Master.

So, does that mean that we can use PC-based Ethercad Master cards such as are presented under the reference?

Thanks for Your reply, Jareds!

Hi Kolan,
Exactly. A PC-based EtherCAT Master card should work just fine as long as it follows the EtherCAT standard.
