[Bahram]

Hello Dear Sir/Mam,
I am Dr. Bahram Tarvirdizadeh, a Staff Researcher in rehabilitation robotics at University College Dublin (UCD).
We have currently ordered the following product of NI:
https://www.ni.com/en-ie/shop/compactrio.html
https://www.ni.com/en-ie/shop/compactrio/compactrio-developers-guide.html

We want to send a command from the above system to the motor controller. We can select one of the following motor controllers:

#1: N5-2-1 EtherCAT https://en.nanotec.com/products/1603-n5-2-1-motor-controller-for-ethercat/

#2: N5-2-2 CANopen https://en.nanotec.com/products/1602-n5-2-2-motor-controller-for-canopen/

#3: N5-2-4 Modbus TCP https://en.nanotec.com/products/2143-n5-2-4-motor-controller-for-modbus-tcp/

#4: N5-2-5 Modbus RTU https://en.nanotec.com/products/2637-n5-2-5-motor-controller-for-modbus-rtu/

I want to ask you a question as follow:
Please kindly let me know, which of the above mentioned motor controller is compatible with the mentioned NI product.
Many thanks again.

Hi Bharam,

From my experience with CompactRIO, I would recommend choices #3 or #4.  EtherCAT or Canopen is a little more complex to use on CompactRIO.  I've used Modbus TCP from cRIO to control 3rd-party components before, without too many problems.
