  • I can not see my EtherCAT device in NI Measurement & Automation Explorer (NI MAX).
  • How can I check my EtherCAT device is connected to my computer?
  • I have an EtherCAT device connected through a Real-Time Controller.¬† I can see the Controller and the other devices I have connected to it from NI MAX, but cannot see my EtherCAT.


Make sure you have installed the latest version of drivers NI-Industrial Communications for EtherCAT and also Industrial Controller Device Drivers . For checking your installed drivers and their version see Determine the Version of the NI Software Installed on My Computer.

Once you have the newest version of these drivers follow the Setting Up EtherCAT on NI Programmable Automation Controllers tutorial.

Additional Information

If you use NI MAX to install NI-Industrial Communications for EtherCAT software on a Real-Time Controller, some controllers, such as the Embedded Vision System, require you to install the Industrial Controller Device Drivers of the same version. If this driver is not installed, NI MAX will be unable to discover the controllers.
