EtherCAT requires a special Ethernet adapter on the real-time controller to access the EtherCAT network. Complete the following steps to configure an Ethernet adapter for EtherCAT.
|Note By default, some real-time controllers, such as Real-Time Desktop controllers, do not have the special Ethernet adapter to connect to the network. Refer to the list of supported hardware in the NI-Industrial Communications for EtherCAT Readme for more information about the additional adapters that you can add.|
|Note MAX discovers all devices in the network, which takes a few seconds. If you cannot find the real-time controller after MAX displays all devices, select Remote Systems and press <F5> to refresh the list. If this operation does not work, ensure that you connect the real-time controller to the network with required software installed or contact National Instruments.|
|Note If the real-time controller has a customized Ethernet adapter, you must enable the customized adapter before selecting the adapter for the EtherCAT mode. Refer to the documentation of the real-time controller for more information about how to enable the customized adapter.|
|Note Do not select the primary adapter for the EtherCAT mode to control the EtherCAT slave, because this adapter is reserved for configuration and programming.|
|Note If you change the device mode to EtherCAT, you cannot use the device in an ordinary Ethernet network. Change the device mode back to TCP/IP if you want to use the device in the ordinary Ethernet network later.|
