Subsequently the required Ethernet couplers/boxes/drives can be manually added or scanned. Before a
scan TwinCAT should be restarted once in the Config/FreeRun mode.

Notes on the device
• An EAP (poll) adapter must be created in the configuration in order to operate a CU2508 downlink port
as an EAP real-time Ethernet interface for IO devices (BK90xx, EK90x).
• The EAP (EtherCAT Automation Protocol) is operated here in the so-called polling mode
• At least TwinCAT 2.11R3 is required for operation on the master side.
Setting up the real-time Ethernet device
For the setup a real-time Ethernet adapter is to be created as usual.

Fig. 60: Selection of the device for BK90xx and others
Not an actual port of the PC, but rather a virtual adapter of the CU2508 is then merely selected as the
Ethernet adapter for the CU2508.
