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.

Setting up: Real-time Ethernet (BK90xx, ADS/RAW, EAP polling) 1: — Creating a new device

Setting up: Real-time Ethernet (BK90xx, ADS/RAW, EAP polling) 2: — 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.

Setting up: Real-time Ethernet (BK90xx, ADS/RAW, EAP polling) 3: — Selection of the CU2508 port to be used

The number of available ports (in this case 7) depends on the settings of the CU2508 device (see there).

Setting up: Real-time Ethernet (BK90xx, ADS/RAW, EAP polling) 4: — Adding the Ethernet devices

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.
