In order to assign real-time capability to a standard Ethernet port of an IPC controller, the Beckhoff real-time driver has to be installed on this port under Windows.
This can be done in several ways. One option is described here.
Open the Device Manager by right clicking “My computer” and selecting control panel. Look under Ports (COM & LPT). You should see an open port named 'USB Serial Port' Right click on the 'USB Serial Port' and choose the 'Update Driver Software' option. Next, choose the 'Browse my computer for Driver software' option. If the device-specific driver is distributed through Windows Update, you can manually update the driver by using Device Manager. For more information about how to do this, see update drivers in Windows 10. If the device is not yet connected, first install the device-specific driver, such as by using the appropriate installer. If you’re using any Xiaomi device or any Qualcomm powered device and want to flash MIUI ROM or unbrick your dead device, then Qualcomm HS-USB QDLoader 9008 driver will be useful. Any of the Android devices which are running on a Qualcomm processor will be applicable for it.
In the System Manager call up the TwinCAT overview of the local network interfaces via Options → Show Real Time Ethernet Compatible Devices.
This have to be called up by the Menü “TwinCAT” within the TwinCAT 3 environment:
The following dialog appears:

Interfaces listed under “Compatible devices” can be assigned a driver via the “Install” button. A driver should only be installed on compatible devices.
A Windows warning regarding the unsigned driver can be ignored.
Alternatively an EtherCAT-device can be inserted first of all as described in chapter Offline configuration creation, section “Creating the EtherCAT device” in order to view the compatible ethernet ports via its EtherCAT properties (tab “Adapter”, button “Compatible Devices…”):
TwinCAT 3: the properties of the EtherCAT device can be opened by double click on “Device .. (EtherCAT)” within the Solution Explorer under “I/O”:

After the installation the driver appears activated in the Windows overview for the network interface (Windows Start → System Properties → Network)
A correct setting of the driver could be:
In most cases an Ethernet port that is configured as an EtherCAT device will not transport general IP packets. For this reason and in cases where an EL6601 or similar devices are used it is useful to specify a fixed IP address for this port via the “Internet Protocol TCP/IP” driver setting and to disable DHCP. In this way the delay associated with the DHCP client for the Ethernet port assigning itself a default IP address in the absence of a DHCP server is avoided. A suitable address space is 192.168.x.x, for example. |
