Configuration of a port as a PROFINET device

Requirement: TwinCAT 3 or TwinCAT from version 2.11R3 build 2234.

	Only one port per network segment You can configure and use any number of ports on the CU2508-0022 as PROFINET devices. However, two ports of the same CU2508-0022 cannot be used in the same PROFINET network segment. This is because all ports of the CU2508-0022 have the same MAC address. PROFINET does not allow two identical MAC addresses in one network segment.

A port can be configured either as a PROFINET controller or as a PROFINET device:

1. Right-click on “Devices” under “I/O” in the Solution Explorer and select “Add New Item…”.

2. In the window that appears, select either the type “Profinet I/O Controller (RT)” or “Profinet I/O Device (RT)” and confirm with OK.

Configuration of a port as a PROFINET device 3:

3. A list of the available ports of the IPC and the CU2508-0022 appears.
Configuration of a port as a PROFINET device 4:

If no list appears, set the port subsequently in the “Adapter” tab of the device you have just created, see chapter Changing the port of a device. Skip the following step.

4. Select the desired port of the CU2508-0022 in the list.
X01 is port 1, X02 is port 2, etc.
Please note that the selected port must not be configured as a TCP/IP port.
You can also select “(none)” and/or change the port afterwards. See chapter Changing the port of a device.

5. Configure PROFINET communication via the device you have just created.
