Integration via a CU2508 real-time Ethernet port multiplier (Real-Time Ethernet interface)
Below, we show you how to configure a PROFINET Device using the CU2508 real-time Ethernet port multiplier.
However, you can use only one controller or device, if they are in a unique network. If the networks a physically separated, it is possible to use more than one controller or device supplement with one CU2508. This is due to the fact, that the CU2508 uses only one MAC address. The function of several PROFINET segments can only be secured, if the MAC address in a network segment is unique and there is no connection to other networks.
- 1. Add the CU2508 real-time Ethernet port multiplier to your TwinCAT project by right-clicking on I/O - Devices > Add New Item and adding the Real-Time Ethernet Adapter (Multiple Protocol Handler) in the window that opens.
- 2. Furthermore, the following settings on the Ports tab are necessary for the operation of the CU2508
Virtual Port Selection via:
EtherCAT Switch Link Protocol (ESL) (CU25xx required)
- 3. The PROFINET protocol is directly added to the I/O device. Four different PROFINET I/O devices are available for selection. Select PROFINET I/O Device (RT) according to the configuration with the CU2508.
- The available adapters are displayed directly when appended and are now available for selection. If these are to be modified or checked afterwards, this can take place on the Adapter tab.
- 4. Right-click the created PROFINET Device and select Add New Item to integrate a box in the form of a GSDML.
- 5. The following window then opens. At this point, select the PNTC Device (TwinCAT Supplement) and confirm with OK.
- 6. In the dialog that opens, Insert Device, you define the version with which the PROFINET Device should be integrated. Confirm your choice with OK.
