Setting up: PROFINET Controller/Device

The usage of the PROFINET real-time protocol is possible for the device (slave) or controller (master) supplement with the CU2508. 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.

Setting up: PROFINET Controller/Device 1:

Availability

This function can be used from TwinCAT 2.11R3 build 2234.

Setting of the PROFINET Device or Controller adapter

Once the CU2508 has been activated as Multiple Protocol Handler in the system and the relevant ports have been enabled, you can select an "Adapter Referent" under the "Adapter" tab for the Controller or the Device. Enter the port through which you want to operate PROFINET.

Setting up: PROFINET Controller/Device 3:

No other special considerations are required for the CU2508; you can proceed as usual.
