PROFINET (Process Field Network) is an Industrial Ethernet protocol. It uses TCP/IP and is real-time capable.

X20 modules or other modules based on X2X Link can be connected to the bus controller. Modular system configurations are optimally supported by PROFINET. Using the device description file (GSDML format), it is very easy to handle project configuration in the respective engineering tool from the manufacturer of the master device.

System modules for bus controllers:
1. X20BB80 X20 bus base, for X20 base module (BC, HB, etc.) and X20 power supply module, X20 end cover plates (left and right) X20AC0SL1/X20AC0SR1 included
2. X20PS9400 X20 power supply module, for bus controller and internal I/O power supply X2X Link power supply
3. X20PS9402 X20 power supply module, for bus controller and internal I/O power supply, X2X Link supply, supply not galvanically isolated
