The CBE20 Communication Board can be used to connect to a PROFINET IO network via a CU320?2 Control Unit.

The SINAMICS S120 then assumes the function of a PROFINET IO device and can perform the following functions:

• PROFINET IO device
• 100 Mbit/s full duplex
• Supports real-time classes of PROFINET IO:
  
  • RT (Real-Time)
  • IRT (Isochronous Real-Time), minimum send cycle 500 ?s
• Connects to controls as PROFINET IO devices using PROFIdrive compliant with Specification V4
• Standard TCP/IP communication for engineering processes using the STARTER commissioning tool
• Integrated 4?port switch with four RJ45 sockets based on the PROFINET ASIC ERTEC400. The optimum topology (line, star, tree) can therefore be configured without additional external switches.

With SINAMICS firmware V4.5 and higher the CBE20 Communication Board also supports an ODVA EtherNet/IP protocol stack.
