 CBE20 Communication Board The CBE20 Communication Board can be used to connect to a PROFINET IO network via a CU320-2 Control Unit. The SINAMICS S120 drive system therefore 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 Ојs
- Connection to control systems as PROFINET IO devices in accordance with PROFIdrive, 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
- Supports the functions "media redundancy" and "shared device"
The CBE20 Communication Board is required if: - a SINAMICS S120 or SINAMICS S150 converter with a CU320‑2 DP Control Unit (PROFIBUS) should be connected to a PROFINET-IO network
- SINAMICS Link is to be used to directly exchange data between several CU320‑2 DP (PROFIBUS) or CU320‑2 PN (PROFINET) Control Units without using a higher-level control system
- EtherNet/IP connectivity is required.
