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

With the CBE20 Communication Board, SINAMICS S120 and/or SINAMICS S150 is a PROFINET IO device in the sense of PROFINET 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.

SINAMICS Link

SINAMICS Link can 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. In this case, the CBE20 Communication Board is required. Possible applications for the SINAMICS Link include:

• Torque distribution for several drives
• Setpoint cascading for several drives
• Load distribution for drives coupled through a material web
• Couplings between SINAMICS G or SINAMICS S with the CU320‑2 Control Unit and SINAMICS DC Master with CUD Control Units.

Participants other than the CU320‑2 Control Units and/or the CUD Control Units of the SINAMICS DC Master cannot be integrated into this communication.

SINAMICS Link is activated by appropriately parameterizing the Control Units of the participants.
