The CBE20 Communication Board is required, if

• a SINAMICS S120 or SINAMIC S150 converter, equipped with a CU320-2 DP (PROFIBUS) Control Unit, is to 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.

With the CBE20 Communication Board, SINAMICS S120 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 ?s
• Connects to controls as PROFINET IO devices according to the PROFIdrive profile
• 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.

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 or the CUD Control Units of the SINAMICS DC Master cannot be integrated into this communication network.

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