The CBE20 Communication Board is required when:

• A SINAMICS G130 or SINAMICS G150 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
• EtherNet/IP is to be supported

With the CBE20 Communication Board, SINAMICS G130 or SINAMICS G150 is a PROFINET IO device in the sense of PROFINET and offers 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
• Connects to controllers as a PROFINET IO device 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 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. 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 CU320‑2 and SINAMICS DC Master with CUD

Nodes other than the SINAMICS CU320‑2 Control Units and 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 nodes.
