Overview
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 func-
tion 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
μ
s
•
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.
■
Integration
The CBE20 Communication Board plugs into the option slot on
the CU320-2 Control Unit.
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 CU320-2 Control Units and/or
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.
