ABB DSBC172 57310001-KD Bus Supervision Board

Core Protocols:

Master/Slave Functions: Can serve as an EtherCAT master or CANopen master/slave, flexibly accessing networks with different topological structures.

High-Precision Clock Synchronization: Integrates a hardware clock synchronization mechanism (such as EtherCAT-specific synchronization protocols) to ensure action consistency of multi-node devices (synchronization error ≤1μs).

Data Preprocessing: Built-in data caching and real-time scheduling algorithms reduce communication delay (typical delay ≤200μs), supporting fast transmission of periodic real-time data (e.g., motor position, speed commands).

Software Compatibility: Compatible with ABB control system software (such as RobotStudio and AC 800M programming environments), supporting configuration of bus parameters, node mapping, and synchronization strategies through a graphical interface.

Hot-Swap Design: Enables module replacement during system operation, reducing downtime (requires coordination with control cabinet power management).

Wide Temperature Range: -20°C to +60°C, adapting to harsh industrial environments with high temperatures and dust.

Anti-Interference Certification: Complies with CE and UL standards. The electromagnetic compatibility (EMC) design resists electromagnetic interference from devices like frequency converters and motors.

Hardware Environment: Suitable for ABB controller racks (such as AC 800M) or standard DIN rails. Reserve heat dissipation space (module spacing ≥15mm) and keep away from strong electromagnetic sources (e.g., frequency converters, transformers).

Tools and Accessories: Screwdrivers, anti-static wristbands, EtherCAT special cables (shielded twisted-pair cables), CANopen terminal resistors (120Ω for bus ends).

Safety Notes: Operate with power off, wear anti-static equipment, and avoid touching the circuit board; confirm that the bus type matches the module interface (EtherCAT requires distinguishing the master-slave interface direction).

Rack Installation: Insert into the specified slot of the ABB controller rack (such as Slot 3-5), lock with fixing clips to ensure firm contact between the gold fingers and the backplane.

Independent Rail Installation: Fix the DIN rail in the control cabinet, snap the module onto the rail, and lock it with clips. Vertical installation is recommended to optimize heat dissipation.

Power Supply Wiring: Connect to the 24V DC power supply (marked "+24V" and "GND"), use 1.5mm2 cables, and ensure correct polarity.

Bus Wiring:

Grounding Treatment: Connect the module grounding terminal to the system grounding bus. The bus cable shielding layer should be connected to the control cabinet grounding post to avoid multiple grounding points.

Hardware Confirmation: Check that the module is installed without looseness, the wiring has no short circuits (measure the resistance between power terminals with a multimeter ≥100kΩ), and the EtherCAT cable is properly plugged in (RJ45 indicator light is flashing).

Software Configuration: Add the module model (DSBC172) in ABB programming software, assign bus addresses (such as CANopen slave addresses 1-127), and set EtherCAT master parameters (such as cycle time and synchronization mode).

Indicator Light Status:

EtherCAT Jitter Test: Use an oscilloscope to measure the periodic fluctuation of the synchronization signal, requiring an error ≤1μs (typical value 0.5μs).

Data Cycle Test: Send periodic commands (such as a 1ms cycle) through the PLC and measure the slave response delay, requiring the overall delay ≤500μs.

Fault Injection Test: Simulate bus disconnection and node failures to confirm that the module has error detection and recovery mechanisms (such as automatically skipping faulty nodes and triggering alarm signals).
