ABB DSBC176 3BSE019216R1 Bus Extender Board

EtherCAT: With a maximum transmission rate of 100Mbps, it supports periodic data updates (cycle time as low as <1ms), suitable for real-time synchronization in multi-axis motion control.

CANopen: Compatible with CiA 301/402 protocols, reaching up to 1Mbps, enabling networked access for sensors, actuators, and other devices.

Master/Slave Mode: Functions as an EtherCAT master or CANopen master/slave, flexibly adapting to topologies like chain and star.

Hardware Clock Synchronization: Integrates dedicated synchronization circuitry (e.g., EtherCAT synchronization protocol), ensuring multi-node synchronization error ≤1μs for consistent device operation.

Low-Latency Data Processing: Built-in caching and real-time scheduling algorithms enable typical communication delay ≤200μs, supporting fast transmission of real-time data such as motor position and speed commands.

Software Compatibility: Compatible with ABB RobotStudio and AC 800M programming environments, supporting graphical configuration of bus parameters and node mapping.

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

Industrial-Grade Protection: Wide temperature range (-20°C to +60°C), compliant with CE and UL certifications. The EMC design resists interference from frequency converters and motors in industrial environments.

Compatible with ABB controller racks (e.g., AC 800M) or standard DIN rails. Reserve ≥15mm spacing for heat dissipation, away from strong electromagnetic sources like frequency converters and transformers.

Tools: Screwdriver, anti-static wristband, EtherCAT-specific shielded cables, CANopen terminal resistors (120Ω).

Rack Installation: Insert into the designated slot of the controller rack (e.g., Slot 3-6), lock with fixing clips to ensure good contact between gold fingers and the backplane.

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

Power Supply Wiring: Connect 24V DC power (+24V/GND) with 1.5mm2 cables, ensuring correct polarity.

Bus Wiring:

Grounding: Connect the module's grounding terminal to the system grounding bus. The bus shield should connect to the control cabinet's grounding post to avoid multiple grounding points.

Hardware Check: Ensure the module is firmly installed, wiring has no short circuits (power terminal resistance ≥100kΩ), and EtherCAT cables are properly plugged in (RJ45 indicator flashing).

Software Configuration: Add the module model (DSBC176) in ABB programming software, assign bus addresses (e.g., CANopen slave addresses 1-127), and set EtherCAT master cycle and synchronization mode.

POWER: Steady on → normal power supply; off → check power wiring.

ETHERCAT/CAN: Flashing → normal communication; steady on/off → topology error (EtherCAT) or baud rate mismatch (CANopen).

SYNC: Steady on → synchronization successful; flashing/off → check synchronization parameters or master fault.

EtherCAT Communication Interruption: Likely due to poor cable contact or topology error. Replace cables and confirm master-slave interface sequence.

CANopen Node Unresponsive: Check baud rate configuration (e.g., 1Mbps), install terminal resistors, and scan nodes using CANopen diagnostic tools (e.g., PCAN View).

Module Overheating: Ensure ≥15mm heat dissipation spacing, ambient temperature ≤60°C. Add control cabinet fans if necessary.

Compatibility: The module must match the ABB controller firmware version (e.g., AC 800M firmware ≥3.2.1) to avoid communication issues.

Cable Selection: Use CAT5e or higher shielded twisted-pair cables for EtherCAT. For CANopen buses over 100m, reduce baud rate to ≤500kbps.

Maintenance Tips: Regularly clean dust from module cooling holes. Avoid use in high humidity environments (humidity ≤90%, no condensation).
