Description

DSBC172: Product Overview
The DSBC172 is a bus computer module designed for ABB’s S4C+ robot controller system. This critical component functions as the communication hub that manages data exchange between the main computer module and all other modules in the controller chassis. Installed in the main computer rack, it controls the backplane communication bus, arbitrating data transfers between the main processor, axis computer, I/O modules, and communication interfaces. The module ensures synchronized operation of all controller components by managing the timing and prioritization of inter-module communications.
The bus computer coordinates the real-time data flow necessary for precise robotic control, including motion commands, position feedback, I/O status, and system diagnostics. It implements the communication protocol that allows the main computer to send trajectory data to the axis computer and receive feedback from servo drives and I/O modules. The module’s robust design ensures reliable operation in industrial environments where electrical noise and vibration could disrupt communication integrity.

Core Features & Customer Value
The module’s high-speed communication capability ensures synchronized operation of all controller components, which is essential for precise multi-axis coordination in complex robotic applications. For manufacturing processes requiring tight tolerances and high path accuracy, this translates to consistent quality and reduced scrap rates. The deterministic communication timing enables predictable system performance, crucial for applications with strict cycle time requirements.
Advanced bus arbitration features manage communication priorities to ensure that time-critical data (such as servo commands and safety signals) receive preferential treatment over non-time-critical data. This design prevents communication bottlenecks that could affect motion smoothness or system responsiveness. For system integrators, this means reliable performance even in applications with extensive I/O and complex program logic.
The module’s comprehensive diagnostic capabilities monitor communication integrity and module health, providing early warning of potential issues. Maintenance personnel can use these diagnostics to identify communication errors or module failures before they cause unplanned downtime, supporting proactive maintenance strategies and improving overall system availability.
Typical Applications
In automotive spot welding applications, the DSBC172 ensures synchronized communication between the main computer (processing welding sequences) and the axis computer (contiding robot motion). The precise timing coordination enables perfectly synchronized weld gun operation as the robot moves between weld points, optimizing cycle times while maintaining quality.
In material handling applications with complex peripheral equipment, the bus computer manages data exchange between I/O modules controlling conveyors, vision systems, and grippers. The reliable communication ensures that pick-and-place operations are executed with precise timing, minimizing product damage and maximizing throughput.
