ABB DSQC679 Control Module
Product Overview
The ABB DSQC679 Control Module is a high-performance auxiliary control unit tailored for ABB industrial robot systems, specifically compatible with IRC5 and IRC5 Compact controllers. As a "functional extension hub" for robot control, it focuses on enhancing specialized control capabilities—including advanced motion synchronization, multi-device coordination, and high-precision sensor data processing—while offloading non-critical tasks from the main controller (e.g., DSQC639). Developed for complex industrial scenarios such as multi-robot collaborative operations, automated assembly with vision guidance, and precision material handling, this module supports up to 8 auxiliary axes (for external axes like conveyors or positioners) and integrates dedicated logic for real-time task scheduling. It features a compact, rugged design with robust anti-interference performance, enabling stable operation in harsh environments with electromagnetic interference (e.g., welding cells) or temperature fluctuations (-30℃ to +65℃). With seamless compatibility with ABB RobotStudio software and standard industrial communication protocols, the DSQC679 Control Module simplifies system integration, improves control flexibility, and serves as a key component for building scalable, multi-functional robot workcells.
Structural Features
- Dual-Core Auxiliary Processor: Equipped with a 32-bit dual-core industrial-grade processor (main frequency 800MHz), including a dedicated axis control core and a sensor data processing core. The axis control core manages up to 8 auxiliary axes with a motion cycle time of 2ms, supporting synchronized motion with the main robot (e.g., conveyor tracking, positioner coordination) and ensuring trajectory deviation ≤0.2mm. The sensor data processing core handles high-speed input from vision systems (up to 1000 frames/sec) and force torque sensors (1kHz sampling rate), enabling real-time adjustment of robot motion based on environmental feedback—critical for adaptive assembly tasks.
- Modular Expansion and Connection Interface: Features a high-speed backplane interface (500Mbps) for direct connection to ABB main controllers (DSQC639) and compatible I/O modules (e.g., DSQC651 digital I/O, DSQC652 analog I/O). It includes 4×M12 connectors for sensor/actuator wiring (supporting Power over Ethernet, PoE) and 2×USB 2.0 ports for local configuration. Additionally, the module supports daisy-chaining of up to 4 DSQC679 units via a dedicated synchronization bus, enabling control of up to 32 auxiliary axes for large-scale applications (e.g., multi-robot assembly lines).
- Dual-Channel Memory Design: Integrates 128MB DDR4 RAM (with ECC error correction) for real-time data caching, ensuring integrity of motion parameters and sensor data during high-speed operations. It also includes 64GB industrial-grade eMMC storage (with wear leveling) for storing auxiliary control programs, calibration data, and log files—reducing reliance on the main controller’s storage and enabling independent operation during main controller maintenance. A 4MB non-volatile memory (NVM) retains critical parameters (e.g., axis calibration data) for up to 6 months without power.
- Protection and Durability
- Reinforced EMC Shielding: The module’s casing is made of galvanized steel with a conductive epoxy coating, and the internal circuit board adopts a 4-layer PCB design with separate power and signal planes. This shielding design complies with EN 61000-6-2 (industrial immunity) and reduces EMI emissions by 40%, ensuring stable operation near high-voltage welding equipment, frequency converters, or other EMI sources in automotive or manufacturing facilities.
- Harsh Environment Adaptability: The power supply circuit supports 24V DC (±15%) input, with built-in overcurrent (3A), overvoltage (30V), and reverse polarity protection. The operating temperature range of -30℃ to +65℃ (with short-term operation up to +70℃) allows deployment in cold storage, foundries, and outdoor semi-enclosed work areas. The circuit board is coated with a 0.1mm-thick polyurethane conformal coating, resisting moisture (relative humidity 5%–95%, non-condensing), oil mist, and mild chemical vapors (e.g., cleaning solvents).

- Expansion interfaces: 1×synchronization bus port (for daisy-chaining), 1×PCIe Mini slot (for vision/force sensor cards).
- Real-time communication latency: ≤2ms (Profinet RT), ≤15ms (Modbus TCP/IP), ≤1ms (synchronization bus).
- Complies with EN ISO 13849-1 (SIL 1, PL c) for functional safety.
- Built-in safety functions: Safe stop 1 (SS1), safe speed monitoring (SSM) for auxiliary axes, and safe input/output (safe I/O) for emergency stops.
