ABB DSQC378B Communication Module
Product Overview
The ABB DSQC378B communication module is a dedicated industrial communication component designed for ABB industrial robots, specifically tailored to enhance the data interaction capabilities of ABB robot control systems (such as IRC5 and IRC5 Compact controllers). As a "communication bridge" between robots and external automation devices, it enables seamless data transmission and command interaction between robots and upper-level control systems (SCADA, MES), peripheral smart equipment (sensors, vision systems), and fieldbus networks. Developed for high-reliability industrial scenarios—including automotive manufacturing, electronic assembly, and logistics automation—this module supports multiple mainstream industrial communication protocols, ensuring stable connectivity even in complex electromagnetic environments (e.g., near welding robots or high-voltage motors) and frequent robot motion cycles. It integrates robust anti-interference design and plug-and-play compatibility, reducing deployment time while guaranteeing real-time and accurate communication for robot-centric automated production lines.
Structural Features
- Multi-Protocol Integration Architecture: The module adopts a modular protocol processing chip design, integrating dedicated hardware cores for Profinet, Ethernet/IP, and Modbus TCP/IP protocols. This hardware-based protocol processing reduces the load on the robot controller’s main CPU (by up to 40% compared to software-emulated communication) and ensures deterministic communication latency (≤10ms for cyclic data exchange), critical for synchronized operations like robot-conveyor coordination.
- Dual Ethernet Ports with Redundancy: Equipped with two 10/100Mbps Ethernet ports (RJ45 interfaces) supporting network redundancy. In redundant network mode, if the primary port fails (e.g., cable disconnection), the module automatically switches to the backup port within 50ms, avoiding communication interruptions that could halt production. The ports also support Auto-MDI/MDI-X, eliminating the need for crossover cables and simplifying on-site wiring.
- Compact and Robot-Mounted Form Factor: With dimensions of 85mm (W) × 120mm (H) × 35mm (D) and a weight of 180g, the module is designed for direct mounting on ABB robot control cabinets (via DIN rail or screw fixing) without occupying additional floor space. The front-facing interface layout (Ethernet ports, status LEDs, configuration buttons) allows easy access for wiring and troubleshooting, reducing maintenance time.
- Protection and Reliability
- EMC Shielding: The module’s metal casing features a nickel-plated electromagnetic shielding layer (compliant with EN 61000-6-2), which reduces EMI emissions by 35% and provides immunity to external interference (e.g., from welding arcs or motor drives). This ensures stable communication in electromagnetic-dense environments common in automotive body shops.
- Wide Voltage and Temperature Tolerance: The power supply circuit supports 24V DC (±15%) input, with built-in overcurrent (1A) and overvoltage (36V) protection to withstand voltage fluctuations in industrial power grids. The operating temperature range of -25℃ to +60℃ (with derating up to +70℃ for short periods) allows deployment in both cold storage logistics and high-temperature manufacturing workshops.
Technical Parameters

- Ethernet/IP: Supports DLR (Device Level Ring) for network redundancy; complies with ODVA specifications for explicit/implicit messaging; maximum implicit message size of 512 bytes.
- Modbus TCP/IP: Supports client/server modes; maximum register read/write rate of 100 registers per request; compatible with Modbus TCP/IP V1.1.
- Ethernet port speed: 10/100Mbps (auto-negotiation); full-duplex mode supported.
- Maximum number of concurrent connections: 8 (4 Profinet, 2 Ethernet/IP, 2 Modbus TCP/IP).
- Cyclic data latency: ≤10ms (IRT mode), ≤50ms (RT/Modbus TCP/IP modes).
- Local configuration: Via front-panel push buttons + 4-digit LED display (for IP address setting) or USB port (for firmware updates).
- Remote configuration: Via ABB RobotStudio software (v6.0 or later) or web-based management interface (HTTP/HTTPS), supporting parameter backup/restore and protocol-specific settings (e.g., Profinet device name, Ethernet/IP DLR ring priority).
- Electrical and Physical Parameters
- Power Consumption: Typical 3.2W (under full load), maximum 4.5W (during firmware updates).
- LED Indicators: 6 status LEDs (power, Profinet link/activity, Ethernet/IP link/activity, Modbus TCP/IP link/activity, error) with color-coded feedback (green: normal, yellow: warning, red: fault) for quick status identification.
- Safety: UL 508, CSA C22.2 No.14, IEC 61508 (SIL 1 for functional safety).
- EMC: EN 61000-6-2 (immunity), EN 61000-6-4 (emissions).
- Environmental: RoHS 2.0 (restriction of hazardous substances).
