Robot Module | DSQC 378B 3HNE00421-1 | ABB

Technical Specifications

The DSQC 378B units offer an interface between the CCLink bus and the DeviceNet Lean bus as used on the robot system. The units are regarded as intelligent devices by the CCLink PLC. ept The CCLink can communicate with a number of external devices, depending on
the number of stations occupied by each unit. There is a maximum of 64 stations, each capable of up to 32 I/O points and 8 points word data. The units are setup to have between 1 and 4 occupied stations each. 

Troubleshooting & Comissioning Checklist

Terminal Resistors: Verify that a standard 110Ω (or 130Ω depending on the cable type) terminating resistor is wired between the DA and DB lines at both physical ends of the CC-Link network segment.
Signal Lines: Double-check that DA, DB, DG (Digital Ground), and SLD (Shield) are wired to the correct terminals on the network connector block.
Grounding: Confirm that the shield line (SLD) is grounded at one single point on the network to prevent ground loops.

Field Engineering Considerations

Protocol Bridging: The device acts simultaneously as a DeviceNet Slave to the ABB robot controller and a CC-Link Remote Device Station to the factory PLC.
Data Mapping: Data bytes must be meticulously mapped between the CC-Link station registers and the DeviceNet I/O image within the ABB IRC5 or S4C+ controller.
Power Supply: The module requires a stable 24V DC industrial power source. Ensure that the ground reference for the 24V supply matches the network specifications to prevent ground loops.

Technical FAQ

Q: What is the primary function of the DSQC 378B?
A:It acts as a protocol bridge between a CC-Link network (typically used by Mitsubishi PLCs) and the internal DeviceNet network of the ABB robot system. It allows high-speed, seamless data exchange between the robot controller and the master PLC.

Q: How is the module detected by the system?
A: The device acts as a standard DeviceNet slave on the robot controller's internal network. 

Q: Can the DSQC 378B act as a Master on the CC-Link network?
A:No. The DSQC 378B functions strictly as a Remote Device Slave to the primary PLC. It cannot scan or manage other slave modules on the CC-Link network on its own.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
