ABB 3HNE00421-1 DSQC378B CC-Link Communication Module for Robot Controllers

DSQC378B CC-Link Communication Module for ABB Robot Controllers

Specifications

Industrial Applications

• Automotive welding and assembly lines integrating ABB robots with Mitsubishi PLCs via CC-Link.
• Electronics, LCD and semiconductor lines requiring robot-to-CC-Link network data exchange.
• Battery manufacturing and material-handling cells built on a multi-vendor CC-Link fieldbus.
• General ABB robot cells requiring CC-Link fieldbus connectivity to the plant network.

Design Purpose

The DSQC378B (3HNE00421-1) is the CC-Link interface module for an ABB robot controller. It converts and routes communication between the controller's internal DeviceNet bus and an external CC-Link network, letting the robot act as a node that exchanges I/O and process data with CC-Link master stations such as Mitsubishi PLCs. Because the module sits on both the controller's option bus and the plant CC-Link network at the same time, correct station numbering and baud-rate matching are essential — a mismatch can drop the robot from the cell network and halt coordinated motion.

Common Failure Modes

• CC-Link terminal (X8) screws loosening from cabinet vibration, causing intermittent communication.
• Station-number or baud-rate mismatch after replacement, leading to node offline or address conflict.
• ESD or surge damage to the communication chips.
• Connector pin bending or corrosion from poor contact.
• Firmware or parameter loss after a controller swap, so CC-Link is not recognized.
• LED fault from 24 V power loss at the communication interface.
