ABB Industrial Network and Backplane Integration

The DSQC658 provides a DeviceNet interface for exchanging cyclic and diagnostic data between the IRC5 controller and external nodes. Therefore, the board supports bus-based I/O communication instead of point-to-point discrete wiring.

DeviceNet uses CAN-based communication, while the available baud rates provide selectable network operating speeds. The installation must match the configured network baud rate and node settings.

In addition, the board uses status indicators to assist with power, module, and network diagnostics. Technicians can therefore identify basic communication conditions directly at the controller hardware.

The supplied data identifies the DSQC658 as a single Master/Slave DeviceNet interface. It does not specify redundant DeviceNet operation, hot-swap capability, or a defined backplane current load.

Frequently Asked Questions

Q: Can the DSQC658 operate as both a DeviceNet Master and Slave?
A: Yes. The supplied product designation identifies the unit as a DeviceNet Master/Slave Single interface.

Q: What DeviceNet communication speeds does the DSQC658 support?
A: The supplied specifications list 125 kbps, 250 kbps, and 500 kbps.

Q: Does the supplied data confirm hot-swap operation?
A: No. The supplied documentation does not specify hot-swap support. Treat the board as an internal controller component and follow the applicable IRC5 service procedure before removal or installation.

Field Installation Guidelines

• Isolate controller power before installing or removing the internal communication board.
• Verify the DSQC658 part number, board identification, and controller compatibility before installation.
• Route DeviceNet cabling separately from high-current motor and power wiring where practical.
• Maintain the DeviceNet cable shield and termination arrangement specified by the network design.
• Verify node addressing, baud rate, and network configuration before placing the controller into normal operation.
• Inspect connectors for correct seating and mechanical retention before energizing the controller.
• Use the front-panel diagnostic LEDs to check module and network status after startup.
• Do not assume hot-swap capability unless the applicable ABB IRC5 hardware documentation explicitly permits it.
