Product Overview

The ABB DSQC 351A / DSQC 351B  circuit board actively manages input and output signals between DeviceNet systems and INTERBUS systems. Typically, it mounts inside the control module, but it can also integrate into an external I/O device for flexible deployment. This board ensures reliable communication and seamless data exchange in industrial automation networks.

Key Features

Communication Support:
The DSQC 351 supports multiple connection types to handle I/O messages efficiently:

• Polled: Each slave receives a query from the master and responds before the next device is queried.
• Change-of-State: Transmits data only when a state changes.
• Change-of-State with Acknowledge Suppression: Reduces communication overhead by suppressing acknowledgement messages.

Baud Rate:
The board operates at 500 Kbps, ensuring high-speed communication between devices.

I/O Message Handling:
It facilitates different types of I/O connections:

• Polled Connection: Suitable for any amount of I/O data. The master sends requests, and each slave responds individually.
• Strobe Connection: Enables quick multicasting of small data amounts. The master sends one message to all slaves, resulting in synchronized readings.
