ABB BRC-300 Bridge Controller and Process Bus Adapter

ABB BRC-300 Bridge Controller and Process Bus Adapter

The Harmony Bridge Controller (BRC-300) is a high-perfor mance, high-capacity process controller. It is a rack controller designed to interface with both Harmony block I/O and Har mony rack I/O in the Symphony™ Enterprise Management and Control System. 

The controller is fully compatible with the INFI 90® OPEN system in functionality, communication and packaging. 

The controller collects process I/O, performs con trol algorithms and outputs control signals to process level devices. 

It also imports and exports process data of other con trollers and system nodes, and accepts control commands from operators and computers connected to the network. 

This instruction provides information about how the controller works, and how to install, configure, operate and troubleshoot the controller.

The controller is designed for redundancy (two controllers needed). 

This can be achieved while remaining connected to the Hnet or not

Performance Benefits

Powerful interface capabilities: 

Seamlessly interfaces with Harmony Block I/O and Harmony Rack I/O within the Symphony™ enterprise management and control system, 

and is fully compatible with the Infi 90® open system in terms of functionality, communications, and packaging.

Comprehensive data processing and control capabilities: Collects process I/O data, performs various control algorithms, 

and outputs control signals to process-level devices. At the same time, it can import/export process data from other controllers and system nodes, 

and receive control commands from networked operators and computers.

Excellent hardware performance: 160MHz microprocessor with various types of memory ensures high-speed data processing and storage; 

supports various communication methods such as Hnet communication, I/O expansion bus, serial channel and station link; 

with redundant design, redundant controllers are connected through cables, 

and the control can be switched seamlessly in the event of the main controller failure.

Rich language support: support for a variety of control languages, including C language and function code (FC), 

which is convenient for engineers to develop according to different application scenarios and programming habits.

Precautions

Installation environment: 

It should be installed in a dry, well-ventilated environment where the temperature and humidity are in line with industrial standards to avoid dust, 

corrosive gases, etc. affecting the performance and life of the equipment.

Redundancy Configuration: 

In redundancy configuration, it is necessary to ensure that the configuration of the two redundant modules is identical, 

otherwise it may lead to switching anomalies and other problems.

Communication connection: 

When connecting with other devices, wiring should be carried out in strict accordance with the interface specifications 

nd cable requirements to prevent communication failures caused by wiring errors.

Software programming: 

When writing the control programme, the resource limitations of the controller should be fully considered, 

so as to avoid overly complex procedures leading to too high a load on the controller and affecting the real-time control performance.
