The ABB UFC762AE101 is engineered for robustness and scalability in modern automation, offering several key technological advantages:
· •Innovation Point 1: Scalable and Deterministic Performance: The UFC762AE101 is built to handle the most demanding control applications with a deterministic execution cycle. Its scalable computing power allows it to manage a large number of control loops and complex sequences efficiently, ensuring consistent and predictable performance even under heavy load, which is critical for process stability.
· •Innovation Point 2: Seamless System Integration via CEX Modules: A defining feature of the AC 800M platform is its use of Communication Extension (CEX) modules like the CI854A (for PROFIBUS) or CI871 (for Ethernet/IP). The UFC762AE101 seamlessly integrates with these modules, providing unparalleled flexibility to connect to a vast array of field devices and third-party systems without compromising the controller's core processing duties.
· •Innovation Point 3: High Availability and Robust Engineering: The controller is designed for high availability, supporting redundancy configurations when paired with a second UFC762AE101. Furthermore, it is programmed with ABB's Control Builder M software, which offers a powerful and standardized engineering environment for application development, simulation, and maintenance, significantly reducing lifecycle costs.
A major pulp and paper mill was upgrading its distributed control system to improve production efficiency and reduce unplanned downtime. The project centered on the ABB System 800xA platform with multiple ABB UFC762AE101 controllers managing different sections of the plant, from the digesters to the paper machines. The powerful processing capability of the UFC762AE101 allowed for the implementation of advanced model-based control strategies on the paper machine, resulting in a 15% reduction in grade change time and a 5% decrease in energy consumption. The reliability of the controllers led to a 40% reduction in control-system-related downtime in the first year of operation.
