Product Overview

The PU519, identified by part number 3BSE018681R1, is a high-performance Real-Time Accelerator (RTA) board designed for the ABB System 800xA and Advant OCS architectures. This specialized hardware serves as a dedicated communication co-processor, offloading time-critical network tasks from the main controller CPU to ensure deterministic system behavior. By providing a high-speed interface for Advant Fieldbus 100 (AF100) and other proprietary control networks, the PU519 enables millisecond-level data synchronization across large-scale Distributed Control Systems (DCS). It is an essential component for installations requiring rapid signal arbitration and high-bandwidth data throughput between controllers and operator workstations.

Strategic Deployment and Operational Utility

The PU519 RTA board is a vital asset for automation infrastructures where communication latency must be virtually non-existent to maintain process safety and efficiency.

• AF100 Network Acceleration: Acts as the primary gateway for Advant Fieldbus 100, ensuring that process variables are updated at maximum bus speeds.

• Controller-to-HMI Synchronization: Facilitates the rapid transfer of high-volume process data to 800xA Aspect Servers, providing operators with real-time visualization of plant conditions.

• Large-Scale DCS Integration: Used in complex facilities like oil refineries or power plants to manage communication between multiple AC 800M or AC 450 controllers.

• System Upgrades and Expansions: Provides a necessary performance boost for legacy Advant systems being integrated into modern System 800xA environments.

• Deterministic Event Handling: Enables high-precision Sequence of Events (SOE) recording by minimizing the jitter and delay typically associated with standard network interfaces.
