Product Overview

The ABB PU515, part number 3BSE013063R1, is a specialized Real-Time Accelerator (RTA) board designed for the System 800xA distributed control architecture. This high-speed communication interface is engineered to offload time-critical tasks from the host workstation's CPU, ensuring deterministic and low-latency data exchange between the operator station and the Advant Fieldbus 100 (AF100) network. By acting as a dedicated processing bridge, the PU515 ensures that process values, alarms, and control commands are synchronized in true real-time, preventing network jitter and enhancing the overall stability of the human-machine interface (HMI) in complex industrial environments.
