800xA Simulator Manual

This document describes ABB's 800xA Simulator, a standalone automation system that replicates a running plant's control logic, operator interfaces, and I/O to provide a safe, realistic environment for operator training, engineering verification, and process optimization. It connects to a dynamic process model via OPC DA and COM interfaces, supports multiple ABB control systems (e.g., AC 800M, Symphony), and offers features like save/load of process states, freeze/resume, and faster/slower-than-real-time simulation.
