## Overview

Rapid SCADA is a distributed industrial automation platform for monitoring and control. The main operator workflow is field-device data acquisition, server-side processing, and delivery of current, historical, and event data through web APIs; commands travel back toward devices. Administrators configure projects and communication, server, and web modules, and can deploy configurations to instances. The README also describes multi-node operation and real-time external database interaction. Sampled code confirms API calls, OPC UA command dispatch, and storage behavior; other subsystem links are based on the documented product workflow and tree.

Main entry points: [`ScadaServer/ScadaServer/ScadaServerEngine`](https://github.com/rapidscada/scada-v6/tree/master/ScadaServer/ScadaServer/ScadaServerEngine) (SCADA server), [`ScadaAdmin/ScadaAdmin/ScadaAdmin/Forms/FrmMain.cs`](https://github.com/rapidscada/scada-v6/blob/master/ScadaAdmin/ScadaAdmin/ScadaAdmin/Forms/FrmMain.cs) (SCADA Admin), [`ScadaWeb/OpenPlugins/PlgMain/Controllers/MainApiController.cs`](https://github.com/rapidscada/scada-v6/blob/master/ScadaWeb/OpenPlugins/PlgMain/Controllers/MainApiController.cs) (Web data API), [`ScadaCommon/ScadaCommon/Storages/StorageLogic.cs`](https://github.com/rapidscada/scada-v6/blob/master/ScadaCommon/ScadaCommon/Storages/StorageLogic.cs) (Storage abstraction)
