SCADA

aid: scada
name: SCADA
description: SCADA (Supervisory Control and Data Acquisition) is an industrial control system architecture used to monitor
  and control industrial processes, infrastructure, and facility-based equipment. It is widely used in manufacturing, energy,
  water treatment, oil and gas, transportation, and other critical infrastructure sectors to collect real-time data from remote
  sensors and control equipment. Modern SCADA systems increasingly expose REST APIs, OPC-UA endpoints, and MQTT brokers for
  integration with enterprise systems, cloud platforms, and AI/ML workloads.

  name: OPC Unified Architecture (OPC-UA)
  description: OPC-UA (IEC 62541) is the industrial interoperability standard for secure, reliable data exchange in industrial
    automation and IoT environments. It provides a platform-independent, service-oriented architecture for accessing real-time
    and historical data from PLCs, sensors, and SCADA systems. OPC-UA supports both client/server and pub/sub communication
    models.

  name: MQTT Protocol
  description: MQTT (Message Queuing Telemetry Transport, ISO/IEC 20922) is a lightweight pub/sub messaging protocol widely
    used in SCADA and IIoT applications for sensor data collection and device control. MQTT brokers (Mosquitto, EMQX, HiveMQ)
    are commonly deployed in SCADA architectures for real-time telemetry streaming.

  name: Modbus Protocol
  description: Modbus is a serial communication protocol widely used in industrial automation and SCADA systems for connecting
    electronic devices. Modbus TCP/IP enables integration over standard Ethernet networks, making it one of the most common
    field device protocols in SCADA deployments.

  name: Historian and Alarm Data APIs
  description: SCADA historians store time-series process data for analysis, reporting, and compliance. Major historian vendors
    (OSIsoft PI, Aspen InfoPlus.21, GE Proficy Historian) expose REST APIs for querying historical process data. The OSIsoft
    PI Web API provides a RESTful interface to PI System data assets.
