SCADA System for Industrial Process Control

Product Specifications

Technical details and manufacturing context for Supervisory Control and Data Acquisition

Definition

SCADA (Supervisory Control and Data Acquisition) is a component of process control systems used in machinery and equipment manufacturing. It provides centralized monitoring, control, and data acquisition for industrial processes. The system collects real-time data from remote field devices such as sensors and actuators, transmits it to a central computer via communication networks, and presents it to operators through human-machine interfaces (HMIs). Operators can then send supervisory control commands back to field devices to adjust process parameters. SCADA systems typically include remote terminal units (RTUs) or programmable logic controllers (PLCs) for data acquisition, communication modules for data transfer, and operator workstations for visualization and control. The system supports various communication protocols, including Modbus TCP/RTU, and may optionally support OPC UA. It operates within specified parameters such as an operating pressure of 1.0–1.6 MPa, an operating temperature range of -20 to 85 °C, and an input voltage of 24 V DC ±10%. Power consumption ranges from 15 to 30 W for typical 10-inch HMI configurations. The number of I/O points is expandable via modules, ranging from 32 to 256 points. Sampling rates are configurable per channel, from 10 to 1000 Hz, with an accuracy of ±0.1% FS for analog inputs (per IEC 60770). The system offers ingress protection ratings from IP54 to IP65 (per IEC 60529) for panel-mounted units, and operates in non-condensing humidity of 10–90% RH. Weight varies from 5 to 15 kg depending on configuration, and display sizes range from 7 to 21 inches with optional touchscreen. These values are directory reference ranges and must be verified with the legal manufacturer or supplier for specific models and applications.

Working Principle

SCADA systems operate by collecting data from sensors and field devices through remote terminal units (RTUs) or programmable logic controllers (PLCs). This data is transmitted to a central computer via communication networks, where it is processed and displayed on operator workstations. Operators can then send control commands back to field devices to adjust process parameters. The system relies on communication protocols such as Modbus TCP/RTU, and optionally OPC UA, to ensure reliable data exchange. The central computer continuously polls or receives data from field devices, updates the HMI in real time, and logs historical data for analysis. Control commands are transmitted from the operator workstation to the field devices, enabling supervisory control. The system's performance is influenced by parameters such as sampling rate, accuracy, and communication latency. Proper configuration of these parameters is essential for effective monitoring and control.
