SCADA System
A SCADA system comprises industrial PLC controllers, distributed I/O modules, HMI interfaces, and data servers, integrating real-time data acquisition (≥100ms frequency), dynamic process visualization, alarm management (response ≤500ms), and remote control. Supporting Modbus/OPC UA protocols, it features EMI resistance (EN 61000 compliant), dual-machine hot standby (switching ≤200ms), and edge computing. It operates by collecting field data via sensor networks, transmitting through communication networks to central processors for equipment monitoring and parameter optimization. Applied in power grid dispatching, oil-gas pipelines, water treatment plants, and smart manufacturing lines, complying with IEC 61784 industrial communication standards.
