HCS SCADA, an original Supervisory Control and Data Acquisition System for electric measurement and control application.
The configuration is based on the RTU (Remote Terminal Unit) and DTU (Distributed Terminal Unit) products developed, also configured with many kinds of measuring devices and local supervisory controlcomputer, totally under through HC technology. HCS SCADA featuring data-processing capability aspowerful and efficient as traditional RTU and increasing capability of communication, also complying with absolute relay cyber-protect unit. HCS SCADA providing a very flexible solution of data acquisition and Control in the Substation site.
HCS SCADA providing various and excellent functions as well as a Substation Automation System and Distribution Automation System and in general industrial PLC system for total data acquisition and data control automations.

Purpose :

  • As data-acquisition and control terminal equipment in all different levels of transformer substation.
  • As data-acquisition and control terminal equipment for power automatic application in factory.\

    Advantage :

  • Multi-processor and distributed structure
  • Support dual CPU coordination work.
  • Modular designed structure, keeping maintenance and expansion easily
  • Support multi-hosts and multi-channels
  • Support multi-protocols
  • Support multi-channels for intelligent electronic devices
  • Support programming logical control (HC Ladder Diagram)
  • Support high-accuracy and highresolution in Sequence-of-Event Report



    • Real-time data acquisition and processing
    • Calculated numerals data processing
    • Control operation
    • Communicating to hosts and transferring data to sub-control center
    • Record for Sequence of Event

    • Reports management and print-out
    • Self-diagnosis and self-restart
    • Maintenance and monitoring locally and remotely
    • GPS clock auto-adjustment

    According to the request of customer and circumstance in the field, HCS SCADA can provide two different kinds of system configuration. Which are of concentrated cabinet style and distributed style, to satisfy the different customers requirement. Concentrated enclosure type The concentrated configuration is based on the RTU units. All signals that come from the fields shall be sent to the RTU unit through the cable. Featuring as the center of the data acquisition and control, RTU unit process these data information and communicate to the host unit, include remote host and local host. Properly performed in newly-build substations or reconstructive substations which needs big-amount also needs many concentrated equipments requirement. The detailed diagram is as listed below :
