Understand SCADA in One Minute

SCADA Basics: Definition

SCADA (Supervisory Control And Data Acquisition) is an automation remote monitoring and control system. As stated in its name, SCADA is applicable in any automation operation that requires supervisory control and real-time data acquisition. Whereby in this modern world, it is possible to use SCADA in any workplace/home, even though it was first introduced for industrial purpose.


SCADA Basics: Working Concept

SCADA basics

  • On the back-end, sensors will be connected to RTUs (Remote Terminal Units), or PLCs (Programmable Logic Controllers), where signals (such as meter reading and instrument status) will be converted to digital data.
  • To transport the digital data between RTUs/PLCs and control center, network connection media such as LAN or WAN will be used.
  • Data acquisition server shall be required for database storage purpose, as well as trend plotting and report generating.
  • On the front-end, these digital data will then be accessed by operator on HMI (Human-Machine Interface), where process control and monitor can be done. HMI can be on different platforms, from servers to tablets to even mobile phones.
