Supervisory Control & Data Acquisition


SCADA (Supervisory Control & Data Acquisition) systems are industrial and facility-based systems for monitoring and controlling processes in real time. SCADA systems are comprised of PLCs, RTUs, communication networks , HMIs and a database to offer a complete building management controlling operating system.

Application Overview

The objective of SCADA systems is to offer a comprehensive analysis of multiple processes and operations in real time with the ability to add in controls allowing changes or alterations to be made in real time. SCADA systems typically cover a varied or distributed database of elements and products which are grouped together via the PLC and have their progress illustrated via the HMI (Human-Machine Interface). Electrical systems and other processes that are sent to the PLC via RTUs (Remote Terminal Units) are connected via communication such as Modbus or at times Analog Output signals or Ethernet connectivity depending on the PLCs specification which allows the necessary information to be directly relayed.

SCADA Implementation

In electrical systems power meters and other metering devices are required to have a compatible communication and accurate RMS readings in order to seamlessly integrate with the PLCs and ultimately to the SCADA systems as a whole. Power meters with multiple communication protocols such as the Acuvim II series meters are imperative in SCADA systems as they ensure an effective communication between meter and PLC is formed.

The Acuvim II meters have Modbus RTU as inherent communication and are able to add communications extensions such as Profibus and analog output signals ensuring an easy connection to the leading PLCs currently in the market and with the flexibility to adapt to any upgrades.

Application Summary

SCADA systems are an integral component of building operations management and allow for process control for real time operational management. Meters such as Acuvim II series have multiple communication protocols that allow for a seamless connection between meter and PLC before contributing to the SCADA system as a whole.
