Applications of scada

Across industries such as food & beverage processing, pharma, biotech, water/wastewater management, energy management, refrigeration, HVAC & building management, electricity transmission & distribution and more, the application of SCADA in the industry is widespread. First used in the 1960s. SCADA systems are now an integral component in virtually all industrial plant and production facilities. Let's discuss SCADA in some detail.

WHAT IS SCADA?

SCADA stands for Supervisory Control and Data Acquisition. SCADA is a computer-based system for gathering and analyzing real-time production data, monitor and manage alarms, and program automatic responses triggered by certain events or system parameters.

It is also able to operate in a cloud environment so that SCADA monitoring and control can be accomplished remotely by using tablets and smartphones.

WHAT ARE THE FUNCTIONS OF SCADA?

The SCADA system of software and hardware enable:

• automated control and management of industrial processes & machines in real-time from a remote location
• data collection and analyses
• event and alarm notifications
• report generation
• historical data logging, archiving and retrieval

WHAT ARE THE KEY COMPONENTS OF A SCADA SYSTEM?

A typical SCADA system utilizes Distribution Control Systems (DCS), Process Control Systems (PCS), Programmable Logic Controller (PLC), and Remote Terminal Units (RTU).

To perform its functions, SCADA integrates with sensors and other measuring devices (digital or analog) to collect data. The collected data is sent to the RTU or PLC to be translated into usable information. Finally, the information is relayed to the HMI (Human Machine Interface) or other types of display for operators to analyze and respond.

HOW CAN SCADA HELP ME?

SCADA applications in your facility provide useful production insights to operators and management to help decrease production waste and enhance overall efficiency. The information from a SCADA system enables data-driven decisions that lead to increased output, greater control of processes and reduced costs.

Secondly, with instant notification and alarms, operators and backup systems are able to respond faster to events and manage critical machine failure in real-time, thereby reducing equipment/process downtime and wastage.

SCADA automates common, tedious, routine tasks once performed by a human; precise machine control for monitoring equipment and processes virtually eliminates human error.

Moreover, SCADA systems in a large geographical displacement where an organization may not have enough manpower to cover, SCADA systems facilitate monitoring and control.
