SCADA Systems (Supervisory Control and Data Acquisition Systems) have become integrated part of automated systems and have provided a greater degree of reliability along with increased efficiency to these tasks.

As clear from the name, itself SCADA systems are not any control systems but supervisory systems. They supervise automated tasks and take decisions on their own if any state/ parameter changes more than permissible value. Thus, these systems require minimal human intervention and can be addressed as closed loop systems. But human can intervene at any point of time, thus making these systems flexible to use.

The use of the SCADA systems, supplied through PACSNET in the Cement works industry makes radio the favorite and less expensive way of observing the utilities as well as outfalls. The system supplied by PACSNET has been used by many cement plants, realizing that cabled monitoring systems are impractical and more expensive than the wireless counterpart.

Some years ago, since legislations it has become a need to monitor onsite explosive stores as well as other key facilities for a 24 hour day. Radio would be the required technology for this use, and PACSNET is the best way out as the on air code of behavior and network organization techniques are well confirmed in the high defense applications.

PACSNET has been accepted by ACPO as well as many different Military bodies.

For both types of electricity management/ control systems (both traditional and nuclear), SCADA systems are employed these days. The role of SCADA in the electricity industry is same as SCADA systems play in other control systems.

These act as supervisory systems and they control the way the automated process is controlled. SCADA systems issues predefined response which is set through PLCs (Programmable Logic Circuits) when any parameter value/ state changes beyond permissible levels.

As human supervision is not feasible in this case, thus SCADA systems always prove to be reliable solution. The benefits of employing SCADA don't come to halt here. These systems store the collected data which prove beneficial for trouble shooting purposes. Without this available data, troubleshooting or locating fault in the circuits would have become a tedious task. The collected data gets stored in database which can be easily accessed for routine checks.
