A PLC Programmable logic controller is a solid state user programmable control system with a function to control logic, sequencing, timing, arithmetic data manipulation and counting capabilities. It can be viewed as an industrial computer that has a central processor unit, memory, input/output and a programming device.
FEATURE: PLCs are evolving and continue to be the best option for a variety of industrial automation applications. Greater programming flexibility and easy, scalability, more memory, smaller sizes, very high-speed communication on different networking.
APPLICATION: PLCs are used more and more as a total solution to a batch process in chemical, cement, food and paper industries are sequential in nature, requiring time or event-based decisions.
A SCADA supervisory control and data acquisition is an industrial control system which is used in many modern industries like energy, manufacturing, power, transportation etc. SCADA systems organize multiple technologies that allows processing, gather and monitor data at the same time to send an instruction to those points that transmit data.
FEATURE: SCADA system improves the overall efficiency of the system for optimizing, supervising and controlling of the industrial process control system.
APPLICATION: In todayâ€™s world, almost anywhere you can observe SCADA system, whether it’s a wastewater treatment plant, supermarket, industries or even in your home.
