PLC and SCADA Automation:

• A PLC (i.e. Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. The PLC works by looking at its inputs and depending upon their state, turning on/off its outputs. The user enters a program, usually via software, that gives the desired results. PLCs are used in many "real world" applications.

• This is widely used in industry for Supervisory Control and Data Acquisition of industrial processes. SCADA systems are now used in the controls of ancillary systems such as cooling, ventilation, power distribution, etc. and have made substantial progress over the recent years in terms of functionality, scalability and performance.
