What is PLC/SCADA/DCS ?

PLC is a programmable Logic controller which is used mainly for interlocking different equipments.

DCS is Distributed Control Systems which is used to control very big plants by using simple GUI screens. PLCs are interfaced with DCS for interlocking.

SCADA is Supervisory Control and Data Aquisition which is used to control and Monitor small number of Equipments in a field.SCADA systems are typically used to perform data collection and control at the supervisory level. Some systems are called SCADA despite only performing data acquisition and not control.The supervisory control system is a system that is placed on top of a real-time control system to control a process that is external to the SCADA system (i.e. a computer, by itself, is not a SCADA system even though it controls its own power consumption and cooling). This implies that the system is not critical to control the process in real time, as there is a separate or integrated real-time automated control system that can respond quickly enough to compensate for process changes within the time constants of the process

PLC & SCADA Based Industrial Automation 

The systems are based on different programming software including Visi- Windows, Genesis and Intellution. These systems helps in making the process automatic without any human intervention that in turn also eliminates the possible human errors. The automation of systems makes the whole process accurate with less material wastage and consistent product quality. 

The process data is recorded continuously batch wise, line wise and equipment wise and can be shared by using SQL ERP System. This data helps in conducting yield analysis, production rate productivity and material & manpower usage. It also send text messages to the concerned staff in critical situations. It is managed using Distributed Computing architecture (DCS).
