PLC is a programmable logic controller ( Micro Processor )
Application : All kind of industrial automation applications

How Does It Work :

As its programmable, Hence program is written ( LD/ST/FBD/IL/SFP langauges ) in line with the FDS ( Functional Design Requirement ) and on the basis of IO signals ( DI/DO/AI/AO ).

In each scan cycle PLC scans the IO status & accordingly process the logic.

SCADA :

Supervisory Control And Data Acquisition , is a graphical representation PLC logic Or Process

Modern PLC Brand :
