3.  Developed to replace relays in the late
1968s.
 Costs dropped and became popular by
1980s.
 Now used in many industrial designs.
Leading Brand
Allen Bradley, General Electric, Siemens,
Toshiba, GE Fanuc, Omron etc.

4.  Less Wiring .
 Wiring between devices and relay
contacts are done in the PLC program.
 Easier and Faster to make change.
 Trouble shooting aids make
programming easier and reduce
downtime.

7.  Power supply – provides the voltage
needed to run the primary PLC
components.
 I/O Modules – provides signal conversion
and isolation between the internal logic-
level signals inside the PLC and the field’s
high level signal.

8.  Processor – provides intelligence to
command and govern the activities of the
entire PLC system.
 Programming devices – used to entire the
desired program that will determine the
sequence of operation and control of
process equipment or driven machine.

14. Supervisory Control And Data Acquisition
(SCADA)
• A SCADA system is a common industrial process automation
system which is used to collect data from instruments and
sensors located at remote sides and to transmit data at a
central site for either monitoring or controlling purpose.
• The collected data from sensor and instruments is usually
viewed on one or more SCADA host computer that are
located at the central site.
