4. Plc is a semiconductor device. Which is use for controlling
Any industrial process.
Plc is combination of hardware and software.
PLC is a digital computer designed for multiple inputs
and outputs arrangements.
A PLC is a example of real time system.
7. PLC was introduced in year 1960’s
First PLC was designed and developed by
MODICON as a relay replacer for general
motors.
Earlier it was a machine with thousands of
electronic parts.

14. The ladder logic is the oldest programming language for PLC.
It is well suited to express combinational logics.
The main ladder logic symbol represent the elements.
17. Advantage of plc:
Reliability.
Reduced space.
Energy saving.
High speed of operation.
Shorter project time.
Disadvantages of PLC:
Fixed ckt operation.
Limited design and cost of operation.
PLCs manufactures offer only closed architectures.
18. Few examples of industries where PLC is used:
1) Robots manufacturing and control.
2) Car park control.
3) Food processing.
4) Materials handling
5) Machines tools.
6) Conveyer system.
