For managing the manufacturing process there was the use of relays by the industries. It is said that there should be regular replacement of the relay control panels as there is excessive consumption of power and it is difficult to identify problems associated with it.

3. Define PLC?
For the automation of various electro-mechanical processes in
industries, a digital computer like Programmable Logic Controller
(PLC) is used. For dealing through tough times it has been designed in
such a way shielded from cold, heat, dust, and moisture etc. It is
programed using the computer language and is made up of micro-
processor.

7. 5. Power supply – There are some PLCs working at 220VAC
or 24VDC whereas certain PLCs have an isolated power supply.
6. Programming system – For feeding the program into the
memory of the processor this programing system is used. It is initially
fed to the programming device and later transmitted to the PLC’ s
memory.

8. 7. System Buses – Most of the internal signal flows through
the buses in PLC.
· CPU uses it to transfer data for different purposes.
· For controlling certain actions internally, control buses are used for
transferring signals

9. · For transferring the location’s address, address bus is used.
· I/O port and I/O unit communicates with each other with the help of
system bus.
