About Godrej
Godrej Group is one of the largest conglomerates based in Mumbai, India, involved invarious industries that include appliances, precision equipment, machine tools, furniture,
healthcare, interior solutions, office equipment, food-processing, security, materials handling and
industrial storage solutions, construction and information technology. Its products include
security Systems and Safes, Typewriters and Word processors, Rocket Launchers, Refrigerators
and Furniture, Outsourcing Services, Machine Tools and Process Equipment, Cosmetics and
Detergents, Engineering Workstations, Medical Diagnostics and Aerospace Equipment, Edible
Oils and Chemical, Mosquito Repellents, Car perfumes, Chicken and Agri-products, Material
Handling Equipments Like FORKLIFT Trucks, Stackers, Tyre handlers, Sweeping machines,
access equipments etc. The Group is headed by Adi Godrej and Jamshyd Godrej.
Traditionally, Vikhroli, a suburb to the Northeast of Mumbai has been Godrej's
manufacturing base, but increasingly the group have moved significant production facilities
away from Mumbai. The Godrej group also owns vast land in Vikhroli, occupying 3500 acres
(14 sq km) of land on both sides of the Vikhroli section of the LBS marg. That makes the Godrej
group the biggest private land owner in Mumbai by far. Such vast land can, in theory, be used tocreate at least 1,500 acres (6.1 km2) of residential floor space, which, at very modest rates
(Rs.10000/sq ft), can be sold for USD 16 billion.

where software revision replaced the re-wiring of hard-wired control panels when production
models changed.
Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles
was accomplished using hundreds or thousands of relays, cam timers, and drum sequencers anddedicated closed-loop controllers. The process for updating such facilities for the yearly model
change-over was very time consuming and expensive, as electricians needed to individually
rewire each and every relay.
Digital computers, being general-purpose programmable devices, were soon applied to control of
industrial processes. Early computers required specialist programmers, and stringent operating
environmental control for temperature, cleanliness, and power quality. Using a general-purpose
computer for process control required protecting the computer from the plant floor conditions.
An industrial control computer would have several attributes: it would tolerate the shop-floor
environment, it would support discrete (bit-form) input and output in an easily extensible
manner, it would not require years of training to use, and it would permit its operation to be
monitored. The response time of any computer system must be fast enough to be useful for
control; the required speed varying according to the nature of the process.
In 1968 GM Hydramatic (the automatic transmission division of General Motors) issued a
request for proposal for an electronic replacement for hard-wired relay systems. The winning
proposal came from Bedford Associates of Bedford, Massachusetts. The first PLC, designated
the 084 because it was Bedford Associates' eighty-fourth project, was the result. Bedford
Associates started a new company dedicated to developing, manufacturing, selling, and servicing
this new product: Modicon, which stood for MOdular DIgital CONtroller. One of the people who
worked on that project was Dick Morley, who is considered to be the "father" of the PLC. The
Modicon brand was sold in 1977 to Gould Electronics, and later acquired by German Company
AEG and then by French Schneider Electric, the current owner.

alo easy to change when the comtrol problem changes and allows many more logical functions
that are possible with hardwired logic control. When reliable microprocessors are available in

One of the very first 084 models built is now on display at Modicon's headquarters in North
Andover, Massachusetts. It was presented to Modicon by GM, when the unit was retired after
nearly twenty years of uninterrupted service. Modicon used the 84 moniker at the end of its
product range until the 984 made its appearance.
The automotive industry is still one of the largest users of PLCs.
Programmable logic controller
Introduction
A programmable logic controller (PLC) or programmable controller is a digital computer used
for automation of electromechanicalprocesses, such as control of machinery on factory assembly
lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike
general-purpose computers, the PLC is designed for multiple inputs and output arrangements,
extended temperature ranges, immunity to electrical noise, and resistance to vibration and
impact. Programs to control machine operation are typically stored in battery-backed or non-
volatile memory. A PLC is an example of a hard real time system since output results must be
produced in response to input conditions within a bounded time, otherwise unintended operation
will result
Early PLCs were designed to replace relay logic systems. These PLCs were programmed in
"ladder logic", which strongly resembles a schematic diagram of relay logic. This program
notation was chosen to reduce training demands for the existing technicians. Other early PLCs
used a form of instruction list programming, based on a stack-based logic solver.
