Introduction
Progress in industrial automation has helped industry to increase its productivity
and lower its costs.Widespread use of electronics and powerful, flexible software
have given rise to more efficient modular designs and new maintenance tools.
Customer demands have also evolved substantially; competition, productivity and
quality requirements compel them to adopt a process-based approach.
b Customer value creation process
The customer value creation process is based on the main flow (C Fig. 1),
i.e. core business, such as product manufacturing, transport of persons or
conveyance of a load.
This process requires equipment in the form of machines and automated
devices. This equipment can be confined to a single place, such as a
factory, or else spread over extensive areas, as is the case for a water
treatment and distribution plant.
To work smoothly, the process requires additional flows such as electricity,
air, water, gas and packaging.
The process engenders waste which must be collected, transported,
treated and discarded.

The automation equipment
Automation equipment features five basic functions linked by power and
control systems (C Fig. 2).
b Five basic functions
v Electrical power supply
Ensures the distribution of power to the power devicescapacity and
control parts.
It must be uninterrupted and protected in compliance with electrical
installation and machines standards. This function is usually ensured by a
circuit-breaker or fuse holder switch.
v Power control
Controls loads driven by the automatic device, either a contactor is used
as a direct on line starter or an e
