Drinking water supply

This example illustrates part of an infrastructure for water treatment and distribution. It consists of a set of units spread over a territorial area.

This kind of application must be standalone and ensure a continuous supply. Customers give great attention to supervision and maintenance of the installation.

The features of the station are:

-          4 pumps of 7.5 kW with AC drives,

-          a dozen of sensors (pressure, output, etc.),

-          an automated device to control pump sequencing and communication,

-         remote supervision of the installation.

The choice will focus on a distributed implementation. The table below shows the best one.

The most suitable implementation is the Ethernet one, ensuring total transparency in the installation. The ASI bus is limited by its low data exchange capacity. The CANopen ones can be used with a modem but their possibilities are still restricted
