The group of converters used for an application become a single peripheral unit of the PLC/PC using
standard FIELD BUS (Profibus or DeviceNet), and the architecture of the plant control system
becomes of the type shown in the figure.
With the Bridge philosophy, the user or the manufacturer can write motion programs using a standard
PLC, thus avoiding to realise specific application communication protocols.
This philosophy aims at allowing the manufacturer to reach his goals, in terms of time-to-market,
allowing him to focus the efforts on the design activity and avoiding multiple problems connected to
the drive use and interfacing.
