General principleDue to its design, the I 400 system provides an upgradeable solution to the different problems that can arise with integration of weighing into the industrial process. They consist of three main elements structured around a CAN Open field bus. These elements are :& the Graphic Terminal,& the associated weight transmitter(s),& the field bus coupler.
This design enables three basic configurations described below.
In a first configuration, the Graphice Terminal assures complete management of the weighing system and controls the different associated automations through a standard application or an application specifically developed for the need. This configuration forms a complete and independent weighing system.
In a second configuration, the addition of a field bus coupler enables the client application to manage all or some of the process without performing functions specific to weighing and possibly some directly related automation operations. This configuration forms an independent weighing system with central data management.
If the client system manages the entire application and management of the measurement, it can replace the Graphic Terminal. This third configuration only consists of a set of transmitters directly controlled by the client application.
For the most simple applications, the transmitter can be integrated into the Terminal thus being converted into a weighing indicator while maintaining its functional performances.

The two main functions of the I 400 graphic terminal are to control the weighing application (in other words management, checking and control of the different transmitters connected to it) and to communicate through the field bus.
Optionally, it may be equipped with various accessories that are functionally complementary to its main functions :& up to two communication type accessories (RS 232,
RS 422/485, serial USB or USB key),& up to four input/output type accessories (2 inputs / 4
digital outputs) or 4-20 mA analog outputs),& A Data Storage Devis (DSD) accessory for keeping the
history of weighing for Trade Use.
The USB key interface, apart from performing a conventional data transfer function, also facilitates updating the application and transferring man-machine dialogue texts thus facilitating adaptation to different trades, languages, etc.
Occasionally, it may be provided with a measurement interface card thus enabling local management of a load receptor equipped with 1 to 6 load cells (or 8 high impedance sensors). In this case, it may become a simple weighing indicator with features varying from the most simple to the most complex.
