I 400
The graphic terminal
General presentation
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.
RACK
version
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.
STAINLESS STEEL CASING
version
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.
The I 400 Graphique Terminal is available in a STAINLESS STEEL casing or a RACK version.

General principle
Due 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.
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.
Client Field Bus
This design enables three basic configurations described
below.
Coupler
CAN Field Bus
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.

The transmitter
The main functions of the I 400 transmitter are to :
& make a direct connection of 1 to 4 load cells (or 6* load cells through an
external connection box),
& convert the analog measurement signal to a digital signal,
& communicate the information through the field bus.
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.

Optionally, it may be equipped with an interface card that contains six digital
inputs, six digital outputs and one analog output. All these outputs may be
controlled by any equipment in the CAN network (graphic terminal or CLIENT
logic controller).
The I 400 transmitter is available in two versions : a black zinc plated steel
version and a stainless steel version for the most difficult environments.
Stainless Steel
version
* or 8 high impedance load cells.
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.
Client Field Bus
The coupler
The main function of the I 400 coupler is to form the interface
between the CAN field bus used by the weighing system and
the main field bus, if the main field bus is not a CAN bus.
Optionally, it may be provided with one or two accessories that
can manage communication or delocalized inputs/outputs close
to the coupler.
The I 400 coupler can interface the CAN bus with several types
of field buses including :
& Profibus
& DeviceNET
& TCP/MODBUS Ethernet
