Load indicators and transmitters I 400 - PRECIA MOLEN - #1

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 :

4 up to two communication type accessories (RS 232, RS 422/485, serial USB or USB key),

4 up to four input/output type accessories (2 inputs / 4 digital outputs) or 4-20 mA analog outputs),

4 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 transferfunction, 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.

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.

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 :

4 the Graphic Terminal,

4 the associated weight transmitter(s),

4 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.

The I 400 Graphique Terminal is available in a STAINLESS STEEL casing or a RACK version.

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 main functions of the I 400 transmitter are to :

4 make a direct connection of 1 to 4 load cells (or 6* load cells through an external connection box),

4 convert the analog measurement signal to a digital signal,

4 communicate the information through the field bus.

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.

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.

The I 400 system is used in many application fields :

Silo weighing Dosing by batch

Packaging (in drums, bags, etc ...) Filling or unloading flow regulation Check weigher

Optionally, it may be provided with one or two accessories that can manage communication ordelocalized inputs/outputs close to 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.

The I 400 coupler can interface the CAN bus with several types of field buses including :

4 Profibus

4 Devi ce NET

1 TCP/MODBUS Ethernet
