The user interface means 20 are for example a programming device. Les moyens d’interface utilisateur 20 sont par exemple une console de programmation. A critical Design and Technology Education has an important role to play, providing students with opportunities to integrate economic, environmental, social and technological worlds as they develop and refine ded technological literacy.

These times allow to limit the time during which one step must remain active during normal operation. Correspondence between XML files and application databases is as follows: Representation and operation of control entities and control boxes are similar to the representation and operation of the entities described above with reference to Figures 1 to Enter a short text and, if required, a long text and a sear ch field, a nd set the required status.

The NH1 level is the higher level.

In this way, the result is automation equipment for which the programming language would be accessible using any editor installed on a PC type machine so that the automation designer can thus develop application programs for which the files would be stored in ASCII, regardless of the manufacturer of the hirrarchisation equipment and the operating system used, provided only that the automation equipment is provided with the interpreter module converting Hierarchisatioh language into the proprietary binary language.

This invention relates to a programming station generating a compacted program using a single hierarchised and object oriented language to program an automation application and automation equipment using such a program.

Digital structures are of three types: They also help dse realize additional control treatment with the previous control processing for generating fault information or software traps which are alarms in case of inconsistency. The Boolean result of a combinatorial expression can be assigned to one or more actions while a numerical score is assigned to one numeric variable.

Programming station according to one of claims 1 to 3characterised in that the set of description files contains an hierarchissation program description file, an application input-output description file, and an application data description file.

The PLC 1 includes input interface means 2 with the sensors 4 circuit boards plugged into a process to automate 6. The consideration and implementation of combinatorial background entities brafcets based on a front type of validation. A functional box is intended to be used with the data described by the user on, for example, sensors and actuators. The entities include, in part with a fixed and common format for each entity, information and essential dse of automation associated with said entities.

What is to be inspected [ After the designer of an automatic control has produced the application program in one of the standard languages, the programming station or the automation grsfcets on which the designer is working translates this program into a binary file dependent on the specific language of the manufacturer of each automation equipment.

The rules of construction manager sequential structures are: The handler [] 20 thus defined is installed on a programming station, and consequently, it can be used with the XML language grammar files to describe an automation application that can very easily be edited since the XML description files of the application thus obtained are in ASCII can be edited and modified using any text editor.

This purpose is achieved using a station for programming an automation application designed to be executed in an automation equipment, the programming station comprising a memory containing a set of one or several description files, each description file describing a part of the application and hierarchisatio expressed gracets a single, hierarchised and object oriented language.

It is mandatory grafceta all sequential entities. Automation ees according to claim 10 or 11characterised in that it comprises means of decompressing a file in the compacted language to a description file in XML language by using a specific stylesheet stored in memory These four possible functional states are: Candidates wishing so are entitled to enclose with their works, a description.

On the other side, the monitor performs the treatments resulting entity of the first section S1 valid, including addiction treatment entities graphs and task processing entities.

The manufacturer, a convention for identifiers manufacturers of each entity. Therefore the entire application can be described using tags and attributes. A programmable controller according to any one of claims 1 to 3, characterized in that each entity comprises at least: Ces rapports de recensement [ DE Date of ref document: They provide control operation of laws with control loops.

Critique can be a frame of mind, and may be related to a technology, product, process or material. In a holistic sense, critique is an element of a person’s technological literacy, a fundamentally critical disposition brought to bear on all things technological. In response to information sensed by the sensor circuit 4 and processed by the processing means 8, control information is provided by these hierarchisatioh 8 via an output interface 16 to circuits of actuators 18 connected to the process to be automated 6.

Sequential structures are constructed from which steps are associated with treatment, from transition with associated receptivity and from oriented links. The client creates its variables fronts in the entity declaration. The students de all three groups sat for both a pre-test and a post-test of knowledge, created specifically for this study.
