Today automated application not only needs to intellectualize product, but also needs to be able mutually to correspond the realization network function, but the main line is the means of communication without doubt which the current very many automatic equipment chooses. When enters any to make the processing factory, the process enterprise or the energy enterprise, you are not difficult to discover hundred and thousand of executions and the sensor all carry on the correspondence through a main line with theirs controller.

Many main lines standards cause the industry correspondence complication
Among many main lines standards, the national recommendation standard also played the vital role, if (FF) the HI standard occupied the dominant status in the American DeviceNet main line and the foundation field bus. Among them, DeviceNet widely applies to the automobile, the material transporting and the manufacture processing industry, but FF gives full play in the process control domain. Similarly, the Profibus standard also is these domains powerful competitors, it occupied the absolute share in the European market. In addition, the Profibus standard also extremely is widespread in some specific profession applications, likes Profibus DP in the automobile machine shop application is so. However, some very interesting phenomenon is, Germany's CANbus main line itself also uses in the automobile profession. But, how no matter looked, the entire market basically may divide into the process industry and the manufacture industry two kinds.
Along with the industrial enterprise for the realization quickly, the highly effective production and the movement but the unceasing investment, hangs on these different main lines the intellectualized installment rapidly is increasing. The main line application indeed can give the terminal user enterprise to bring the vitality and the formidable handling of traffic ability, but simultaneously also gives the intellectualization to install the supplier to bring a difficult problem: They must act according to the multitudinous main line separately to design the different main line product, satisfies each kind of main line the need. In addition, control wiring in the field bus is an item of very time-consuming between work, moreover in the installation work not too to be easy to succeed. Such work complex obviously operates a simpler tendency with today equipment is runs counter to. System integration business hoped for has one kind can namely insert namely with (plug & produce) solution, does not need laboriously to consult the thick product parameter instruction booklet again which the supplier provides. This actually is one kind to the industry correspondence flexibility, the simplification demand.

Simplifies the entire field bus
Was precisely based on such starting point, ABB Corporation proposed one kind was called "the field bus plug (FieldBus Plug, FBP)" the concept, namely the design produced one kind to be allowed the simple momentary connection any main line system product to simplify the entire field bus.

ABB Corporation has been able to provide has now to have the main line irrelevant connection the plug-in unit, this meant the supplier no longer will need from now on according to the different goal main line market redesign product. Each kind of automatic equipment all may connect on the main line through the corresponding main line plug-in unit, but one kind of main line agreement correspondence has one kind of main line plug-in unit. For example, must connect a Taiwan Telegraphic Transmission machine starter on the DeviceNet main line, only needs the DeviceNet main line plug-in unit and the general standard electrical machinery starter connection then.
This kind of field bus plug-in unit can meet all electrons data transmission needs, it will connect on the main line data conversion standard automatic equipment will be able to distinguish neutrality data format.
ABB now also can provide the control product, if the standard FBP electrical machinery controller and the electrical machinery starter, these products all have a main line irrelevant connection. All installation engineer only to need the corresponding corresponding main line connection FBP ties cable which will prepare directly to hang to the field bus above.
The FBP field bus plug may complete some special switches and the automatic equipment and the process controller connection. The plug-in unit design extremely is also simple, an end is has the versatile archery target the connection which has nothing to do with with the main line type, another end conforms to the concrete some kind of main line standard connection. Inside the compact connection has intellectualized the electron conversion system, may the neutral equipment data conversion be the language form which main line and so on AS-i or DeviceNet can understand.
Because the FBP concept certainly not again composes one kind of main line to come, but is the many kinds of field bus which has all uses, is an open system, therefore FBP can suit any PLC system. Will connect the field bus and power supply main line time in the automatic equipment, will use the coupling all will be already prepares, might insert standard product, thus also will not need to awaken the line cable to cut, the isolation and the preparatory work.
