Description
Technical field
This utility model relates to a kind of experiment porch, particularly relates to a kind of PLC experimental box supporting multiclass fieldbus.
Background technology
General numeric class experimental machine is all PLC circuit board and electrical equipment is directly exposed to outside, it is easy to enter dust,
Non-watertight, experimenter the most easily touches the loop of electricity, and safety is the highest.It addition, within considerable time, multiple existing
Field bus standard to deposit be the principal character of Evolution of Fieldbus, and existing PLC numeric class experimental machine can be supported on-the-spot total
The limitednumber of line, limits range of application.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of PLC experimental box supporting multiclass fieldbus, to solve
Deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of PLC experimental box supporting multiclass fieldbus is provided, wherein, including workbench, and is located at described work
Bus protocol switched system in platform, described workbench is provided with modular PLC, display touch screen, power-supply controller of electric,
Described bus protocol switched system connects described modular PLC and provides external signal interface, and described bus protocol is cut
Being provided with protocol conversion bridge or MPR in changing system, described external signal interface includes serial ports, Profibus bus
Interface, Interbus EBI, Modbus EBI, Devicenet EBI, Controlnet EBI and
LONworks EBI.
The PLC experimental box of above-mentioned support multiclass fieldbus, wherein, described bus protocol switched system also provide for industry with
Too network interface.
Compared with the prior art, the beneficial effects of the utility model are:
PLC is located at inside control chamber, signal terminal in need be all individually lead-in wire on the panel of electronic box, panel
Terminal uses contact pin type, and metal part is covered by insulation sleeve, provides the connectivity port of serial ports, network interface and bus simultaneously, permissible
Support the Field bus type of more than three kinds, the study personnel of many applications can be allowed to carry out lab exercise easily.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and this practicality is new
The schematic description and description of type is used for explaining this utility model, is not intended that improper restriction of the present utility model.?
In accompanying drawing:
Fig. 1 is the structural representation that this utility model supports the PLC experimental box of multiclass fieldbus；
Fig. 2 is the bus protocol switched system internal logic that this utility model supports the PLC experimental box of multiclass fieldbus
Schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can
To be mutually combined.
With reference to shown in Fig. 1, Fig. 2, this utility model supports that the PLC experimental box of multiclass fieldbus includes workbench 1, and
The bus protocol switched system 2 being located in workbench 1, workbench 1 is provided with modular PLC 3, display touch screen 4, electricity
Source controller, bus protocol switched system 2 link block formula PLC 3 also provides external signal interface, and bus protocol switches
Being provided with protocol conversion bridge or MPR 20 in system 2, external signal interface includes that serial ports 21, Profibus bus connect
Mouth 22, Interbus EBI 23, Modbus EBI 24, Devicenet EBI 25, Controlnet bus connect
Mouth 26 and LONworks EBIs 27.
It addition, bus protocol switched system may be provided for EPA mouth 28.
From above-described embodiment it can be seen that advantage of the present utility model is:
PLC is located at inside control chamber, signal terminal in need be all individually lead-in wire on the panel of electronic box, panel
Terminal uses contact pin type, and metal part is covered by insulation sleeve, provides the connectivity port of serial ports, network interface and bus simultaneously, permissible
Support the Field bus type of more than three kinds, the study personnel of many applications can be allowed to carry out lab exercise easily.
Above specific embodiment of the utility model is described in detail, but this utility model has been not restricted to above
The specific embodiment described, it is intended only as example.To those skilled in the art, any equivalent modifications and replacement are the most all
Among category of the present utility model.Therefore, done under without departing from spirit and scope of the present utility model impartial conversion
And amendment, all should contain in the range of this utility model.
