Technical field
The present invention relates to the automatic control system structure.More particularly, the present invention relates to how access control system data of factory and enterprise application software, these control system data comprise factory and business administration, operation, configuration, maintenance and the needed fieldbus data of control system diagnostic function.
Background technology
Automatic control system such as process control, discrete control, control in batches (having made up process and discrete control), machine tools control, running control and Robotics, all is vital to all industrial sectors.One of the strongest demand is exploitation and uses open to the outside world and the system of " can co-operate " in modern control system.The opertaing device of opening, interoperable system allows different manufacturers to make is communicated by letter in same system and is not needed customization to programme with cooperation.
Driven by factory and business administration, Application Software Provider, opertaing device manufacturer and terminal user to propelling that open, interoperable control system.Open, interoperable control system are wanted in factory and business administration, provide because they need visit all control system information to optimize factory and the required analysis of enterprise's operation.That the client application software vendor is wanted is open, interoperable control system be so that their software can utilize operation standard operation system and the criterion calculation machine platform by the communications systems standard interconnection to go the access control system data.The opertaing device manufacturer wants open, interoperable control system, because this kind system allows them that their production marketing is given more terminal user and reduced cost of development simultaneously.The terminal user wants open, interoperable control system, and only best application software and opertaing device are selected by the system for them so that they can not consider the manufacturer.
In order to make control system become real opening and interoperable, the communication system in equipment, equipment between the client layer of (on the communication system layer) and computing machine/application software integrated morphology must be prescribed and be made into open." fieldbus " is the generic term that is used to describe the automatic control system of these types.
One of real opening and interoperable field bus control system are by fieldbus foundation (Austin, the FOUNDATION that TX) provides
TMFieldbus (" FF ") system.The fieldbus (H1) of FF client layer and low speed 31.25 kilobits/second is described in the patent of ' 892 above-mentioned.Fast Ethernet (HSE) fieldbus that operates on 100 mbit/or the more speed is described in the application of ' 697 above-mentioned.' 892 patent and ' 697 application are transferred to the application's assignee.
H1 is for other control ability of field level and integratedly provide open and interoperable solution, and HSE provides opening and interoperable solution for distributed control on the high performance communication system very much being commonly called one of Fieldbus Control " backbone " net.HSE controls key the gathering from the information in for example this class low speed opertaing device of H1 equipment and other opertaing device, and this information is used in supervision and the Advanced Control application.HSE control is key to be assembled from the data in for example this class High-speed Control equipment of HSE equipment and other subsystem, and goes to provide the visit/change of H1 and HSE control information by the control system computing machine.
Factory/enterprise application software operates in " client computer " and " server " level in the control system hierarchy.Need an opening and interoperable integrated fieldbus data server architecture (being meant client-server), it will be provided for the framework of fieldbus data " semanteme " (how application software understands this control system data) and common standard, and no matter this fieldbus data is H1 or HSE data or other control data.Before the present invention, the have to artificial customization and adjust the data of receiving from each server to the visit of fieldbus or other opertaing device data is provided of client application software on factory/enterprise computer is because each server is differently discerned same semantic information and represented.Requirement for modern server is the needs of eliminating artificial customization or adjustment client application software; The application is promptly at this requirement.
(runtime) data subset was adaptive automatically when existing server standard provided very limited operation, because this is according to only understanding by the grammer of for example message structure and so on.For example, (Boca Raton, it is limited adaptive that the standardization of OPC standard FL) by the grammer of basic access mechanism and runtime data (for example simple process variable (PV) and adjustment point (SP)) provides from OPC (OLE that is used for process control) foundation.The extraneous information that the OPC standard is enough to allow to be called " attribute " usually defines " class " attribute of runtime data.Generic attribute comprises (DD) information of runtime data " device description ", for example helps word string, engineering unit and parameter tags.Some DD information is very complicated, for example comprises condition, menu and method (they are c programs).Other generic attribute (CF) is provided by " the ability file " of the limit of power of describing field bus device or other opertaing device, for example: the initial value of maximum number of parameters, parameter and maximum communication session number.,, do not have standardized definition for generic attribute though OPC allows server definition generic attribute, thus limited with the interoperability of client application software and by client application software carry out adaptive automatically.
In addition, promptly allow to server data carries out standardization to generic attribute, which " example " that client application software also needs to know runtime data is described by generic attribute.That is to say that the generic performance tells that the runtime data of what type of client application software is just accessed; But they can't discern just accessed concrete data.Example information can be provided by the application directory (data during its positioning trip) in the visit field bus device, but be similar to generic attribute, here the not standardization of application directory information definition, thus make client application software interoperability and adaptive automatically be impossible.
Senior people/machine interface (" HMI "), trend, asset management, configuration, maintenance, diagnosis and factory/business administration application software must be able to be visited runtime data and generic attribute and application directory semantic information, and this allows this software automatically to discern, translate and handles runtime data and needn't manually get involved.At last, for effectively, client application software must be visited runtime data and semantic information by individual interface.
The OPC standard can not be automatically and is supported these senior application effectively, because the same-interface that does not have open and interoperable framework or standard to be used for visiting by current usefulness runtime data provides above-mentioned semantic information to use to client software.
Needed is a kind of framework and the common specification that is used for integrated fieldbus data server architecture, and it can provide the semanteme of simple and complicated runtime data to client application software.
Needed is a kind of framework and the common specification that is used for integrated fieldbus data server architecture, its migration is to existing factory/corporate client machine application software, the for example support of HMI and other OPC software application, the needed semanteme of automatic identification, translation and processing to the runtime data of higher order client application software (for example factory/business administration, configuration, maintenance and diagnostic application software) carries out standardization and integrated simultaneously.
Needed is a kind of integrated fieldbus data server architecture, and it replenishes H1, HSE and other fieldbus structure, so that factory/enterprise application software can utilize corresponding semantic information automatically to translate this runtime data.
Needed is a kind of integrated fieldbus data server architecture, and it is provided for the individual interface of factory/enterprise application software visit runtime data and corresponding semantic information.
Summary of the invention
Embodiments of the invention have overcome above-mentioned and other shortcoming.Embodiments of the invention satisfy above-mentioned needs.Embodiments of the invention provide a kind of new and control system structure improvement, it has the individual server interface that is used for client application software, and it eliminates manual intervention by online senior factory/business administration, operation, configuration, maintenance and the diagnostic application software of providing to the instant electronic access of runtime data and semantic information.
Embodiments of the invention are called " integrated fieldbus data server architecture " (IFDSA) jointly at this.IFDSA provides the framework and the standard of the semantic information that is respectively applied for the runtime data of describing in mapping ' 892 patent and ' 697 application (such as H1 and HSE field bus device data), and is client application software definition individual interface.The IFDSA framework enabled is adaptive automatically to FF and other opertaing device type.
The elimination of the manual intervention of the foundation by providing a kind of method and apparatus to realize to be used for senior application bag, described method and apparatus is used for: during the operation of visit work FF equipment " effort scale ", one of construction/renewal is formatted as and browses tree structure from the standardization of the obtainable OPC standard of OPC foundation compatibility, and FF directory information (it is provided for semantic information and other opertaing device runtime data of all FF fieldbus) is mapped to new server directory.Server directory comprises the semantic information identical with the FF catalogue, but is formatted as and the OPC standard compatibility that can obtain from the OPC foundation.The browse tree of OPC compatibility and semantic information are followed serviced device and are offered client application software pellucidly.
IFSDA has realized individual interface, because the client application software of client no longer must use interface separately to visit semantic information and runtime data.Because FF semanteme and runtime data are on communication layers to the mapping of OPC standard, so this solution is still remained valid when embodiment develops into the technology of for example renewal of web service and so on.

The II.IFDSA assembly
Fig. 2 has illustrated that one of IFDSA50 can be imitated embodiment.As shown, IFDSA50 preferably includes OPC160 and field bus device 280 (for example, H1 equipment 170 and HSE equipment 120-are referring to Fig. 1).The function of OPC160 and assembly can be integrated in the single OPC160 computing machine or be extended in a plurality of OPC160 computing machines.OPC160 is preferably via fieldbus networks 290 communicate by letter with field bus device 280 (for example, H1 network 150 and Ethernet 140-are referring to Fig. 1).
In the illustrated embodiment, OPC160 preferably includes client application software 180 and OPC client computer 210.The information that client application software 180 uses OPC client computer 210 to visit in the opc server 220.OPC client computer 210 and opc server 220 can be arranged in single computing machine, perhaps, they may the computing machine that separates on communication network in (communication network between the client-server is not shown in Figure 2).
Operate in client application software 180 among the OPC160 and can comprise the various softwares module of separating of program of separating or same software (for example, as).For example, client application software 180 can comprise people/machine Application of Interface software 181, maintenance/diagnostic application software 182, configuring application software 183 and other factory/enterprise application software 184.Preferred embodiment has defined the existing client application software that will be included in other factory/enterprise application software 184.
Refer again to embodiment as shown in Figure 2, the 2nd OPC160 computing machine preferably includes opc server 220 and FF server module 230.0PC server 220 for example can be a virtual server, and preferably includes a server function of browse 270.Preferably, between opc server 220 (the server function of browse 270 of more clearly saying so) and OPC client computer 210, enable and keep communication.FF server module 230 preferably includes FF catalogue 240, mapping function 250 and server directory 260.Preferably also between opc server 220 (the server function of browse 270 of more clearly saying so) and FF server module 230 (server directory of more clearly saying so), enable and keep communication.
The mapping of III.IFDSA catalogue
Continue with reference to embodiment illustrated in fig. 2, FF server module 230 is surveillance operation tabulation 400 preferably, and it represents the field bus device of the work in the field bus device 280.In a preferred embodiment, come activity of constructing tabulation 400 according among the annex I and FF standard that can from fieldbus foundation, obtain.The field bus device 280 that effort scale 400 identification FF server modules 230 can be used.For each equipment of listing in the effort scale 400, the respective list of the specific identifier of manufacturer is arranged, be called object dictionary (OD) index (the OD index is not shown in Fig. 2).Object when the OD index has corresponding operation at the scene in the bus apparatus 280.Object exists and is described in the application of ' 892 and comprises during the operation imitated in the equipment: Resource Block object, converter block object, functional block object, trend object, view object, linked object, alarm object, system time object, functional block scheduler object and Network object.
Object when though manufacturer can define other operation, preferably by the FF standard quoted among the annex I during with operation object definition be the FF object.In arbitrary situation, above mentioned and DD that in ' 892 application (and FF standard of listing among the annex I), describe and CF technology object when preferably being used to describe operation.DD and CF file extent the description of each object in the equipment, control system needs this to describe the connotation of translating in the field bus device that comprises human interface function's (such as calibration and diagnosis) of data.
The DD/CF file can write out according to ASCII text or any standardization programing language (such as C, C++ or SmallTalk).In a preferred embodiment, the DD file is write according to DD language (DDL), and the CF file is the described ASCII text file of FF standard as listing among the annex I and can obtain from fieldbus foundation.
The OD index is used as a determinant attribute in the FF protocol service and visits when operation object.Therefore, client application software 180 can visit this runtime data in the field bus device 280 by the corresponding OD index that obtains runtime data from FF catalogue 240.
Object modeling was " an OPC item " when OPC160 will move.The OPC item is discerned by " ID " that comprise the specific title of manufacturer.OPC item in the opc server 220 is via server function of browse 270 gives OPC client computer 210.Server function of browse 270 allows opc server 220 location OPC item in according to the tree structure of OPC standard structure.OPC client computer 210 uses server function of browse 270 to locate the item of being concerned about.
Current, do not have standardization branch and leaf node tissue or be used in ID name in the server function of browse 270, therefore, under the situation of the human translation that does not have browse tree and each OPC item wherein, OPC client computer 210 can not be located the OPC item of being concerned about.This stops the OPC item in 210 automatic visits of OPC client computer and the processing opc server 220.
In order to address this problem, IFDSA50 provides a standard server catalogue 260, creates it and represents FF catalogue 240.Server directory comprises the object semantic information identical with FF catalogue 240, but it mappedly comes and OPC object compatibility mutually.The name of tree structure 261 definition branches and leaf node tissue and field bus device 160 is browsed in standardization in the server directory 260 so that server function of browse 270 can by the semantic information of the OPC compatibility in the server directory 260 locate it, the expression of field bus device 280 and their data.In case be positioned, then the semantic information of OPC compatibility is pellucidly offered client application software 180 via server function of browse 270 with relevant OPC160 service with data value (if any).
Fig. 3 A has illustrated that creating server directory 260 enables the embodiment of the method 300 of visit automatically.Just as can be seen, when integrated control system method 300 beginnings 310 time of powering, and it comprises the steps: to visit the effort scale 400 of field bus device 280, step 320; Standardized tree structure 261, the step 330 browsed of construction/renewal; From work field bus device 280 in the AP catalogue and the FF object tools in FF catalogue 240, step 340; FF catalogue 240 is mapped in the server directory 260 step 350; Whether judge has an effort scale 400 to change step 360 here; And, if, repeating step 330-360 then; And if not, then repeating step 360.
Preferably use in the FF of annex I standard definition and can carry out accessing step 320 from the protocol service that fieldbus foundation obtains.Construction/step of updating 330 uses effort scale 400 equipment identification informations that read from field bus device 280 to construct the standardized tree structure 261 of browsing at first.
The protocol service of preferably using in the FF of annex I standard definition and can obtaining from fieldbus foundation is come the reading of information in the execution in step 330.(, see also the corresponding description of Fig. 3 B and following Fig. 3 B for the more detailed description of step visit data thus.) preferably carry out copy step 340:1 like this) and use in the FF of annex I standard definition and the protocol service that can from fieldbus foundation, obtain read with effort scale 400 in the AP catalogue and the FF object of the corresponding field bus device 280 of working equipment, and these data are placed in the impact damper and 2) data are copied to FF catalogue 240 from impact damper.Mapping step 350 by for each equipment an AP catalogue and be included in the OPC item of each FF object map in the server directory 260 in the FF catalogue 240, come the data map in the FF catalogue 240 is arrived server directory 260.Being described in more detail and, seeing also the respective description of Fig. 4-6 and following they for this step these replacement step that is mapped to the OPC item.
Continue with reference to figure 3A, determination step 360 dynamically judges in the effort scale 400 whether change.Step 360 uses the agreement identical with step 320 to visit effort scale 400, then the new copy of this effort scale that has just obtained and previous copy is compared and has judged which field bus device has added in the field bus device 280 or therefrom deleted since the execution of the last time of step 360.Therefore, determination step 360 makes IFDSA50 dynamically be mapped to server directory 260 to FF catalogue 240.
Fig. 3 B has illustrated to have and can imitate standardization to browse of tree structure 261 can to imitate server directory 260, and illustrated the embodiment of construction/step of updating 330.As shown, field apparatus for each work in the field bus device 280, this standardization is browsed tree structure 261 and is comprised an effort scale catalogue 262 inlets and facility inventory 263 inlets, the field apparatus of this each work is quoted clearly by an effort scale catalogue 262 inlets, as shown in FIG., perhaps impliedly be cited as the child node or the attribute (not shown) of effort scale catalogue 262 inlets.
Referring to Fig. 2 and 3B, preferably, the tissue of server directory 260 structures and FF catalogue 240 structures is complementary.Each AP catalogue in the FF catalogue 240 is quoted by a beginning OD index and a plurality of object and is formed.In a preferred embodiment, this equipment identification information (for example, device id, fieldbus networks address, physical equipment mark and other related data) provides the semantic information that allows client computer to discern field bus device 280 automatically.It preferably is read from the field bus device 280 of the protocol service using among annex I and can obtain from fieldbus foundation, define in the FF standard, and preferably, utilize the item ID/ path that produces automatically, be mapped in the server directory 260 according to one of following two modes:
1. each the AP catalogue when being mapped to server directory 260, in the FF catalogue 240 is quoted a beginning OPC item that comprises the branch of this object by identification and is quoted and form, and the subobject of this object is represented as the item under this branch.Browsing order every under this branch keeps this OD index according to the defined order of representing in to the AP catalogue in the FF standard of object; Perhaps
