As a concrete example, as shown in Figure 1, suppose that the semiconductor equipment comprises technique unit 1, technique unit 2, EFEM and wafer transfer system, then the next unit comprises a plurality of slave computers, each slave computer links to each other with technique unit or EFEM and wafer transfer system in the semiconductor equipment respectively in a plurality of slave computers, in Fig. 1, show the situation that the next unit comprises three slave computers, three slave computers are Programmable Logic Controller PLC1, Programmable Logic Controller PLC2 and Programmable Logic Controller PLC3, wherein, PLC1 links to each other with technique unit 1, PLC2 links to each other with technique unit 2, and PLC3 links to each other with the wafer transfer system with EFEM respectively.In Fig. 1, show the connected mode that communicates by Ethernet between a kind of host computer IPC and the next unit.
As from the foregoing, the supervisory system based on the semiconductor of OPC standard equipment of the embodiment of the invention adopts " IPC(industrial computer, i.e. host computer)+PLC(programmable logic controller (PLC)) " two-stage control model.Each PLC of bottom is responsible for controlling unit module (established technology unit, EFEM and wafer transfer system) separately, and host computer IPC is responsible for the state and the execution of managing each PLC of each unit module of monitoring in real time.Each PLC realizes and host computer IPC and physical connection each other thereof by Industrial Ethernet.Thereby between the assurance levels, in the normal communication, can realize the target to semiconductor equipment decentralised control and centralized operation.
Be in charge of the operation that whole semiconductor is equipped based on the supervisory system that the semiconductor of OPC standard is equipped, major function comprises the condition monitoring of each unit module of semiconductor equipment and the maintenance of local data, namely read and show state variable and the technological parameter of each unit module in real time, download technical recipe, and send every steering order etc., can realize the unified scheduling of each unit module, thereby guarantee the safety in production of whole technological process.
The upper strata monitor system software operates among the host computer IPC.In order to guarantee the reliability of data access, the present invention adopts the OPC technology to realize that the upper strata supervisory system is to the visit of each sub-control system (being each PLC).The signal of OPC architecture as shown in Figure 2.
Particularly, upper strata supervisory system (host computer IPC) comprises opc server and client.Opc server disposes the next unit information (being title and the address of each slave computer) with the communication of realization opc server and the next unit, and the next unit is monitored and managed; Client links to each other with opc server, comprises OPC Data access module and user interface, realizes reading, handle and showing of data, and the functions such as transmission of operations instruction.The PLC of lower floor sets up a plurality of memory blocks (DB) specially and is responsible for depositing all data (comprising state variable and technological parameter etc.) temporarily, client can be read and write the data of DB among the PLC of lower floor in real time by the visit opc server, thereby realizes the information interaction of technologist and semiconductor equipment.The user interface of client is in order to realize mutual between technologist and the semiconductor equipment.Further, user interface includes but not limited to: edit sub-interface, dispose sub-interface, safeguard sub-interface, monitor sub-interface and help sub-interface.
When client and opc server carry out communication, client can be by creating target opc server and the support of visit opc server the mode of interface realize and opc server between information interaction, that is: client is used for creating target opc server, and being connected between foundation and the target opc server, and create and interpolation OPC group objects and OPC item object, and according to OPC group and OPC item, client is obtained data from opc server.
Further, after closing described client user interface, client also is used for removing OPC item object and OPC group objects, and being connected between disconnection and the target opc server, and eliminates target opc server to discharge resource.
Particularly, OPC is made up of two sockets: OPC self defined interface (OPC COM Custom Interfaces) and OPC automation interface (OPC OLE Automation Interfaces).Self defined interface efficient height, by this interface, the client can bring into play the optimum performance of opc server, is fit to adopt the client of C Plus Plus; Automation interface has been simplified the realization of client applications, be fit to adopt the client of VB language, but need carry out type checking during operation, influences the travelling speed of program.Therefore, the present invention adopts the OPC self defined interface to realize that client is to the visit of opc server.
From bottom, the raw data that the OPC technology obtains physical equipment sends to Process Control System (as PLC and opc server), again the data of Process Control System is delivered to application program (in client); From high level, opc server is made up of three objects: target opc server, OPC group objects and OPC item object.
(1) target opc server
Target opc server is the main object of opc server program.In the OPC of client Data access module, at first need to create this object, finish required function by its interface again.It below is the several main opc server interface that needs realization.
1) the IUnknown interface is the basic standard interface that all com components all must be realized, it carries out the interface inquiry for CLIENT PROGRAM provides the QueryInterface method.
2) the IOPCCommon interface is the interface that all kinds of opc servers all use, and can be certain specific client/server dialogue by this interface and arranges and the local sign of inquiry (LocalID).Like this, the operation of a CLIENT PROGRAM will can not influence other CLIENT PROGRAM.
3) the IOPCServer interface is the main interface of target opc server.CLIENT PROGRAM can be created, inquire about by this interface and the deletion group objects, and understands the information of opc server self.These information comprise the number of server creation-time, running status, group objects and version number etc.
4) the IOPCItemProperties interface provides a kind of method of conveniently browsing data item attribute in the opc server memory block for CLIENT PROGRAM.These attributes comprise quantities, setting value, high limit alarming value, lowest limit alarming value and note etc.By this interface, OPC client need not to create and the management group just can directly obtain these information, has simplified operation.
(2) OPC group objects
After target opc server is created the OPC group objects, the pointer of OPC group objects is passed to client, by client direct control group objects.The data item (mainly comprising each technological parameter, state variable and command variable) that client will need to visit is added in same group as the OPC item.Be that unit carries out to organize when client is carried out data access to opc server, namely CLIENT PROGRAM is carried out unified read-write operation to the OPC item in organizing, and has improved the efficient of data communication.
Client is managed the state of whole group objects by the IOPCGroupStateMgt interface.And the IOPCItemMgt interface allows the CLIENT PROGRAM group objects to add, delete and manage the OPC item of its containing.
(3) OPC item object
Wherein, the OPC item represent with opc server in being connected of data.It is pointed out that the OPC item is not actual data source, just expression and data source is connected.Therefore, when adding the OPC item in OPC group, each address of strict difinition guarantees the correctness of data read.
In the supervisory system of upper strata, client and opc server reciprocal process mainly be divided into following step, as shown in Figure 3, comprising:
(1) defines and creates an OPCSever object (target opc server).
(2) set up and being connected of OPCSever object.Be initialization COM storehouse, utilize the CLSIDFromProgID function to obtain CLSID.Based on the CLSID that obtains, client is created an OPC Server object, and obtains a pointer variable IOPCServer who points to server object.
(3) definition and interpolation OPCGroup object (OPC group objects) arrange the device association attributes.
(4) definition and interpolation OPCCItem object (OPC item object) arrange the device association attributes.Namely as the main interface of opc server, the IOPCServer interface is responsible for creating OPC Group, and returns other interface pointer, guarantees the interface function that client can invoking server.OPC client can add the OPCItem object of some by the OPCGroup object reference IOPCItemMgt interface of creating.
(5) the DataChange event of triggering OPC group objects, the i.e. read-write operation of data.Particularly, come the value of each Item object among synchronous or the asynchronous write OPCGroup by the member function Write that calls IOPCSyncIO or IOPCAsyncIO2.For reading of data, the unified subscribing manner that adopts of this supervisory system is monitored each process variable in real time.
(6) data item that changes is informed client.
(7) remove the OPCItem object.
(8) remove the OPCGroup object.
(9) disconnect and being connected of OPCSever object.
(10) eliminate the OPCSever object, discharge resource.Be that client discharges all interface pointer and deletes OPCItem, OPCGroup and OPCServer object successively when withdrawing from.
In further embodiment of the present invention, client can be synchronously or/asynchronous mode writes data to opc server, client also can be by the mode of subscribing to from the opc server read data.Wherein:
The data access mode
In the supervisory system of upper strata, client and opc server comprise two aspects alternately: one is that client reads data from server, and one is that user end to server is write data.In the OPC standard, the data access of opc server and OPC client (being client) has three kinds of modes: synchronous, asynchronous and subscription.Among the present invention, client is write The data synchronous write and asynchronous write to opc server.For reading of data, the unified subscription formula that adopts.
(1) synchronization of access mode (as shown in Figure 4)
Under the method for synchronization, the OPC client is by calling interface function access opc server, and opc server is according to the request search data item of OPC client.After search was finished, opc server sent the result to client.The OPC client is being waited for always before returning, and namely customer's call function runs to writing of all data always and finishes.
(2) asynchronous access mode (as shown in Figure 5)
Under asynchronous system, the OPC client sends request to opc server, and this operation is arranged, and function returns immediately so that client can be proceeded other operations.Each operation is regarded as one " things ", and a things ID is arranged.After operation is finished, produce a readjustment.In the information of readjustment, indicate things ID and operating result.Unique things ID is produced by the client, and returns to the client in readjustment, is used for guaranteeing return data correctly.
OPC client executing asynchronous feature more complicated, but quite effective.It can be operated the bigger data of quantity CPU and network resource consumption are reduced to minimum simultaneously.
(3) subscribe to formula access mode (as shown in Figure 6)
Subscription formula access mode comes down to a kind of of asynchronous data access mode, but different with above-mentioned dual mode, and subscribing manner can only read the data of opc server and can not write data to opc server.
In whole process, the OPC client needn't send request to opc server, but server periodically scanning buffer data and upgrade among Cache(the present invention, the scan period is defined as 500 milliseconds).If data change or change above certain limit, just notify client and send data, thereby make the OPC client can obtain the data that opc server sends automatically.The variation range that limits data is called as the dead band, the setting of can being correlated with.
Write operation for the significant data in the native system (for example technological parameter and system configuration information) adopts synchronous mode OPC data WriteMode, correctly arranges to guarantee each parameter, can not omit.For the write operation of general variable, can suitably select asynchronous system OPC data WriteMode for use, to reduce the consumption of CPU and Internet resources, guarantee the real-time of system.Than the method for synchronization and asynchronous system, subscription formula data acquisition modes can reduce the number of times of client-access server effectively, make the consumption of CPU and Internet resources drop to minimum, simultaneously can carry out lot of data, and farthest avoided the situation of network congestion, therefore very big advantage is being arranged aspect the data monitoring of big data quantity, and for the reading of data, the unified subscribing manner that adopts of this supervisory system is monitored each process variable in real time.
Client OPC Data access module implementation method
In translation and compiling environment, realize the OPC client applications, at first should can official website download OPC header file (opccomn.h, opccomn_i.cpp from the OPC international fund, opcda.h, opcda_i.cpp, OpcError.h, OpcPre.h OpcPre.cpp), and loads in engineering.In client OPC Data access module, self-defined OpcClient class, OpcPublic class and COPCDataCallback class (class name and function name definition in addition in the literary composition).
1.OpcClient class
In the OpcClient header file, number and the basic data type of definition OPC item.In source file, realize the main method of visit opc server successively, i.e. the connection of opc server and disconnection, and synchronous/asynchronous is write etc.In the data write method, at different data types, can realize bool type data write method respectively, float type data write method and int type data write method.For the dirigibility of data access, the present invention has also realized the data write method of array type, i.e. a plurality of data of the same type of write-once are to make things convenient for the processing of data.
1.1 connect opc server function C onnectServer;
ConnectServer mainly be responsible for to realize being connected of client and server, and sets up OPC group and OPC item, and specifically performance history can be carried out according to the following steps:
Initialization COM storehouse;
Utilize function C LSIDFromProgID (L " OPC.SimaticNET " , ﹠amp; Clsid) ProgID is converted into CLSID.Each com server has the ProgID of a character string type, can obtain globally unique CLSID by ProgID by the CLSIDFromProgID function.For example, the ProgID among the present invention is OPC.SimaticNET;
Utilize an OPC Server of CoCreateInstance function creation class example, obtain a pointer variable of pointing to the server object interface;
With IOPCServer interface method AddGroup interpolation group.In the parameter of returning, obtain pointing to the pointer of required process group object IOPCItemMgt interface;
Defined item arranges each corresponding address, routine m_Items[41 one by one] .szItemID=L " S7:[S7connection_1] MX954.6 ".For the array variable of continuation address, only first address is composed to this and got final product;
With the AddItems method of IOPCItemMgt interface whole are added in this group, and detection readable writing whether;
Obtain the IOPCGroupStateMgt interface, and inquiry synchronous versus asynchronous mode;
Set up subscribing manner, reading needs the data monitored item.
1.2 disconnect opc server contiguous function DisconnectServer;
DisconnectServer is responsible for finishing the communication of OPC client and server.In DisconnectServer, need remove (calling the RemoveItems function) successively, discharge synchronous, asynchronous and IOPCItemMgt interface (calling each Release function), remove group (calling the RemoveGroup function), discharge server (calling the Release function), and in the end call the CoUninitialize function and nullify the COM storehouse.
1.3 write method
According to different types of data, realize (or asynchronous) write method synchronously respectively, so that in program development process, the access mode of data is more clear and be easy to check.The present invention has mainly realized three kinds of modes that synchronous (or asynchronous) write, comprise bool type data write method SyncWriteBool (int ItemNo, bool ItemValue)/AsyncWriteBool (int ItemNo, bool ItemValue), float type data write method SyncWriteReal (int ItemNo, double ItemValue)/AsyncWriteReal (int ItemNo, double ItemValue) and int type data write method SyncWriteInt (int ItemNo, int ItemValue)/AsyncWriteInt (int ItemNo, int ItemValue).Wherein, first formal parameter list show by assignment to as if the group in which, second formal parameter list shows the value that will compose.For array variable, i.e. continuous variable of the same type can be by SyncWrite (int ItemNo, void*ItemValue, type ValueType, int ValueNo)/AsyncWrite (int ItemNo, void*ItemValue, type ValueType, int ValueNo) realize writing function, wherein shape ginseng ItemNo represent in the group which, the value that ItemValue indicates to compose, ValueType represents data type, and ValueNo represents the variable number.
Be example with the synchronous write function, in function body, according to data type access mode divided earlier, set gradually every property value (comprising data type and value etc.) according to shape ginseng content again.If the use method of synchronization need be called the Write function of IOPCSyncIO.If the use asynchronous system need be called the Write function of IOPCAsyncIO2.
2.OpcPublic class
Because this supervisory system adopts subscription formula data read mode to unify all parametric variables of reading system, so need special definition OpcPublic class to be responsible for temporary every process variable.Other classes all can be called such, to read each member variable in the class.Because each member variable of OpcPublic class is brought in constant renewal in, so satisfied the needs of data in real time monitoring.
During each member variable in definition OpcPublic class, should consider the data type of OPC item, to make things convenient for the processing of data.For example, for the OPC item of bool type, if go to read with the variable V ariant of QString type.When the OPC item was true, Variant was " 1 "; When the OPC item was false, Variant was " 0 ".
3.COPCDataCallback class
The COPCDataCallback class is to read the key of each OPC data item in this supervisory system, and it has inherited CComObjectRoot class and IOPCDataCallback class.The work of reading of all monitored variablees all realizes in member function OnDataChange.OnDataChange is for the treatment of the notice of OPC group objects, and this notice is carried out automatically by opc server when data change.
In the realization of subscribing to formula data access mode, will read mode according to the data type of each OPC item and segment.The numbering of OPC item of utilizing the member variable of OpcPublic class finds the item of self correspondence, thereby realizes reading of data.
Except needs are realized OnDataChange, also need realize OnReadComplete, OnWriteComplete and OnCancelComplete function among the OPCCallback.Wherein OnReadComplete and OnWriteComplete are for the treatment of the notice of finishing about the asynchronous operation read-write from the OPC group objects.OnCancelComplete for the treatment of from the OPC group objects about cancellation asynchronous operation completed notice.
The user interface of supervisory system
User interface is the important component part of supervisory system, but and is unique operation part that the technologist can intuitively see.The technologist is undertaken alternately by interface and system, with all parameters of real-time monitoring system, and carries out operations, and the assurance security of system is effectively moved.The present invention adopts a C++ kit for the cross-platform graphical interface program of exploitation of Qt() set up and be convenient to the graphic user interface that the technologist operates.The technologist can carry out every routine operation to the semiconductor equipment after entering the interface.According to the general function demand of equipment, user interface mainly comprises function (see figure 7)s such as editor, configuration, maintenance, supervision and help.In each functional module,, should be carried out the secondary of this module and divide by operand (for example technique unit 2 and technique unit 1 etc.) according to specifically, obtain different submodules, to make things convenient for technologist's use.At each submodule, according to its functional requirement, design corresponding sub-interface.Enter a certain sub-interface if desired, click in the drop-down menu of main interface corresponding and get final product.In addition, owing to adopt the form of menu, made things convenient for follow-up function expansion, so can easily new sub-interface (submodule) be joined in the menu at main interface.State-variable in the interface and bottom address keep one-to-one relationship, have guaranteed the real-time control of equipment and collection and the demonstration of status data.
Be example with the maintenance module, but the technologist utilize each unit module of maintenance module manual operation.Constitute according to equipment, be divided into technique unit 1, technique unit 2 and three sub-interfaces of EFEM, be respectively applied to debug corresponding unit.By each sub-interface, the technologist can operate each action of each unit, each parameter of each unit is set, and reads each variable of each unit.All interface controls all have corresponding label prompting, avoid technologist's operating mistake.
