In the embodiment of the present application, it is necessary to which function library is divided into at least two subfunctions according to default division rule in advance
Storehouse, such as function library is divided with reference to industry control industry primary demand and user's specific demand etc., i.e., function library is divided into
Some independent subfunction storehouses, and the exploitation of function library and management are in units of subfunction storehouse.Wherein, subfunction storehouse specifically can be with
Including：A internal interface table, a external interface table and a piece of function code area.The internal interface list item of internal interface table is protected
The external calling interface information of cited external function is deposited, the external interface list item of the external interface table is built-in function
External calling interface information, the function code area are used to preserve subfunction place functional code logic entity.
It is the basic composition schematic diagram of the application neutron function library with reference to shown in figure 1.Wherein, each original subfunction storehouse
Including at least a internal interface table, a external interface table and a piece of function code area.In internal interface table, each inside connects
Oral thermometer item registers the external calling interface information of cited external function.When generating original subfunction storehouse by each internal work(
All external functions cited in energy are registered in the internal interface table, and establish built-in function and these internal interface list items
Adduction relationship, so that built-in function passes through these internal interface list item dereference external functions.In external interface table, each
External calling interface of the external interface list item as built-in function, is associated with built-in function one by one.Caller can only pass through
These external interface list items are called to access built-in function.Function code area：Current subfunction place functional code is deposited to patrol
Collect entity.
Wherein, the internal interface table in subfunction storehouse can directly deposit other word banks or the system that current subfunction storehouse is called
The external calling interface address of the function of offer.External interface table, which then houses, jumps to institute's functional in current subfunction storehouse
The jump instruction of code entry address.In original subfunction storehouse, the external calling interface of external function in internal interface table
Location is address blank, and the entry address deposited in external interface table is relative address of the function in book function library.
It is a kind of flow chart of the embodiment of the method for dynamic reference for realizing function library of the application with reference to shown in figure 2, this
Embodiment can specifically include：
Step 201：Function library is divided at least two subfunction storehouses according to default division rule.
Function library is divided at least two subfunction storehouses according to default division rule first, specifically may be referred to Fig. 1 institutes
Show.The subfunction storehouse is the code logic block for realizing one or more standalone features, and the subfunction storehouse can for example include：It is a
Internal interface table, a external interface table and a piece of function code area；The list item of the internal interface table preserves cited its
The external calling interface information of function in his subfunction storehouse, the list item of the external interface table are the function in book function library
External calling interface information, the function code area be used for preserve subfunction place functional code logic entity.
In the embodiment of the present application, function library can include：Subfunction storehouse concordance list and subfunction storehouse, the subfunction storehouse rope
Draw table and be used to preserve all effectively mark in subfunction storehouse and addresses in current function library, so can by subfunction storehouse concordance list
To realize record and the management to sub- function library.
Step 202：Increase, change or delete subfunction storehouse index entry newly in the concordance list of subfunction storehouse, and increase newly, change
Or delete subfunction storehouse corresponding with subfunction storehouse index entry.
It is the schematic diagram that subfunction storehouse index relative is established in the application with reference to shown in figure 3.For newly-increased subfunction
Storehouse, first, corresponding index entry is distributed in function library concordance list, the subfunction storehouse for only having manipulative indexing item in concordance list
It is only effectively, and allows cited in called program.Then, original subfunction storehouse is added to storage subfunction base area
Clear area.For the subfunction storehouse of renewal, such as Fig. 3, first, corresponding index entry is updated in function library concordance list, then,
By the original subfunction storehouse renewal after renewal to the relevant position of subfunction base area.And for deleting subfunction storehouse, then need
Corresponding index entry, while the corresponding subfunction storehouse for deleting storage in subfunction base area are deleted in function library concordance list.
In the embodiment of the present application, for addition subfunction storehouse, a subfunction is applied in function library concordance list
After storehouse index entry and space-consuming, the storehouse information in the subfunction storehouse is registered in the index entry of subfunction storehouse, subfunction can be included
Library name, ID, in the occupancy address of subfunction base area and length etc..After applying successfully, the correspondence in subfunction base area
Add the original subfunction storehouse in position.And for renewal subfunction storehouse, in function library concordance list corresponding to inquiry
Index entry, and update the storehouse information in the subfunction storehouse.If the length in the subfunction storehouse, need to apply taking sky again
Between, and index entry corresponding to renewal.If the length in the subfunction storehouse shortens, keep the base address in the subfunction storehouse constant,
And its space-consuming is reduced, update index entry corresponding to the subfunction storehouse.
Step 203：The subfunction storehouse listed in the index entry of the subfunction storehouse is compiled, relocated described per height
The external calling interface information of the function of each list item record in the internal interface table and external interface table of function library.
After each addition, renewal or deleting subfunction storehouse, by the external calling interface of cited function truly
Location is stored in the internal interface table, so as to establish the adduction relationship of built-in function and external function.Also, in external interface table
In also the external calling interface of these functions is relocated.That is, list item in the internal interface table in subfunction storehouse is relocated
The external calling interface information of the function of each list item record in content and external interface table.In the implementation process of this step,
Specific compilation process can include：
Step A1：The external interface list item in the subfunction storehouse that the caller calls is determined, so as to caller
The external calling interface information of the function in the subfunction storehouse is obtained, and by the function in the subfunction storehouse to transfering to other localities
The function in the subfunction storehouse is accessed with interface message.
In original subfunction storehouse, external interface table registers the entrance jump instruction of built-in function.With reference to shown in figure 4,
To realize that caller quotes the schematic diagram of built-in function by the external interface in subfunction storehouse in the application.Assuming that function A1 exists
Entrance relative address in the A of subfunction storehouse is 0x1000, at this moment external interface list item W1 content for " JUMP TO 0x1000 ",
Represent to jump at relative address 0x1000.
Specifically when relocating external interface table, according to absolute base of the current subfunction storehouse in subfunction base area
Location, the entrance relative address in each external interface list item is changed to absolute address.Referring again to shown in Fig. 4, it is assumed that external interface table
Item W1 content is " JUMP TO 0x1000 ", subfunction storehouse A absolute base address are 0x10000, then W1 content is changed to
“JUMP TO 0x11000”。
It should be noted that caller is when subfunction storehouse is quoted, if because the renewal of subfunction storehouse causes work(
It can be changed in the position in external interface table, then need to update the adduction relationship of all called programs, caller leads to
Corresponding function can be called by crossing access external interface list item, and the reference that otherwise need not change caller and subfunction storehouse is closed
System.Referring again to shown in Fig. 4, if caller needs to call A1, external interface list item W1 only need to be accessed, so as to jump to indirectly
Function A1 absolute entry address, so as to realize the reference to A1.If because the renewal in subfunction storehouse causes function in outside
Position in interface table changes, then needs to update the adduction relationship of all related callers, but is not required to the non-shadow of modification
Loud caller.Assuming that modification renewal occurs for subfunction storehouse A, function A1 external interface list item moves on to W2 from W1, then called
Program should access external interface list item W2 to quote A1.
Step A2：The list item of the internal interface table in the subfunction storehouse cited in the caller is determined, so as to son
Function library obtains the external calling interface information of the function in other cited subfunction storehouses, and passes through other described subfunctions
The function in other subfunction storehouses of the external calling interface message reference of function in storehouse.
In subfunction storehouse, the external calling interface that obtains the function in other subfunction storehouses by accessing internal interface table
Location, so as to dereference external function.With reference to shown in figure 5, be the application in by internal interface realize subfunction storehouse between adjust
Schematic diagram.Need to access external function B1 in subfunction storehouse A function A1, B1 is registered in internal interface list item N1
In, function 1 calls B1 indirectly by accessing N1.The adduction relationship with B1 is not yet established in original subfunction storehouse, N1 value is
It is empty.
, can be successively according to the outside registered in the internal interface table in subfunction storehouse specifically when relocating internal interface table
Function, the true address of the external call interface of external function corresponding to searching from current subfunction base area, and fill in
Into internal interface table.Referring again to shown in Fig. 5, it is assumed that external function B1 actual calling interface address is 0x20100, then interior
Portion interface entry N1 content is changed to 0x20100.
It is understood that in the case where external interface list item changes corresponding to current subfunction, in the application
, it is necessary to which the external interface list item after change is defined as into caller quotes current subfunction storehouse to realize current son in embodiment
The calling interface of function.
Step 204：Caller is compiled, to generate each subfunction that each caller and its are quoted respectively
The adduction relationship between function in storehouse.
Caller is compiled again after being finished to the compiling of sub- function library, drawn so as to generate each caller with it
The adduction relationship between function in each subfunction storehouse.
It can be seen that in the embodiment of the present application, by the way that function library to be divided into different subfunction storehouses, so as to by subfunction storehouse
The object quoted as caller, if only needing to use a sub- function library in industrial control system, then configuration software
Just only need compiling and download the information of a sub- function library, if any system functional block and function need not be used, just
It need not compile and download the information in any systemic-function storehouse.Therefore, the embodiment of the present application reduces compiling to a certain extent
With download content, so as to improve configuration efficiency, engineering construction process is also accelerated to a certain extent.Also, in function library
In function internal logic modification when caller will not be had an impact, it is not necessary to call routine recompilation download, this
Sample can also improve Project Configuration efficiency.
Further, because the extension in the application to function library and reference are in units of subfunction storehouse, on the one hand cause
Call subfunction storehouse and called subfunction storehouse relatively independent, the change in called subfunction storehouse is to calling subfunction storehouse not produce
Influence, on the other hand make it that caller and called subfunction storehouse are relatively independent, and increase and change subfunction storehouse to not
The caller being related to does not have any influence.This also causes the extension of function library and part to change very convenient, safety and practicality.
It can be seen that in the embodiment of the present application, during control system use, if the subfunction storehouse that increase is new, it is not necessary to
Any change is done to existing subfunction storehouse, it is only necessary to new subfunction storehouse is provided and can be achieved.If existing scene operation configuration exists
The use to new subfunction storehouse need not be increased in escalation process, then the system upgrade situation for increasing subfunction storehouse would not be right
The stable program operation in scene and production control produce any disturbance.Also, what's new, adjustment function in subfunction storehouse
The function that code, deletion are not used will not have an impact to existing caller, so as to ensure that the extension of function library
Convenience, safety and the practicality locally changed.
With the development of computer technology, the communication technology and control technology, traditional industrial control field just experiencings one
The unprecedented change in field, starts to develop to networking direction.In industrial control system, controller can be by performing calculating
Machine program realizes the use to all parts in industrial control system or setting.
If user triggers some request in actual applications, for example, being closed by performing corresponding caller
Valve etc..When user's trigger request, controller determines call corresponding with current request firstly the need of foundation current request
Program.Such as when user asks to close valve, it is determined that go out the caller of the corresponding function of realizing and close valve, triggering is closed
The caller of valve closing door is according to the function in subfunction storehouse corresponding to the corresponding relation calling determined.In practical application
In, function caller as corresponding to performing the controller in industrial control system of each request is realized, and caller institute
Function in the subfunction storehouse of reference is provided by each subfunction storehouse.
For foregoing embodiment of the method, in order to be briefly described, therefore it is all expressed as to a series of combination of actions, still
Those skilled in the art should know that the application is not limited by described sequence of movement, because according to the application, it is some
Step can use other orders or carry out simultaneously.Secondly, those skilled in the art should also know, described in the specification
