[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a distributed control device that is devised to directly call a builder associated with an operation monitoring window of an operation monitoring station (hereinafter, HIS).
[0002]
[Prior art]
FIG. 13 is a functional block diagram showing a configuration of a conventional distributed control apparatus. Reference numeral 1 denotes a control bus, and reference numeral 2 denotes a higher-level HIS connected to the control bus 1 in the operation monitoring area (A). The operation is monitored by the operator 3 via the operation monitoring window 21.
[0003]
A subordinate field control station (hereinafter referred to as FCS) 4 is also connected to the control bus. Reference numeral 5 denotes an I / O bus, and the FCS 4 communicates with the host HIS 2 and communicates with the field device 6 in the plant area (C) via the I / O bus 5 to execute control.
[0004]
An engineering station 7 having a system generation function connected to the control bus 1 in the engineering area (B) is operated by the engineer 8.
[0005]
In the engineering station 7, various programs executed in the HIS2 and FCS4, control parameters, etc. System generation tool Generated by multiple builders and made into a database. Database information is downloaded to the HIS 2 and FCS 4, and predetermined operation monitoring and field device control are executed at each station.
[0006]
In the engineering station 7, reference numeral 71 denotes a builder, which includes a control drawing builder 71a, a function block detail builder 71b, a trend collection pen allocation builder 71c, and a graphic builder 71d.
[0007]
An engineering database 72 is constructed by referring to data defined by these builders, and includes a common database 72a, an FCS database 72b, and a HIS database 72c.
[0008]
The information in the FCS database 72b is downloaded to the FCS database 41 in the FCS 4. The plurality of functional blocks 42a, 42b, 42c in the FCS 4 refers to the data in the FCS database 41 and executes predetermined control.
[0009]
Information in the HIS database 72c is downloaded to the HIS database 22 in the HIS2. The control drawing window 21a, tuning window 21b, trend window 21c, and graphic window 21d in the operation monitoring window 21 in the HIS 2 are displayed with reference to the program of the HIS database 22.
[0010]
In the engineering station 7, reference numeral 73 denotes a system view (system generation function main body), which manages and manages the builder 71 and the engineering database 72 in a hierarchical manner and displays a builder file defined by the engineer and a system generation function for editing. Serves as the main window for launching.
[0011]
Reference numeral 74 denotes a project, which is the highest level of the hierarchy managed by the system view 73. A station 75 represents HIS2 or FCS4, and is a lower layer of the project 74. HIS2 and FCS4 data created by the system generation function is managed in units of stations 75.
[0012]
The builder 71 for executing a specific system generation work is at the lowest level of the hierarchy management of the system view 73 and is managed for each unit of the station 75. That is, a builder 71 is provided for each station. The control drawing builder 71a, the functional block detail builder 71b, the trend collection pen allocation builder 71c, and the graphic builder 71d shown in FIG. Builder that generated each window (hereinafter referred to as the related builder) It is.
[0013]
An engineer support device 76 managed by the system view 73 includes a name search device 76a that uses the file name of the builder as a key and a tag duplication definition inspection device 76b that checks for duplicate tag names.
[0014]
FIG. 14 is an image diagram for explaining an engineer's builder work mode in the engineering area (B). Reference numeral 81a denotes an engineer in charge of a function block, who is in charge of work of the control drawing builder 71a and the function block detail builder 71b. 81b is an engineer in charge of the trend, and is in charge of the work of the trend collection pen allocation builder 71c. 81c is a graphic engineer who is in charge of the work of the graphic builder 71d.
[0015]
[Problems to be solved by the invention]
As described above, the work in the engineering area (B) is premised on a division of labor system by engineers having specialized abilities, and generally has a configuration that does not show the scope of individual work. Therefore, in the engineering work, a worker of a certain builder does not need to see a builder outside the range, and of course, the engineering function cannot be seen directly from the operation monitoring machine area (A) side.
[0016]
In recent years, not only small-scale plants but also many large-scale plants have been labor-saving and multi-skilled, and there is a tendency to cover system definition and operation with a small number of people. In order to cope with this, it is necessary to quickly look at the target definition builder or reference builder from the operation monitoring machine area (A) side when correction occurs after the system operation is started.
[0017]
In the general operator role classification, the system view cannot be called. This is due to the design that the system restricts calls if the authority of the operator user on the operation monitoring side is not higher than that of the engineer. If the authority of the operator user is lower than that of the engineer, refer to the builder definition information. I can't.
[0018]
That is, in the general role classification of an operator, only the contents displayed in the operation monitoring window can be known, and engineering information (function block connection information and arithmetic expression contents) cannot be known. Furthermore, the system generation function cannot be activated in the read-only mode.
[0019]
The conventional procedure for an operator with user authority or higher to access a specific builder that defines a definition tag or graphic from the operation monitoring window is to return to the engineering function and call the system view. The only way to open a folder is to follow it.
[0020]
FIG. 15 is a functional block diagram showing a procedure for manually starting the builder by calling the system generation function from the operation monitoring window 21 of the HIS2. By selecting the system view 21g from the pull-down menu 21f displayed by clicking the tool icon 21e in the operation monitoring window 21, the system view 71 that controls the system generation function is called. Search for the file you want to refer to or change. After selecting, start the builder manually to access the corresponding builder.
[0021]
Such a procedure is cumbersome and it is impossible to quickly access the builder. The operator selects the corresponding graphic builder from the operation monitoring screen. Without starting hierarchical operation from the system view, the corresponding builder can be started automatically. If you can call it directly, search the function block tag name and call the builder directly as it is, or see the calculation formula of the function block, the efficiency of this work is considerably improved.
[0022]
In this case, regarding the direct call of the related builder from the operation monitoring operation screen, it is necessary to restrict the operation range according to the user authority of the operator who accesses the builder and to ensure the security inherent in the system.
[0023]
A first object of the present invention is to realize a distributed control device that enables even an operator with the lowest user authority to open a related builder in an engineering area with one touch from an operation monitoring window screen.
[0024]
The second purpose is to realize a distributed control device that can open the related builder directly from the search result of name search or tag duplication definition inspection using the function of the support device managed by the system view, or the quick builder activation device There is to do.
[0025]
The third purpose is a distributed type in which the security table is referred to when directly calling the relevant builder from the operation monitoring operation screen, and the operation range of the builder can be limited according to the user authority of the operator accessing the builder. It is to realize a control device.
[0026]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram showing an example of a distributed control apparatus to which the present invention is applied. The same elements as those described in the conventional apparatus of FIG.
[0035]
The first structural feature of the present invention is the builder calling means 23 provided in the HIS 2. Hereinafter, various calling modes including the builder calling from the HIS 2 by the builder calling means 23 will be described.
[0036]
(1) The most common calling form is that the builder calling means 23 passes the activation information from the currently displayed active operation monitoring window 21 to the system view 73 in the engineering station 7 and displays the activated builder information. It is a form that is downloaded to the HIS side for display and editing.
[0037]
(2) When the operation monitoring window is not active, the builder calling means 23 designates the name of the builder file to be called related to the operation monitoring window name by the operator and passes it to the system view 73 in the engineering station 7. The view is a form in which parameter information necessary for activation is acquired from the engineering database 72 managed by itself, the call target builder is activated, downloaded to the HIS side, and displayed and edited.
[0038]
(3) Call the system view from the operation monitoring window, pass the builder name information to be called as activation information to the builder name retrieval device 76a managed by the system view 73 in the engineering station 7, and activate the retrieved builder. It is a form that is downloaded to the HIS side for display and editing.
[0039]
(4) Call the system view from the operation monitoring window, pass the call target builder name information as activation information to the duplicate name retrieval device 76b managed by the system view 73 in the engineering station 7, and activate the retrieved builder. It is a form that is downloaded to the HIS side for display and editing.
[0040]
(5) Call the system view from the operation monitoring window, and pass the name of the builder to be called as the startup information to the quick builder startup means 76c newly installed in the present invention managed by the system view 73 in the engineering station 7. The downloaded builder is downloaded to the HIS side for display and editing.
[0041]
(6) For the operation by the operator for the builder downloaded to the HIS side, the security table downloaded from the engineering station 7 is referred to the HIS database 22, and the operator is based on the user authority registered in the security table. The operation range is limited.
[0042]
FIG. 2 is an image diagram of the builder direct call from the HIS 2 side by the builder call means 23 of the present invention. In the figure, the operator 3 is a system definition / operator involved in both the operation monitoring area (A) and the engineering area (B).
[0043]
The direct call image is the direct access indicated by the dotted arrow from the operation monitoring window 21 directly to the related builder for the root of the solid arrow indicating the hierarchical call from the top of the system view described in FIG. Further, the direct access indicated by the dotted arrow to the related builder is made based on the search result of the name search device 76a in the engineering station 7.
[0044]
FIG. 3 is a sequence diagram showing a mechanism for calling and downloading a related builder from the operation monitoring window in the present invention. Since the system view 73 manages and manages each builder, it is necessary to always start the builder from the system view.
[0045]
In step (1), the builder activation process of the builder calling means 23 is called from the operation monitoring window 21 or the like. The builder activation process processes parameters passed from the operation monitoring window.
[0046]
It is checked whether the system view 73 has already been started up (whether a system view process exists). If not, the system view is newly activated in step (2) with the parameter as an argument. If the system view 73 has already been started, a message is transmitted to the system view in step (3), and parameters are passed to the system view.
[0047]
Immediately after step {circle around (2)} or step {circle around (3)}, at step {circle around (4)}, a process completion return is returned to the operation monitoring window 21 and the process related to the call is finished. Since this process ends without waiting for the actual builder activation, the time is very short and does not burden the calling process.
[0048]
In response to the call of step (2), the system view 73 refers to the project data in the engineering database 72, determines which builder is to be activated based on the passed parameters, and uses the parameter analysis result to determine the corresponding builder. (For example, the graphic builder 71d) is automatically started in step (5). In response to the call of step (3), the system view 73 interprets the message content and automatically starts the builder at the corresponding step (5).
[0049]
When the corresponding builder is activated, it is downloaded to the operation monitoring window 21 in step (6), and the operator 3 can confirm the display contents of the downloaded related builder and perform editing operations. As an example of how to use, the calculation formulas of calculation-related functional blocks can be referred from the operation screen, can be referred directly by opening the definition builder from the graphic screen, and can be edited depending on the user authority.
[0050]
FIG. 4 is an image diagram showing the correspondence between the call of the related builder and the download. Through engineering related to the field device 6 in the plant area, the contents of the control drawing builder 71a, the functional block detail builder 71b, the trend collection pen allocation builder 71c, and the graphic builder 71d are defined and databased.
[0051]
In response to calling the corresponding builder from the control drawing window 21a, tuning window 21b, trend window 21c, graphic window 21d in the operation monitoring window 21, the related builder activated by the system view is downloaded and displayed, and the user authority It is edited according to.
[0052]
FIG. 5 is an image diagram of a screen for explaining the procedure of the related builder call operation from the active operation monitoring window. First, after activating the operation monitoring window 21, pressing a related builder call button in the tool box activates and displays a builder associated with the operation monitoring window (for example, the function block detail builder 71b).
[0053]
FIG. 6 is an image diagram of a screen for explaining a procedure of a related builder call operation in which a window name is specified. First, when the designated character FIC1000 BDR (“window name BDR”) is input in the Name input dialog, a builder associated with the operation monitoring window (for example, the function block detail builder 71b) is activated and displayed.
[0054]
FIG. 7 is a table showing a list of parameters passed to the system view 73 when a related builder is called from the HIS 2 side. The system view finds the corresponding builder based on this parameter and activates it.
[0055]
FIG. 8 is a table showing a list of parameters passed to the system view 73 when the related builder is called using the name search device 76a and the tag duplication definition inspection device 76b, which are engineer support devices on the engineering station 7 side. . The system view searches for the corresponding builder based on this parameter and activates it.
[0056]
The corresponding builder can be called from the search results of these devices. That is, function block details, control drawing (function block list), status display, and logic chart status display can be called from the function block tag name.
[0057]
In addition, it is possible to directly start the definition builder of each functional block, the drawing builder, the graphic builder, and the trend pen allocation builder that refer to it. With this function, it is possible to quickly go back and forth between definition tag names, global switches, IOM builder, and tag names referring to them.
[0058]
FIG. 9 is a folder tree view display diagram illustrating an example of a search range of the quick builder activation device 76c. The quick builder activation device 76c is a service newly added as an engineer support device in addition to the existing name search device 76a and the tag duplication definition inspection device 76b.
[0059]
The quick builder activation device 76c can directly call a builder that defines a tag name or the like as a key. At the same time as the designation of the name, the operator designates a range in which the name designated in the tree view is searched as shown in FIG. This name is passed to the system view 73 to request a process for calling a related builder, and the system view searches for the corresponding builder from the designated range and activates it.
[0060]
The present invention considers the security of the associated builder that called. If the role classification of the user does not have the builder write authority, the related builder is activated in the read-only mode. In general, it is an engineer's task to edit the system generation function, and thus it is normal that the write authority is not given to a general HIS operator.
[0061]
The feature of the related builder call according to the present invention is that a builder is started in a read-only mode for a general operator, and a builder is started in a writable mode for an operator with engineer authority.
[0062]
The security judgment at the time of calling the builder is automatically performed by the system by referring to the security table downloaded to the HIS database 22 when the builder calling means 23 is called, as shown in FIG. Thus, engineering security can be protected by considering the security of the builder.
[0063]
FIG. 10 is an example of a security table. HIS users are assigned a role classification. Authority for operation monitoring of the plant is defined for each role classification. The authority is a level such as a window monitoring level, a window operation level, an instrument monitoring level, an instrument operation level, etc. that can be used in the role. In the example of the figure, the authority level has 8 levels from value 1 to value 8, and the value 3 is assigned to the related builder call authority.
[0064]
Windows and instruments have levels, and only authorized role classification levels can be monitored. The role classification includes system-fixed S1 to S3 and U1 to U8 in which the user can freely define authority.
[0065]
FIG. 11 is a table showing an example of registered user names and role classifications. In this example, since the function authority for calling the builder is value 3, the user names OFFUSER (S1), ONUSER (S2), and TANAKA (U1) start the builder in the read-only mode. User names ENGUSER (S3) and SUZUKI (U3) start the builder in writable mode.
[0066]
FIG. 12 is a flowchart showing a procedure for calling a related builder with reference to user security. (A) is a builder call related to an active window, and (B) is a builder call flow in which a window name is specified. .
[0067]
In step S2 following the start of step S1, information on the currently active operation monitoring window is acquired in the flow (A), whereas information is acquired from the window name received from the argument in the flow (B). . The processing flow of the following steps S3 to S7 is the same.
[0068]
In step S3, it is checked whether or not the system generation function can be used. If the environment is usable, the current HIS security is acquired in step S4, and the security at the time of calling the builder is determined from the security table in step S5.
[0069]
In step S6, the related builder is called, and the process ends in step S7. If it is determined in step S3 that the stem generation function cannot be used, the process jumps to step S7 and ends.
[0070]
In this way, by referring to the security table, it is possible to call the related builder by one-touch operation by linking to the role classification of the user logged in to the HIS. Operation that does not lower the security level is possible even with the call operation.
[0071]
In the embodiment described above, the engineering station 7 is directly connected to the control bus 1, but may be configured to be connected to a general-purpose PC means arranged at an unattended remote point via a network. According to the environment of the present invention in which engineering can be performed from the HIS side, the engineering station side after startup can be unmanned.
[0072]
Further, in the embodiment, the builders 71a to 71d are shown as functions in the engineering station 7. However, each of the builders 71a to 71d can be configured by independent general-purpose PC means to communicate with the engineering station 7 via a network. .
[0073]
【The invention's effect】
As is apparent from the above description, the present invention provides the following effects.
(1) A related builder can be called with one touch from the HIS operation monitoring window. As a result, the operator can refer to the engineering information with a single touch without the hierarchical complicated operation from the conventional system view.
[0074]
(2) Since the security of the called builder is linked to the role classification of the HIS login user, the builder is started in the read-only mode by a general operator, so that the security degradation problem is solved.
[0075]
(3) Since the user who is an engineer starts the builder with writable security, it is possible to provide a total work environment on the HIS side from the engineering viewpoint.
[0076]
The total work environment is the operation monitoring window displayed on the HIS. If there is an incorrect definition, the related builder is started with a one-touch operation, the contents are changed on the builder, and the contents of the engineering database are overwritten and updated. This is an environment where the definition content is confirmed on the HIS.
