Description

  The present invention relates to an engineering technique, and more particularly to an engineering technique that supports creation of a control logic used in a control system.

  In large-scale facilities such as plants and buildings, the entire facility is managed by introducing a control system and remotely controlling various equipment installed in the facility with respective controllers. In such a control system, for each controller, load data indicating a control loop to be executed by the controller is created in advance by an engineering device, and the load data is loaded into the controller and set.

The control program for the control system is created by selecting a control block prepared in advance for each of various arithmetic processing functions and connecting input / output terminals of these control blocks via connectors.
In addition, after creating a control program, select a point object prepared in advance for each management point set for each equipment device, and connect to the input / output terminals of the control block. Work to create information is required.

  In such an operation, in an engineering device composed of an information processing device such as a server device or a personal computer, an operator operates a mouse or a keyboard on the screen to select an input / output to be connected or connected. Therefore, it takes time and effort to create a program, and it has become a factor that induces an operation error.

  Focusing on the fact that facilities with control systems introduced in the past, such as building floors, have facilities with almost the same configuration of control objects and the details of the control to be implemented. Templates are created in advance from applicable standard floor control programs, instances are created for each facility by duplicating this template, and each facility is partially modified as necessary to support each facility. A technique for creating a control program is proposed (see, for example, Patent Document 1).

  In addition, paying attention to the fact that there is equipment with almost the same point information content regarding the management points set in the equipment, not the identity of the contents of the control, representatives that can be commonly applied to such equipment Point information corresponding to each piece of equipment by creating an instance for each piece of equipment by duplicating this template in advance and making a partial correction for each piece of equipment as necessary. Has been proposed (see, for example, Patent Document 2).

Link information that defines the connection relationship between input / output terminals and equipment points must be created manually for each copy destination. For this reason, it takes time and effort, and it has become a factor inducing an operation error. In particular, when corrections such as point addition / deletion or type change occur, manual work to link the control program and point information resulting from the correction also occurs, so a huge amount of work is required to reflect the correction to each copy destination. There was a point.

[Effect of the first embodiment]
As described above, in the present embodiment, the template 20 and the control logic 24 are controlled so as to define the control logic for the equipment according to the control block corresponding to the arithmetic processing function used for equipment control and the connection state between the control blocks. The program 21 is composed of point information 22 that defines the combination and arrangement order of points used for equipment control and each point, and link information 23 that indicates the connection relationship between the control block 24 of the control program 21 and the points. It is a thing.

As a result, in addition to the control program 21 and the point information 22, the link information 23 indicating the connection relationship between the control program 21 and the point information 22 is collectively formed into a template.
For this reason, when creating the control program 21, the point information 22, and the link information 23 for each facility, it is possible to omit the manual work for connecting the control program 21 and the point information 22 that was conventionally necessary. Therefore, it is possible to greatly improve the work efficiency when creating the control program 21, the point information 22, and the link information 23 used in each facility.

Further, even if correction such as addition or deletion of points or type change occurs, the manual work for linking the control program 21 and the point information 22 due to the correction is greatly reduced. It can be reflected.
Furthermore, only by comparing the control logic 24 and the template 20 that is the source of the control logic 24, not only the difference between the control program 21 and the point information 22, but also the connection relationship between the control program 21 and the point information 22 are collectively displayed.

For this reason, if the operator performs logic verification on the template 20 in advance, only the differences that are presented for each control logic 24 created from the template 20 are configured to be specific to the equipment corresponding to the control logic 24. What is necessary is just to verify whether it matches, As a result, it becomes possible to improve the working efficiency regarding the logic verification of the control logic 24 significantly.

[Second Embodiment]
Next, with reference to FIG. 10, the engineering apparatus 10 concerning the 2nd Embodiment of this invention is demonstrated. FIG. 10 is a flowchart illustrating a control logic verification process according to the second embodiment.

In the first embodiment, the case where the control logic 24 selected as the verification target is verified by comparing the control logic 24 with the template 20 that is the basis of the control logic 24 has been described as an example.
Here, when facilities can be grouped in the similarity of configuration, the control logic 24 can also be grouped according to each configuration. For example, a room floor of a building is often similar in structure to other floors. Therefore, when verifying the control logic 24, the comparison with the reference control logic 24S as a reference in the group is smaller than the comparison with the template 20, and as a result, the number of items to be verified by the operator can be reduced. .

From this point of view, the comparison verification unit 18C according to the present embodiment includes a control logic 24 selected from the control logic storage unit 17 and a control logic created from the template 20 instead of the template 20. 24 has a function of comparing with a reference control logic 24S as a reference other than the control logic 24.

Subsequently, the comparison verification unit 18C compares the control information of the control logic 24 and the reference control logic 24S, and outputs the difference information 25 indicating the difference between the control information based on the obtained comparison result.

The difference display unit 18D displays the difference information 25 output from the comparison verification unit 18C on the screen display unit 13, thereby presenting the difference between the control logic 24 and the reference control logic 24S to the operator.
As a result, among the control information constituting the control logic 24 and the reference control logic 24S, the same part is automatically verified, and the part of the control logic 24 that is partially modified depending on the equipment is compared as a comparison result. The obtained difference is displayed on the screen.

  Therefore, a portion of the control logic 24 that requires logic verification can be appropriately presented to the operator. For this reason, if the operator performs logic verification of the reference control logic 24S in advance, the control is performed only for the presented differences with respect to each control logic 24 of other equipment similar to the configuration of the equipment of the reference control logic 24S. What is necessary is just to verify whether it matches with the structure peculiar to the equipment corresponding to the logic 24. As a result, it becomes possible to greatly improve the work efficiency regarding the logic verification of the control logic.

[Third Embodiment]
Next, an engineering device 10 according to a third embodiment of the present invention will be described with reference to FIG. FIG. 11 is a flowchart illustrating a control logic verification process according to the third embodiment.

In the second embodiment, the control logic 24 selected as the verification target is compared with the reference control logic 24S created from the same template 20 as the control logic 24, thereby verifying the control logic 24 as an example. As explained.
Here, depending on the control logic 24, although the original template 20 is different, the equipment configuration may be similar. In such a case, the equipment configuration is similar regardless of the template 20. Control logic 24 can also be grouped. Therefore, when verifying the control logic 24, compared with the reference control logic 24P created from the same template 20 and compared with the reference control logic 24P as the reference in the group, there are fewer differences, and as a result, the operator Can also reduce the number of items to be verified.

From such a viewpoint, the comparison verification unit 18C according to the present embodiment is replaced with the control logic 24 to be verified selected from the control logic storage unit 17 and the reference control logic 24S of the template 20 or the same template 20, It has a function of comparing with a reference control logic 24P created from another reference template 20P.
The difference display unit 18D has a function of displaying a difference between the control logic 24 and the reference control logic 24P obtained by the comparison in the comparison verification unit 18C on the screen.

That is, as shown in FIG. 11, the comparison verification unit 18C reads out the control logic 24 of the instructed template 20 from the control logic storage unit 17 based on the instruction operation from the worker detected by the operation input unit 12. The reference control logic 24P of the specified reference template 20P is read from the control logic storage unit 17.
Subsequently, the comparison verification unit 18C compares the control information of the control logic 24 and the reference control logic 24P, and outputs difference information 25 indicating a difference between the control information based on the obtained comparison result.

The difference display unit 18D presents the difference between the control logic 24 and the reference control logic 24P to the operator by displaying the difference information 25 output from the comparison verification unit 18C on the screen display unit 13.
As a result, among the control information constituting the control logic 24 and the reference control logic 24P, the same part is automatically verified, and the part of the control logic 24 that has been partially modified depending on the equipment is compared. Is displayed on the screen.

  Therefore, a portion of the control logic 24 that requires logic verification can be appropriately presented to the operator. For this reason, if the operator performs logic verification of the reference control logic 24P in advance, the control logic 24 of other equipment similar to the equipment configuration of the reference control logic 24P is not limited to the same template 20, It is only necessary to verify whether or not the presented difference matches the configuration specific to the equipment corresponding to the control logic 24. As a result, the work efficiency of the control logic 24 regarding the logic verification is greatly improved. Is possible.

[Fourth Embodiment]

FIG. 12 is an explanatory diagram of a configuration of an instance according to the fourth embodiment. FIG. 13 is an explanatory diagram illustrating a relationship between a template and an instance according to the fourth embodiment.

In the present embodiment, generation and correction reflection of an instance 30 which is a control logic 24 by duplicating the template 20 will be described.
There is a method of creating an instance by duplicating the same one as the template 20. In the present embodiment, the template 20 is not completely duplicated, but the same portion of the control logic 24 as the template 20 is not duplicated and taken into the instance 30 as it is. 20 is partially referred to.

[Instance generation method]
As shown in FIG. 12, the instance 30 includes reference data 30A indicating a reference relationship with respect to the original template 20, and difference data 30B indicating contents changed from the template 20 by the specification unique to the instance 30. Therefore, the control logic used when actually controlling the equipment with the controller is generated by applying correction to the entire data of the template 20 specified by the reference data 30A of the instance 30 using the difference data 30B unique to the instance 30. The

  The reference data 30A is parent reference data for referring to the template 20 from the instance 30, and includes identification information such as the template name and ID of the original template 20. When the instance 30 is generated, reference information indicating the template 20 that is a replication source of the instance 30 is registered as reference data 30A in the attribute information of the instance 30.

The reference data for referring to the instance 30 from the template 20, as shown in FIG. 12, managed by the instance management table 20T provided in each template 20. In this instance management table 20T, for each instance 30 copied from the template 20, an instance number unique to each instance 30 and a control target name indicating equipment controlled by the instance 30 are registered as a set.

Instance differential data
Even if there is no logical difference between the template 20 and the instance 30, a minimum difference consisting of the point address is generated as a basic difference. This is because the application controller of each instance 30 is different and its physical address is also different, so the corresponding I / O address is also different.
In the example of FIG. 13, in the point information 32 of the instance 30, “point: 1” and “point: 2” have no correction points from the template 20, but since there is a physical address setting, only that portion is added. This additional content (the bold line portion in FIG. 13) is registered in the difference data 30 </ b> B as a difference regarding the point information 32 of the instance 30.

In addition, after an instance 30 is generated based on the template 20, a function may be added only to a specific instance 30. In this case, the corresponding function addition content is registered in the difference data 30B of the instance 30.
In the example of FIG. 13, seasonal switching and valve change are added to the template 20 as the function addition unique to the instance 30.

In this case, for the addition of season switching, “point: 4” is added by the editing operation on the point information of the instance 30.
Next, the association between “point: 4” and “input terminal S” of “function block: SEL” is also added to the link information 33 by an editing operation.

In response to this, “input part: 3” indicating that “point: 4” is associated with the terminal of “function block: SEL” is displayed for the control program 31.
These additional contents (thick line portions in FIG. 13) are stored in the difference data 30B as differences between the point information 32 and the link information 33, respectively.

  Regarding the valve change, the control output destination valve is changed from the proportional valve to the ON / OFF valve by the editing operation on the point information 32 of the instance 30. Accordingly, in the point information 32 of the instance 30, the type of “point 3” is changed from “AO (analog output)” to “DO (digital output)”, and this additional content (the bold line portion in FIG. 13) is changed. It is stored in the difference data 30B as a difference unique to the instance 30.

[Apply modification of instance]
When any of the control program 21, the point information 22, and the link information 23 of the template 20 is changed, the modification of the template 20 is reflected in the existing instance 30 generated from the template as follows.
First, the instance management table 20T of the corrected template 20 is searched to identify each instance 30, and each difference data 30B of these instances 30 is checked.

  Here, when there is no correction other than the physical address included in the point information 32 and only the part common to each instance 30 in the template 20 is corrected, individual correction for each instance 30 is not necessary. This is because the content of the template 20 after correction is automatically reflected in the control logic 24 by the reference data 30A of the instance 30 as shown in FIG.

On the other hand, when the modification is reflected to the instance 30 having the unique modification other than the physical address included in the point information 32, it is confirmed whether the modification content of the template 20 matches the modification content unique to the instance 30 modified in advance. To do.
Here, if the two match, the correction contents overlap on the template 20 side and the instance 30 side, so the matching correction contents are deleted from the difference data 30B of the instance 30.

  If the two do not match, a screen display indicating that the correction contents do not match may be displayed to allow the operator to select which correction contents to reflect. At this time, a priority order may be set in advance for which correction content to be reflected between the template 20 and the instance 30, and either may be preferentially reflected based on this priority order.
