Things. A physical object template can hold information about the actual device it represents. For example, FIG. 3 is an example in which information of a device corresponding to the node 23 in FIG. 2 is described. The above-mentioned template describes a device used in a plant. In general, a machine that performs some function is configured by combining a plurality of devices. FIG. 4 is an example of a template of a physical object representing a device constituting a machine.
In the figure, the node 41 is “WB (WalkingBe
am) type conveyor ", and the node 42 indicates that the" solenoid valve (forward / reverse) "is one device constituting the machine. The template of the physical object described above is edited by the object editing unit 6 in FIG. 1 and stored in the template storage unit 5.

Next, how the machine defined as a physical object template behaves is defined as a functional object template. FIG. 5 is an example of a functional object template. The template of the function object is also structured in a tree shape. The node 51 represents “WB type conveyor” as a machine type, and indicates that it corresponds to the node 41 of FIG. 4 defined as a template of a physical object. How the machine operates is expressed by a unit operation representing a single operation and a machine operation combining the unit operations. The node 52 indicates that the child node is a unit operation, and the node 55 indicates that the child node is a machine operation. Node 5

In the unit operation in the template of the functional object, since a device that actually performs the operation exists, a link indicating which device performs the unit operation can be provided. FIG. 7 shows an example in which a link is provided from one of the nodes in the template of the functional object to one of the templates of the physical object. In the figure, node 71 is
The node is the same as the node 53 in FIG.
This is the same as the node 42 in FIG. By forming the link 73 between these two nodes, it means that the operation of “WB rise” is performed by a device called “solenoid valve (up / down)”. The template of the functional object and the link between the nodes described above are edited by the object editing unit 6 in FIG. 1 and stored in the template storage unit 5.

The template of the physical object and the template of the function object are so-called parts for realizing the function of a certain plant, and when applied to an actual plant, it is necessary to specialize or embody the plant. is there. FIG. 8 is an example of a physical object in which a template of a physical object is specially expressed for a certain plant. The figure means that the “WB type conveyor” shown in FIG. 4 is specialized as “No. 1 conveyor” of a certain plant. This specialization is performed in the following procedure. First, the user specifies a template of a physical object to be specialized and a specialized name to the object editing means 6 of FIG. The object editing unit 6 takes out the template of the specified physical object from the template storage unit 5, assigns a name specified by the user, and copies it to the physical object storage unit 1. Machines in a plant may have equipment for achieving more advanced functions in addition to the equipment defined as a template. FIG. 9 shows an example in which a device is further added after specializing a physical object template. In the figure, the nodes 91, 92 and 93 are referred to as “No.
This is an example in which a sensor for detecting whether an object is mounted on the "conveyor" is added. For the specialized physical object, it is necessary to further specify and actualize the equipment actually used in the applicable plant. For example, FIG.
0 is “No.1 conveyor” “solenoid valve (forward / reverse)”
FIG. 2 shows the use of the “MHI126H7” format defined as a physical object template in FIG. This realization is performed by linking, and in the figure, the node 101
The “solenoid valve (forward / reverse)” is linked by a link 103 to the node 102 “MHI126H7”.
This embodiment is performed in the following procedure. First, the user gives the object editing means 6 in FIG.
Specify the node of the physical object to be instantiated. Next, the user selects and specifies which device is to be embodied from the node of the template of the physical object.

FIG. 11 is an example of a function object expressing a template of a function object specifically for a certain plant. The figure means that the “WB type conveyor” shown in FIG. 5 is specialized as “No. 1 conveyor” of a certain plant. This specialization is performed in the following procedure. First, the user designates a template of a functional object to be specialized and a specialized name to the object editing means 6 of FIG. The object editing means 6 retrieves the template of the designated function object from the template storage means 5, assigns a name designated by the user, and copies it to the function object management means 2. Next, unit operation and machine operation are added to the specialized function object.
For example, in FIG.
The node 113 is obtained by adding an operation of detecting the presence of an object by a sensor, and the node 114 is obtained by adding a mechanical operation of another function object. Fig. 7
As described above, the node for the unit operation of the template of the functional object is linked to the node of the template of the physical object corresponding to the device that achieves the operation. The object editing means 6 in FIG.
When a template of a functional object is copied and stored in the functional object storage unit 2, the link between the objects of the physical object corresponding to the link destination node set on the template is set by the inter-object link management unit 4. Automatically. For example, since the node 115 in FIG. 11 corresponds to the node 71 in FIG. 7, the node 115 in FIG. 8 which is a physical object corresponding to the node 72 in FIG. Link is established. On the other hand, for a unit operation added when specializing a template of a functional object, it is necessary to link a physical object to a device that realizes the operation by a user's designation. FIG. 12 shows an example of linking a unit operation of a functional object to a physical object. In the figure, the unit operation “Skid 1 presence” corresponding to the node 121 is realized by the physical object “Sensor (Skid 1 presence)” corresponding to the node 122, and is linked by the link 123. I have.

The operation of the machine defined as a functional object is actually controlled by a program on a controller. FIG. 13 shows an example of a control object corresponding to a control program created for a certain plant. The control program is expressed hierarchically in a tree shape. In the figure, the program “No. 1 Conveyor Advance” indicated by the node 132 indicates that it is executed by the task “Task 1-1” indicated by the node 131. Since the control function performed by the control program corresponds to the operation performed by the machine in the plant, a link can be established between the control object and the function object.
FIG. 14 shows an example in which a link is provided from a control object to a function object. The link 141 indicates that the “No. 1 conveyor advance” of the control object corresponds to the “forward” of the functional object.

As described above, in the first embodiment, the information of the device achieving the operation can be obtained from the control program by following the link.
For example, it is possible to follow the link provided to the control object “No. 1 conveyor advance” to reach “function advance”. The operation procedure shown in FIG. 6 is described in “Forward” of the functional object. For example, it is assumed that a unit operation “WB forward” is selected.
“WB forward” is linked to the “electromagnetic valve (forward / reverse)” of the physical object as shown in FIG. 7, and can reach the node 82 shown in FIG. Information of the device is stored in the node of the physical object. For example, the device number, the inspection date, the inspection result, the repair history, and the like can be referred to or updated. Further, as shown in FIG. 10, the physical object has a link to a node of the template of the physical object, and by following this link, it is possible to obtain information on the model of the device as shown in FIG. it can. Therefore, a link is established between a physical object that manages information about machine equipment in a plant, a functional object that manages information about operation of a machine in a plant, and a control object that manages information about a control program. , It becomes possible to derive the relationship between the control program, the operation of the machine, and the information of the machine device, and it becomes easy to perform debugging and maintenance work. In addition, since the configuration of equipment and machines and the operation of machines can be made into templates and edited for applicable plants to create physical objects and functional objects, it is possible to save the trouble of building information such as the operation of machine equipment and machines. Can be reduced. In addition, by linking between templated equipment and machine configurations and machine operations, and maintaining them when editing them for the applicable plant into physical objects and functional objects, linking can be performed manually.
