The editing process can be performed by the editing logic common to all editing devices.

FIG. 3 is used for the second embodiment in which the editing program loaded by the method according to the first embodiment is divided into modules of functional units and each module unit is loaded on the editing device. Explain.
The editing program 21 of the control device 2 includes a basic function module 211, an import (save) module 212, an editing screen display module 213, and an editing operation module 214.
-Compile module 215-Load module 21
6. A file input module 217, a file output module 218, and a monitoring module 219 are divided into functional units. The editing apparatus 1 includes a module unit required in the editing program 21, for example, a basic function module 121 and a save module 12.
2. The edit screen display module 123 is loaded into the editing device 1.

Each functional module has the following functions. Basic function modules 211, 121
Has a function of being taken into the editing apparatus 1 at the very beginning at the time of startup and managing other modules such as taking in and executing. The save modules 212 and 122 are the control device 2
It has a function of incorporating the above control logic 22 into the editing apparatus 1. Editing screen display module 213, 123
Has a function of interpreting the control logic and displaying the logic content on the edit screen. Editing operation module 214

The compile module 215 has a function of interpreting the edited result and converting it into a control lock. The load module 216 has a function of loading the control logic generated by the compiling function into the control device 2. The file input module 217 has a function of reading the contents stored in the storage medium by outputting the file. The file output module 218 has a function of writing the content being edited in a storage medium connected to the editing device 1. The monitoring module 219 has a function of displaying the execution state of the control logic executed on the control device.

These functional modules can be executed in units of each functional module, and the basic module 12 can be executed without loading all the functional modules.
It can be executed only by the target functional module such as three modules including 1, the edit screen display module 122, and the edit operation module 123.

The execution processing of the editing program by this method will be described with reference to the time chart of FIG. The edit start program was started by the user's edit execution operation (A), and the basic module was imported and started (B).
After that, the basic module (C) loads the save module (D), the edit screen display module (E), and the edit operation module (F) in this order by the save operation by the user, and executes the edit processing. After that, the basic module fetches the compiled module (G) by the compiling operation by the user and compiles it. Similarly, when the load operation is performed, the basic module loads (H) the load module and loads the edited control logic.

As described above, since the editing program is loaded in module units required for executing the editing process, the time from when the user performs the editing program starting operation until when the editing work can be actually started is shortened.

However, in the above method, when an operation for executing a function that uses a functional module that has not been imported into the editing device is performed, the function becomes available after the import of the functional module is completed. Therefore, it takes time for the import to be able to actually use the function.

Regarding the third embodiment for shortening the time from the function use operation when the function module not incorporated in the editing device in the second embodiment is used to the actual execution explain. Generally, a series of workflows can be assumed for editing work, such as screen display of control logic, editing, compilation, loading, and monitoring. In this embodiment, focusing on the characteristics of the above-mentioned editing work, when the user is using a certain function,
The function module of the next execution function is loaded first.

The outline of the functional configuration of the plant monitoring control apparatus according to the third embodiment will be described with reference to FIG. Third
The plant monitoring control apparatus according to the embodiment is characterized in that the editing apparatus 1 is provided with the next execution module table 16 and the control apparatus 2 is provided with the next execution module table 26.

The next execution function is stored in the next execution module table 26 provided in the control device 2, and the next execution module table is loaded into the editing device at the time of the save operation.
While executing the current function, the next execution module table 16 is referenced to determine what the next execution function module is, and the function module is loaded from the control device 2.

As shown in FIG. 6, the next execution module table is configured by specifying the functional module to be executed next in response to the user's operation. For example, when the user is performing an editing operation, it is expected that the compile function and the file output function will be used next time, so that the compile module and the file output module are loaded respectively. The next execution module table is arranged on the control device 2 and is loaded into the editing device by the basic function module when the editing program is started.

In the fourth embodiment, in the third embodiment, when there are a plurality of next-execution functions, the functional modules are loaded in order of priority, and the modules having higher priority are loaded in order. . It is determined that the priority of loading the functional module is higher in the order of the number of times the function is executed after the certain function is executed. This number of times is held in the execution module number table which records the number of times of execution of each function shown in FIG. 7. This table is arranged on the control device 2 and is taken into the editing device 1 by the basic function module when the editing program is started, and the basic function module collects and updates the change information when the function is switched during the execution of the editing work. Then, it is reflected in the control device 2 at the end of the editing program. As an example of the priority order and the import order, compilation and file output are expected next to the editing operation, but since the number of executions is 5 times for compilation and 11 times for file output, the file output operation has priority. Is high, the file output module is loaded first, and then the compile module is loaded.
Due to this, the function modules that are frequently used are loaded first, and when the user performs an operation, the import of the function module is often completed, and the import of the function module is executed after the user operates. Therefore, it takes less time to execute the function.

The fifth embodiment is different from the fourth embodiment in that an execution module number table that stores the number of times the function is executed is provided for each user and the function module is loaded according to the usage tendency of each user. It is a thing.
When an editing operation is performed by the editing device 1, the operating user has different operation tendencies depending on the designer, the inspector and the like. Therefore, the values stored in the execution module count table also differ. Therefore, an execution module frequency table is provided on the control device 2 for each user, and the editing device 1 fetches the table corresponding to the user for reference and updating. The user is identified by referring to the OS information when the operating system (hereinafter referred to as “OS”) installed in the editing apparatus has a user authentication function. O
If S does not have the function, the basic function module inputs the user ID to identify the user.
