CONSTITUTION:The need to generate individual programs by respective controllers 3 connected through the data transmission line 2 is eliminated by providing the program optimization processor 1 which gathers information showing what kind of processor and input/output port each controller consists of, selects at least one of previously stored optimized programs, and generates an optimized program characteristic to the controller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optimization processing device for optimizing each program of a plurality of control devices connected via a data transmission path.

[0002]

2. Description of the Related Art Conventionally, in this type of system, if the control devices connected to one data transmission path have exactly the same configuration, each control device can execute a predetermined function with the same program. Since the types of main processors and the specifications of input / output ports are often different, there are many cases in which a dedicated program is created for each control device to deal with it.

[0003]

As described above, since a program unique to each control device is used, not only does it take a long time to create a new program, but it is also necessary to change the constituent elements and functions of the control device. However, there is a problem that it is not possible to respond smoothly. Therefore, an object of the present invention is to provide an optimum program easily and in a short time to a plurality of control devices connected to one data transmission path.

[0004]

In order to solve such a problem, according to the present invention, a plurality of control devices having a processor and various input / output ports and connected to a data transmission path are provided in common. Component information indicating what kind of processor and input / output port is configured is collected from each of the control devices, and at least one of the optimization programs stored in advance is selected according to the collected component information. A feature is that a series of optimization programs is created for each control device, and the created series of optimization programs is transmitted to each control device.

[0005]

When a common program optimization processing device stores in advance an individual optimization program uniquely determined by the type of processor and the type of input / output port, and the actual operation such as when the power is turned on is not performed. In addition, it collects information from each control device as to what kind of processor and what kind of input / output port each consists of, so that a series of optimization programs can be created based on this, and a series of created optimization programs can be created. By transmitting the computerized program to each control device through the transmission path, it is easy to create a program that has been created individually for each control device, and the time for production is shortened.

The program optimization processing device 1 (MC) is commonly provided for the plurality of control devices 3 (C1 to Cn) connected to (L). This program optimization processing device 1 stores in advance individual basic programs that are uniquely determined by the type of processor and the type of input / output port. In addition, it has a function of collecting from each control device 3 component information indicating what type of processor and each type of input / output port each is composed of, and creating an optimized program based on this. There is.

FIG. 2 is a flow chart for explaining an operation example of a control device. First, in a step, data is input from the port A, subjected to a predetermined conversion and stored in a memory (step), and then a predetermined instruction is received from the control device 3 in FIG. 1, and the data is output to the port B ( Step).

Table 1 shows an example of constituent elements created by the program optimization processing device 1 based on information collected from the respective control devices 3 (C1 to Cn). For example, the control device C1 is a main processor type. Indicates that each element is composed of P1, the input / output port A type is S1, and the input / output port B type is R1. The table 1 is stored in a memory (not shown) in the program optimization processing device 1.

[Table 1]

Table 2 shows the type of main processor and specifications of input / output ports in the program management device 1.
An optimized program number (PN1, PN2 ...) Created for each component and one example of the component of each control device corresponding to the program are shown. For example, when the main processor is P1 and the input / output port is S1, the program PN1 corresponds, and when the main processor is P2 and the input / output port is R2, the program PN7 corresponds. Table 2 and program PN
1, PN2 ... Are also stored in the memory in the program management device 1.

[Table 2]

FIG. 3 is a flow chart for explaining the operation of the program optimization processing device.
The following is an example of the case where the above operation is performed. First, the program optimization processing device 1 collects information on constituent elements from each control device 3 via the data transmission path 2. This is summarized in Table 1 described above. Next, from Table 1, the components necessary for optimization (for example, P1, S
1) is extracted, and the optimization program is extracted from Table 2 based on the extracted components. Here, since the constituent element is the main processor P1 and the input / output port is S1, PN1 is selected as the optimization program (step). As a result, the steps of FIG. 2 are replaced with the optimization program PN1.

Since the next step in FIG. 2 is a step for performing a predetermined conversion on the input data, the optimization program is extracted with reference to Table 2. Here, since the constituent element is the data conversion of the main processor P1, PN10 is selected as the optimization program, and the steps of FIG. 2 are replaced by PN10 as shown in FIG. Further, since the step is the output of the converted data to the port B, the port B by the main processor P1 can be selected from
Since it is output to (R1), the optimization program P
N5 is selected and the steps of FIG. 2 are PN as shown in FIG.
Replaced by 5. Since the series of programs for a certain control device created in this way is given from the program optimization processing device 1 to each control device 3, each control device 3
Then, after storing the series of optimization programs in a predetermined memory (not shown), predetermined processing is executed based on the stored programs.

[0012]

According to the present invention, a program optimized for each control device is created by the program optimization processing device, and the created program is given to the control device via a transmission path. Not only is it easy to create a program that was originally created for each device, but also the time required for production is shortened.
