In recent years, there has been a control system in which a plurality of control devices operate in cooperation. In order to design such a control system, a control system design tool is used. In the control system design tool, a control program for causing a computer operation control device model is automatically generated, and simulation is performed on a virtual space, and the control device model is to apply a mechanism or an electrical signal in the control device. Formulator. With the execution of such a simulation, in the above-described control system design tool, the verification of the configuration of the control device and the verification of the control program can be performed in advance without verification using the real machine.

In Patent Document 1, an analog operation process for simulating the operation of the control device is executed in the simulation device of the analog control device. The simulation device collects the data of the shared memory stored in the CPU board at the start of the execution of the simulation operation process, and transmits it to the other device at any time point (timig) through the communication interface (interface). pay. Therefore, the integration of the data between the simulation devices is ensured.

However, in the PLC that executes the control program installed in the C language program, the component that stores the input/output data that is transmitted and received with the input/output device and the communication data that is received and received between the control devices cannot be performed. access. In such a PLC, it is necessary to access a component by using a dedicated component access function that differs depending on various types of components. Therefore, in such a PLC, only the correspondence between the variable name and the component storing the actual value is obtained. It is not possible to receive data with the input and output machines and communication devices. In such a PLC, it is necessary to describe the processing of the component-access function dedicated to the component that reads and writes the data in the control program, and there is a problem that the number of development man-hours increases.

Further, when the design of the control system is reviewed by the configuration or connection sequence of the simulation-side recombination control device while controlling the system design tool, the components for storing the communication data must be changed in accordance with the change in the connection order of the control device. Therefore, whenever the component is changed, the control program must be rewritten, so the development man-hours are further increased.

Further, the device to be controlled connected to the input/output device differs depending on each control device. Therefore, there is a problem that it is impossible to automatically generate a control program for component access including call processing of a component access function from the control system design tool.

In S1051, the component organizing unit 113 rearranges the component names with the same component name 202 so that the component numbers are in the numbering order, and generates a list 2020 of the variable names rearranged so that the component numbers are numbered. First, the component organizing unit 113 classifies the variable name 202 set in the management file 1071 into input and output of the input/output type. Next, the component organizing unit 113 uses the component name to classify the variable name for each type of component.

The component extracting unit 114 checks the continuity of the component number in a list 2020 of variable names for each type of component. The continuity of the inspection component number means that the number of components to be read or written is checked within a certain range of the component number (for example, 1 to 16, 17 to 32, 33 to 48, ...). As a result of the check, when a plurality of component numbers are allocated within a certain range, the access program generating unit 108 is instructed to integrate and use a dedicated function to read or write data.

In S106a, the access program generating unit 108 generates an access program 1083 that accesses a plurality of elements 230 corresponding to the plurality of variable names 202 by one function.

The process of reading after the data of the plurality of variable names 202 is integrated.

In the first embodiment, a function (for example, a getX function) for individually reading data for one variable name 202 is used. Since the input component X is a bit device, the data is read in the 1-bit unit of the getX function, but in the getWordX function, the word unit (16-bit) can be read. data. Therefore, in the first embodiment, in order to read the data of the component numbers 1, 3, 8, and 10 of the input component, the getX function is executed four times. However, in the present embodiment, as long as the getWordX function is executed once, Readable Enter the data of component numbers 1, 3, 8, and 10 of the component.

When the output element Y is allocated to the plurality of variable names 202, the same thinking method as the method of accessing the input element X can be applied.

Further, when the communication element L is allocated to the plurality of variable names 202, since the communication element L is a character element, the element extraction unit 114 determines that only when the element numbers are 1, 2, and 3 are completely continuous. Data can be written to the communication element L by using a function (for example, a WriteDatas function when data is written). The component extracting unit 114 notifies the communication access program generating unit 1082 of the result of the determination. In the function of reading or writing data to the communication element L, it is assumed that the component number preceding the communication element L for reading or writing data can be specified, and reading or writing is performed once. The number of characters in the data is used as an argument.

The new plurality of component numbers that are accessed are used as the recommended component numbers. The recommended component calculation unit 115 calculates the processing time of the current state of the process of accessing the component assigned to the variable name 202 as the current processing time 601 based on the inspection result of the component extraction unit 114. In the recommended component calculation unit 115, the processing time of each function (for example, a getX function, a WriteData function, or the like) is held in advance.
