Description

  The present invention relates to a system construction support apparatus, method, and program for supporting system generation of a process control system.

  In a process control system for controlling a manufacturing process in the steel industry or the like that requires high reliability by continuous operation for 24 hours, computers and networks dedicated to heavy electric manufacturers have been used so far. However, since there are difficulties in terms of cost reduction and expandability, specifications have been released in recent years, and the introduction of open systems using inexpensive general-purpose products is progressing.

  With the introduction of open systems, system generation for building process control systems is required. System generation refers to the operation of building a user-dedicated system that actually operates by selecting only necessary functions on the user side. In order for the developed application program to operate normally on the control middleware at the time of system generation, it is necessary to create a system generation information definition correctly.

  Here, the control middleware is a group of subroutines commonly used when a user creates a program, such as reading and writing data to a file, starting a program, and outputting an alarm message. A programmer who has no knowledge of the OS can easily create a highly reliable program by using this. The system generation information definition is definition contents required when an application program is executed on the control middleware, and registers a program to be executed, a file used in the program, and the like.

  However, there are many system generation information definition amounts and types to be defined, and if a definition omission or error (exceeding the upper and lower limits of the definition data, etc.) occurs, the frequency of system failure occurrence at the start of the process control system will increase.

  Therefore, the system generation information definition is created and checked, but the system development department has to do it because there is no longer the creation and checking mechanism by the heavy electrical equipment manufacturer. The creation and checking of the system generation information definition of the process control system requires a person who has sufficient knowledge about the control middleware and is familiar with the target system program mechanism to customize it for each target system. Therefore, the system developer first creates the system generation information definition, and then the control middleware developer checks it.

  However, although the system developer knows the contents to be defined for each target system, it is difficult to realize the definition accurately because the system developer is not an expert on the control middleware. On the other hand, control middleware developers who are responsible for checking the definition contents are familiar with the definition method, but it is difficult to check whether the definition has been accurately realized after fully recognizing the characteristics of each target system. It is.

  In addition, as a procedure for registering the system generation information definition in the process control system, the system developer creates a batch file for registration from the design document and application program necessary for generating the application program, and develops the control middleware. Checks whether the system generation information definition constraint has been violated, and executes the batch file on the process control system. That is, the registration batch file generates definition contents necessary for executing the application program on the control middleware in the control middleware management area.

JP-A-9-128016

  As mentioned above, while creating and checking system generation information definitions while creating a batch file for registration while checking design documents and application programs, it is inefficient and prone to omissions and errors. There was a problem.

  There is a need for a tool that can create and check system generation information definitions for process control systems and automatically generate batch files for registration without requiring specialized knowledge of system content and control middleware for system generation. Yes.

  As a technique related to system construction, for example, Patent Document 1 discloses a plurality of programs by performing operation definition and operation control of connection of tasks (programs) and enabling definition, registration, and deletion of files used by each task. Discloses a system construction method and apparatus that realizes a system that can operate under multitasking, and that automatically generates a program component configuration diagram and an inter-task activation transition diagram in a task as a document.

  However, Patent Document 1 discloses a configuration in which task definition data and file definition information are input via a screen. However, in terms of requiring specialized knowledge of system contents and control middleware, It is not a tool that can create and check system generation information definitions for process control systems and automatically generate batch files for registration.

  The present invention has been made in view of the above points, and an object thereof is to provide a tool capable of improving the efficiency and quality of system generation.

A system construction support apparatus according to the present invention is a system construction support apparatus that supports system generation of a process control system operated by an operating system, middleware, and an application program. The system generation support apparatus is generated from a design document necessary for generating an application program.
