Abstract

PURPOSE:To execute plural tasks generated in different languages by providing functions of an interpreter, compiler, etc., and a working area for converting languages into an executable form in a controller. CONSTITUTION:When the operation of the controller is started, the kind of a language and a working area for language conversion are set for every task. When another task is started by a request from the task, interruption casused at specific intervals of time, or insterruption from another device, or when an interrupted task is restarted, a monitor program starts a task generated in machine language as it is on the basis of initially set data and starts or restarts a task generated in BASIC by starting the interpreter and interpreting the BASIC language in its working area.

Description

【発明の詳細な説明】 この発明は、制御装置において、複数のタスクを実行さ
せる方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for causing a control device to execute a plurality of tasks.

従来、この種の装置として、第１図に示すものがあって
、図面中の各タスクは機械語で作成されており、モニタ
プログラムの管理下にある。Conventionally, there is a device of this type as shown in FIG. 1, in which each task in the drawing is created in machine language and is under the control of a monitor program.

の切り換えを行う。Next, the operation will be explained. Each task is started or restarted by the monitor program, executes processing, and returns to the control of the monitor program when the processing ends or when the processing is interrupted until a certain restart factor occurs. Interruptions at fixed time intervals or interrupts from other devices request the monitor program to start or restart a certain task. Furthermore, a task that is currently executing a process can issue a request to start or restart another task that is stopped. The monitor program starts and restarts a task that has been requested to start or restart due to an interrupt, etc., and when it returns from that task, starts or restarts other tasks that have requested startup or restart, one after another. Switch tasks.

点があった。Conventional task execution methods for multitasking control devices use the method described above, and each task program must be created in machine language, and high-level languages cannot be used, making it very time-consuming to create programs. The disadvantage was that it took a lot of time.

ク実行方法を提供することを目的としている。It is an object of the present invention to provide a task execution method for a multitasking control device that makes it possible to execute a plurality of tasks created using FORTRAN or the like.

以下、この発明の一実施例を第２図により説明する。An embodiment of the present invention will be described below with reference to FIG.

この第２図における各タスクは、機械語、ＲＡＳＩＣな
どで作成されている。Each task in FIG. 2 is created in machine language, RASIC, or the like.

そしてその動作について説明すれば次の通りである。The operation will be explained as follows.

制御装置の動作開始時（初期時）に、言語の種類および
言語変換用作業領域を各タスクに対して設定しておく。When the control device starts operating (initial time), the language type and language conversion work area are set for each task.

、保守の容易なものが得られる効果がある。As described above, according to the present invention, the control device is configured to have functions such as an interpreter and a compiler, and a work area for performing these functions for each task. Tasks that perform processing can be created in machine language, tasks that process numerical data can be created in a high-level language, and tasks can be created in the language that is most suitable for the processing content, making task programs easy to create and maintain. There is an effect that can be obtained.
