[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system having a function of displaying the state of a controlled device and a function of controlling the operation of the controlled device. The present invention relates to an editor device for programming a control procedure and a recording medium on which an editor program is recorded.

[0002]

2. Description of the Related Art An industrial control device called a programmable logic controller (hereinafter, referred to as a PLC) or the like includes a hardware portion mainly including a CPU and a memory for realizing various controls including a sequence control. And a software part for controlling. The software portion includes designing a sequence control flow for operating the PLC according to the control system originally designed, converting the control flow into a command, writing the command to a memory, and the like. Generally, this series of operations is called programming.

[0003] In such programming, a proprietary language is used so that a program can be easily created without having specialized knowledge of a computer, and various programming languages which are easy for a user to use have been developed one after another. It became so. Currently, IEC (International Elect
The Rotechnical Commission) has established a standard programming language (IEC 61131-3). They are SFC (Sequential Function Chart), LD (Ladde
r Diagram), IL (Instruction List), FBD (Functio
n Block Diagram) and ST (Structured Text).

[0004] As described above, an environment is being prepared so that programs can be developed using various programming languages. For example, a ladder diagram (LD) has been widely used in the past because a ladder circuit can be designed relatively easily using a relay symbol, and is a programming language most often used at present.
As a programming tool used in a programming operation using such a programming language, a programming software such as a ladder editor has been widely used. Since this software can create a ladder diagram or the like in a form including symbols in a computer device such as a personal computer, it is easy to create and edit a program.

On the other hand, the programmable display has a dot display screen, an operation input switch, and a host controller (P).
LC), and an operation display having a program memory for control such as operation input on a screen. In general, a programmable display performs a graphic display, so that it can be provided with functions such as an operation panel, a switch, and an indicator light, and various monitors for management such as an operation status of a control target device and work instructions, It has a function as a terminal for inputting setting values for devices.

[0006] In recent years, a P / L is mounted by mounting an input / output unit or the like for connecting a device to be controlled.
Programmable displays with C control functions have also appeared.

A control screen (display content program) displayed on such a programmable display can be created by a user using screen creation software (drawing editor). When creating a screen, the user configures a desired control screen using parts (marks) such as switches, lamps, numeric keys, a meter display, a graph display, and drawing functions provided by drawing software on a personal computer or the like. I do.

The created control screen is transferred to and stored in the programmable display as screen data. PLC
During the operation of, the programmable display displays each component or graphic on the control screen according to the operation state of the control target device based on data exchanged with the PLC.

By the way, creation of a control procedure program using a ladder editor or the like (programming) and creation of a display content program using a drawing editor (screen creation).
Is generally performed independently. For example, when creating a display content program based on the created control procedure program, create design data in which the names and addresses entered for each device at the time of creating the control procedure program are written down in a table format. Then, a display content program including definition of an I / O address is created with reference to the design data. Similarly, when a control procedure program is created based on the created display content program, work is performed based on design materials prepared in advance.

On the other hand, Japanese Patent Application Laid-Open No. 8-263245 discloses a technique in which a symbol of a programmable display is displayed together with a ladder symbol on a common display by a ladder editor. According to this technology,
When a function that includes a graphic input parameter such as a touch switch is instructed, a function symbol such as a touch switch is displayed on the ladder screen. The ladder symbol is accepted and displayed on the ladder diagram. Thus, the creation of the ladder diagram and the creation of the screen of the programmable display can be performed simultaneously.

[0011]

However, in such a method, since a programmatic display symbol is created in the ladder diagram, a user who is proficient in creating the ladder diagram can easily perform a programming operation.
For users who are proficient in creating control screens for programmable displays but not ladder diagrams,
Programming becomes difficult. Also, in the above method, the ladder diagram and the symbol of the programmable display are mixedly displayed in the ladder diagram, so that a user accustomed to creating each of the ladder diagram and the control screen gives a sense of incongruity, There is a disadvantage that the working efficiency is reduced.

The present invention has been made in view of the above circumstances, and while inheriting the operability of a conventional editor,
If you are proficient in either programming such as ladder diagrams or creating control screens for programmable displays, an editor device and a record of editor programs that allow you to easily perform the other work along with that work It is intended to provide a medium.
