JPH04105101A - Abnormality processing form setting method for controller - Google Patents

Abstract

PURPOSE:To simplify the operations of users by displaying the types of abnormality and the settable processing forms of each type of abnormality on a display screen in the form of a menu and selecting a certain processing form to each abnormality. CONSTITUTION:A controller 1 includes a CPU 2 serving as the nucleus of control and arithmetic operations, a memory 3 which stores the programs and data, and an operation part 4 which performs the input of data. Then a display device 5 and an abnormality output part 6 are connected to the controller 1. The types of abnormality and the settable processing forms of each type of abnormality are displayed on the display screen of the device 5 in the form of a menu. Thus a certain processing form is defined to each abnormality. Thus it is possible to freely define a desirable processing form at the user side in response to each type of abnormality without increasing the load of the user.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an abnormality processing form setting method for setting a processing form for various abnormalities occurring in a control device according to the type of the abnormality. .

<Prior art> When an abnormality occurs in a control device, what kind of abnormality processing should be performed is determined by the manufacturer's uniform definition of a predetermined processing form depending on the type of abnormality, or by the user's own program etc. Either create a system and define a unique processing format depending on the type of abnormality.

<Problems to be Solved by the Invention> In the former method, since the processing form for an abnormality is defined based on the manufacturer's standards, the processing form may not match the user's requirements. For example, if the setting is such that the abnormal output is sent to the outside via the abnormal output unit in response to the occurrence of an abnormality that is not particularly relevant to the user, the user needs to perform processing to handle the abnormal output. arise. Although the latter method has the advantage of allowing the user to define the desired processing format, it also requires the user to create a fairly detailed program, which poses the problem of increasing the burden on the user.

This invention was made with attention to the above problem, and provides a method for setting an abnormality processing form in a control device that allows the user to freely define a desired processing form according to the type of abnormality without increasing the burden on the user. The purpose is to provide.

<Means for Solving the Problems> The present invention is an abnormality processing form setting method for setting a processing form for various abnormalities occurring in a control device according to the type of the abnormality, and Displays a menu on the screen that shows the types of abnormalities and the processing forms that can be set for each type of abnormality, and selects one of the processing forms from the menu to define the processing form for each abnormality. That's what I do.

<Operation> The display screen displays a menu with the types of abnormalities and the processing forms that can be set for each type of abnormality, so the user simply selects one of the processing forms from the menu. The processing format for each abnormality can be defined as desired.

<Embodiment> FIG. 1 shows the configuration of a control system in which the present invention is implemented. In the figure, 1 is a control device in, for example, an image processing device, and a CPU 2 is the main body of control and calculation.
, a memory 3 for storing programs and data, and an operation section 4 for inputting data. The operation unit 4 is configured with a keyboard, a mouse, etc., and is used for menu selection of abnormality processing modes, which will be described later.

A display device 5 and an abnormality output section 6 are connected to this control device 1 . The display device 5 is a CRT, liquid crystal display, or the like, and displays a menu for selecting an abnormality processing mode. The abnormality output unit 6 is for, when an abnormality occurs in the control device 1, outputting an abnormality output for a predetermined abnormality to notify the outside.

FIG. 2 shows a menu 7 for selecting an abnormality processing mode displayed on the display screen of the display device 5. As shown in FIG.

In FIG. 2, numeral 8 indicates a display column listing the types of abnormalities, and numeral 9 indicates a display column listing the processing forms that can be set for each type of abnormality. Then, one of the processing forms is selected from the display column 9, and thereby, for each abnormality occurring in the control device 1, the processing form for the abnormality is defined according to the type of the abnormality.

In the figure, in the abnormality type display W8, rRS-
232C error" indicates an error in data transmission, and "rCPU error" indicates an error in control operation of CPU2.
"Parameter abnormality" refers to abnormalities in various parameters (e.g. sampling period for measurement, threshold value for judgment), "measurement abnormality" refers to abnormalities in measurement data (e.g. measured values such as area), "camera abnormality" ” and anomalies in image input, respectively.

In addition, in the abnormality processing form display 119 in the figure, "ignore" means that no special processing is performed for the abnormality. ``Message'' displays a message to that effect on the display device 5 in response to an abnormality, and ``buzzer'' generates an alarm sound.

"r terminal" sends an abnormal output to the outside via the abnormality output unit 6 in response to an abnormality, and "stop" stops the control system in response to an abnormality.

On the user side, prior to the operation of the control device 1, the above-mentioned menu 7 is displayed on the display screen of the display device 5, and the desired abnormality processing is selected for each abnormality by operating the operation unit 4. This indicates the selected abnormality processing form. For example, if it is an R5-232C abnormality, a message to that effect is displayed on the display screen of the display device 5 and an alarm sound is generated.

FIG. 3 shows an abnormality information table TB for storing information defined by the above menu selection.

In table TB in the same figure, for n types of abnormalities, 0- n
-1 is assigned to each abnormality number. This table T
In B, the abnormality type storage area 11 stores data indicating the name of the abnormality type, and these data are used when displaying the menu 7 on the display device 5. The processing form storage area 12 stores processing form data representing the processing form for each abnormality. This processing mode data is data having a width of several bits, each processing mode is assigned to each bit, and if that bit is "1", the processing of that processing mode is executed. For example, in the illustrated data, the bit of Do, which is assigned a meaning of "ignore", is "0", and the bit of Dl, which is assigned a meaning of "message", is "1", so when the abnormality occurs, the display device 5 The message will be displayed on the display screen.

FIG. 4 shows a control procedure by the CPU 2 of the control device 1 in response to the occurrence of an abnormality.

If some abnormality occurs in the control device 1 at the start time, in step 1 (indicated by rsTIJ in the figure), the CPU 2 checks the corresponding abnormality number depending on the content of the abnormality. Next is Ste.

In step 2, the CPU 2 reads processing mode data corresponding to the abnormality number from the abnormality information table TB. Then, in step 3, the CPU 2 executes abnormality processing according to the state of each bit of the read processing mode data.

<Effects of the Invention> As described above, the present invention displays on the display screen the types of abnormalities and the processing forms that can be set for each type of abnormality in a menu, and selects any processing form from the menu. Since the processing form for each abnormality is defined by selecting , the user can define the desired processing form for each abnormality through a simple menu selection.

Moreover, since no special work such as creating a program is required on the user's side, there is no increase in the burden on the user's side, and the invention has the remarkable effect of achieving the purpose of the invention.
