Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a computer output method (hereinafter referred to as a logging method) using an electronic computer.

FIG. 1 and FIG. 2 are diagrams for explaining a conventional logging method.

First, FIG. 1a shows the start-up sequence of the time update program 2. An interrupt signal generated at a constant period is given to the interrupt circuit 1 of the computer, which generates an interrupt, and the time update program 2 starts. will be activated.

Next, FIG. 1b shows an outline of the time update program 2.

This is a flowchart. When an interrupt occurs 51, the time is updated 5
2. Next, determine whether there is a periodic request for special logs 53
, Further, if there is a request, it is determined 54 whether it is a special log cycle, and then the special log program 3 is activated 5
50 After starting the special log program 3, the time update program 2 is returned to the interrupted program 560
In this way, conventional logging methods have only been based on time.

Further, FIG. 2 is a diagram for explaining a conventional special log program.

The special log program 3 has a log item input point reference table 31, an input point table 32, and an output data table 33, and the log item input point reference table 31 includes:
An input point index is stored that serves as an index for determining which input point is to be outputted as a log, and indicates the position of the data from the beginning of the input point table 32. The input point indexes are arranged according to the order of log printing. The input point table 32 stores the values of total human effort points measured by a computer and the values calculated based on the values of these input points.
In the special log program 3, first, an input point index is retrieved from the input point reference table 31 512;
Based on this, it is known where the required input point data is located in the input point table 32, and the data is brought from there.

The data obtained in this way is summarized at the end and output to the printing device, so it is temporarily stored in the output data table 3.
5140. In this way, when the check for all embossing items is completed S15, it is outputted to the printing device.

In the above system, since the storage items in the log item input point reference table 31 are fixed, there is a drawback that only predetermined items can be printed out, and furthermore, the log printing cycle is fixed. There was a drawback that it was difficult to make changes.

SUMMARY OF THE INVENTION An object of the present invention has been made to eliminate the above-mentioned drawbacks, and by providing a special log setting device, it is possible to easily change the storage items in the log item input point reference table, and to make it possible to easily change the storage items in the log entry point reference table. As well as allowing for changes;
The purpose is to provide a logging method that also allows group settings.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 3 is a diagram showing the configuration of the present invention.

In the figure, 4 is an electronic computer, 5 is a special log setting device, and 6 is a printing device. Plant signals are given to the electronic computer 4. Next, FIG. 4 shows a detailed configuration of the special log setting device used in the present invention and a flowchart of a program that operates according to requests from this device.

The special log device 5 consists of a function selection switch 51, an input point setter 52, a group setter 53, and a cycle setter 54.Furthermore, the function selection switch 51 uses the log item input point reference table 31 shown in FIG. It has the function of operating (special log item setting, special log item deletion) and the function of logging periodic request and cancellation request (special log request, special log cancellation). The logging method of the present invention will be explained below, mainly using FIG. 4 and also using FIG. 3.

When a request for setting a special log item or deleting a special log item is made, an interrupt is generated in the computer to determine which request is being made (S21), and if it is a request for setting a special log item, the input point setter 52 is The set input point is compared with the log item input point reference table 31 to determine whether it has been registered in the group set in the group setting unit 53 (S22).

If not registered, register the input point index to the specified group table in the log item reference point table 31 S23
do. If it is a special log item deletion request, the input point set in the input point setter 52 is compared with the log item reference point table 31 to see if it has been registered in the group set in the group setter 53 (S24).

If registered, the input point index will be deleted from the specified group table in the log item input point reference table 31.
25 will be given. In this way, the special log item setting and special log item deletion functions allow the storage items of the log item input point reference table 31 to be changed.

On the other hand, when a special log request or a special log cancellation request is made, an interrupt is generated in the computer to determine which request it is (S27), and if it is a special log request, the group set in the group setting device 53 The number is period setting device 5
At the cycle set to 4, it is determined whether logging is in progress at step S28, and if logging is not in progress, it is registered in the log item input point reference table at step S29. If it is a special log cancellation request, it is determined whether the group number set in the group setting device 53 is being logged (S30), and if it is being logged, it is deleted from the log item input point reference table (S31). As is clear from the above explanation, by adopting the logging method of the present invention, for example, by connecting a special log setting device to a computer that can read process signals, it is easy to change logging items. It is possible to change the logging cycle.
