Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is connected to an external device including a control device such as a programmable controller (also abbreviated as a PC) via a communication line to display the state of machines and equipment and to instruct setting values. The present invention relates to a so-called operation indicator (abbreviated as POD), and particularly to improvement thereof.

[0002]

2. Description of the Related Art Heretofore, this type of POD itself has been known. By the way, in such a POD, 1) recording is performed by a program (sequence) for monitoring the state of the machine / equipment. 2) For continuous tests and demonstrations of machines and equipment,
It is realized by creating and operating a program for that purpose. 3) It usually does not have the function of transferring operation data from POD to PC. Is normal.

[0003]

That is, the conventional ones have the following problems a) to c). a) A special sequence must be created to record the operations on the POD. Even if the machine / equipment becomes abnormal without preparing the operation recording means, there is no valid data for the subsequent investigation.

B) Sequences must be created by the PC loader even for temporary and simple operations / tests. c) In order to make the POD perform various movements (operation states) for a test or the like, it is necessary to instruct a worker or switch simulation software or the like. Therefore, an object of the present invention is to make it possible to easily obtain an operation record without using a special program, and to reproduce a machine / machine by reproducing the operation record.
It is intended to facilitate continuous testing and demonstration of equipment, and to improve the availability of recorded data.

[0005]

In order to solve such a problem, according to the invention of claim 1, a fixed screen which is connected to an external device including a programmable controller through a communication line and is stored in advance in the fixed screen. In an operation display device that can read out information to indicate the status of machines and equipment and instruct setting values, a record that indicates the start and stop of the operation of switches, numerical values, and character setting areas arranged in the fixed screen. The feature is that an instruction means is provided.

In the invention of claim 1, the recording instruction means can be arranged on a communication line with the external device (invention of claim 2), or the recorded data is stored in a predetermined memory area. However, it is possible to communicate with an external device by giving a predetermined instruction (invention of claim 3), and a reproduction instruction means for giving an instruction for reproducing the recorded data can be provided (claim). Invention of 4). Further, in the invention of claim 4, the reproduction instructing means can be arranged on the communication line with the external device (invention of claim 5).

[0007]

By making it possible to record the operation performed in the POD, it becomes convenient for later analyzing the situation of the machine / equipment. In addition, by making it possible to reproduce the operation record,
To be able to perform continuous tests and demonstrations of equipment. Furthermore, operation record data can be transferred from POD to PC.
Data availability can be improved by enabling transfer from other devices or PCs to POD.

1 is a conceptual diagram showing an embodiment of the present invention. In the figure, 1 is a POD, 2 is a PC, and 3 is a communication line. That is, the POD 1 is provided with a fixed screen 11, an operation record data processing unit 12, a screen data memory 13, an operation record data storage memory 14, and the like. In addition,
Here, only the parts necessary for the explanation are shown, and the others are omitted.

When, for example, the start switch 11A arranged on the fixed screen 11 of the POD 1 is pressed, the information to that effect is input to the operation record data processing unit 12, and the switches and numerical values in the fixed screen 11 thereafter are entered. All operations on the character setting area, etc. will be recorded.

Therefore, for example, if SW1 (startup) in the fixed screen 11 of the POD 1 is operated thereafter, the ON / OFF information is given to the PC 2 via the communication line 3 and, at the same time, via the operation record data processing unit 12. In the operation record data storage memory 14, information to that effect is stored together with the date and time at that time, for example, "SW1, ON, date time". After that, each time a switch, a numerical value, a character setting area, or the like in the fixed screen 11 is operated, the above processing is repeated.

To stop the operation recording, the stop switch 11B arranged in the fixed screen 11 of the POD 1 is pushed. This causes POD1 to return to normal operation. Therefore, even if a switch, a numerical value, a character setting area, or the like in the fixed screen 11 is subsequently operated, the operation record does not remain.

The data recorded in this way is recorded in POD1.
Playback switch 11C arranged in the fixed screen 11 of
Play by pressing. That is, the reproduction switch 1
When 1C is pressed, the information indicating that is displayed on the operation record data processing unit 12
Therefore, the operation record data processing unit 12 causes the operation record data storage memory 14 to move the start switch 11A
The operation record data for the switch, the numerical value, the character setting area, etc. in the fixed screen 11 which is performed after the button is pressed until the stop switch 11B is pressed is read.

The operation record data is sent to the PC 2 via the communication line 3 here. Then, the POD 1 can operate according to the operation record data as if the operations were performed in that order.
It enables continuous testing and demonstration of equipment.

Further, for example, the operation record data storage memory 1
Reference numeral 4 denotes a memory area in which data can be exchanged with a PC. Here, as described above, the operation target, operation content (switch pressed / released), operation time (relative time from recording start or It is possible to communicate the operation data between the POD 1 and the PC 2 by defining each data area (absolute time) and the like and using an appropriate protocol such as handshake. Communication of this operation data is POD1
Alternatively, it is performed by issuing a predetermined instruction on the PC 2.

Although the switches for starting, stopping and reproducing the operation recording are provided inside the fixed screen 11 in FIG. 1, they may be provided outside the fixed screen, for example, on the communication line 3. . By doing so, it is possible to use it, for example, in an environment where the fixed screen is unclean.

[0016]

According to the present invention, the following (1) to (3) are provided.
The following advantages can be obtained. (1) Since POD operation recording can be performed only by providing recording instruction means, it is possible to obtain important data for machine / equipment abnormality analysis without the need for a PC. (2) Since the recorded operation data can be reproduced without using a special program, an operator is not required during a temporary test operation. (3) Since the operation data can be transferred to the PC, the data can be sent to another POD via the PC, and the usability of the data can be improved. It can also be used for functional verification of POD itself, facilitating automation for development testing and reducing manpower.
