Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control and monitoring device which includes a display device such as a CRT display device and an input device such as a keyboard for inputting numerical values, and which controls and monitors a controlled object such as a plant.

[0002]

2. Description of the Related Art Conventionally, in a control / monitoring device which is provided with a display device such as a CRT display device and an input device such as a keyboard for inputting numerical values, and which controls and monitors a controlled object such as a plant, the display device has parameters. Is displayed and the parameter is changed by an operation from the input device, the following two methods are generally taken as a countermeasure against erroneous input. One is a method that does not allow erroneous input, and a method that confirms whether or not the change data is correct before actually changing the parameter. The other one is that the change operation can be canceled after erroneous input. It is a system that allows it.

In the latter method of canceling the erroneous input later, conventionally, the data before the change is stored in the process of the parameter display change screen, and when the cancel request is input, the numerical value before the change is set. A method of returning the value or a method of returning the value to the original value by an operator's manual operation is adopted.

[0004]

However, in the method of canceling an erroneous input afterwards, the data before the change is stored in the process of the parameter display change screen, and if the cancel request is input, the change before the change is performed. In the method of returning to the numerical value, the process of storing the previous operation and the display for requesting cancellation of the previous operation,
It is necessary to insert the operation into each screen, and there is a problem that the screen creation work becomes complicated. In addition, because the previous operation was canceled, if another operation is entered or another screen is displayed during the operation, the change operation will be fixed and it will not be possible to cancel it, which is inconvenient. It was

In the method of canceling an erroneous input later, in the method in which the operator manually operates, the operator sees the change record and re-changes it to the value before the operation, but it is printed for that purpose. It is necessary to look at the result, which is troublesome, and there is a problem in that it may not be possible to accurately return to the original value due to the number of print digits.

The present invention has been made in view of the above-mentioned conventional problems, and provides a control monitoring apparatus capable of easily canceling a parameter change without adding special processing to a screen for changing a parameter. The purpose is to do.

[0007]

The present invention comprises an input operation section, a display section, a parameter data storage section, and a change operation message storage section for sequentially storing parameter data change operation messages. In the control and monitoring device that sequentially stores the newly changed parameter data in the parameter data storage unit by changing the displayed parameter data by an operation from the input operation unit, A change operation message display processing unit that displays a list of change operation messages that are displayed on the display unit, and a list of change operation messages that are displayed on the display unit by the change operation message display processing unit with respect to specific parameters. Cancel the change operation and return to the parameter data before the change Cancel the change It is obtained by a processing section.

[0008]

In the control / monitoring apparatus of the present invention, the function of storing and displaying the record of the change operation, which has been conventionally provided, is used, and the parameter stored in the change operation message storage section is set by the change operation message display processing section. By displaying the list of change operation messages in the display section and selecting the parameter that needs to be changed from this change operation message list using the input operation section, the detailed content of the selected change operation message is displayed. When the change operation message is displayed on the display section by the processing section and the change operation is instructed by the input operation section, the change operation message selected by the change cancellation processing section is canceled and the parameter data before the change is restored. Let

In this way, when it is desired to restore the original data after performing the parameter data changing operation, it is always necessary to cancel the changing operation by referring to the stored data in the changing operation message storage section and restore the original data. You can

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows a functional block diagram of an embodiment of the present invention, and FIG. 2 shows a hardware configuration.

First, the hardware configuration of the control and monitoring apparatus of this embodiment will be described. As shown in FIG.
A display device 1 including a T display device, a keyboard for performing an input operation, an input device 2 such as a mouse installed as necessary, and a control and monitoring processing device 3 which is a main body of the control and monitoring device and includes a computer. , An external storage device 4 such as a hard disk for storing various parameter data, change data, and other data.

The parameter change cancel function of the control and monitoring apparatus of this embodiment is incorporated into the computer of the control and monitoring processing apparatus 3 as one software program and executed, and its configuration is shown in FIG. Explaining based on a functional block diagram, the parameter data table 5 storing various parameter data necessary for the plant to be controlled and monitored, and the parameter data displayed on the display device 1 are changed by an input operation by the input device 2. A parameter change processing unit 6 that performs the parameter change process at that time, a change operation message storage table 7 that stores the data before and after the change of the parameters changed by the parameter change processing unit 6 in a format described later, Save various input operations by the input device 2 one by one Ku message memory 8, a message storage processing unit 9 for processing stored and saved for this message memory 8. The parameter data table 5 for storing various data, the change operation message storage table 7, and the message storage unit 8 are stored in the external storage device 4 in separate storage areas.

The control and monitoring apparatus of this embodiment also has, as a main component, a stored message display processing section for performing processing for displaying a list of input operation messages stored in the message storage section 8 on the display apparatus 1. 10. Processing for calling up a list of parameter change operation messages from the change operation message storage table 7 and enumerating them on the display device 1 when a cancel request is input from the list of input operation messages displayed on the display device 1 The change operation message selection display processing unit 11 for performing the change operation and the change cancel processing unit 12 for canceling the parameter change and returning to the original data when the change operation message displayed on the display device 1 is cancelled. Is equipped with.

Next, the operation of the control / monitoring device having the above-mentioned configuration will be described.

The parameter data table 5 of the external storage device 4 initially has the set values incorporated therein. However, when it is necessary to change the set values, a parameter change command is input from the input device 2 to perform a parameter change process. Part 6
Causes the display device 1 to display the parameter change screen 13 as shown in FIG. Therefore, by specifying the type of parameter that needs to be changed and further specifying the parameter number, the corresponding parameter is called from the parameter data table 5, and new parameter data can be set using the input device 2.

By this series of parameter changing operations, the changed parameter data is set in the parameter data table 5 as shown in FIG. 3 (arrow a), and the changing operation message is registered in the changing operation message storage table 7 ( Arrow b). The format of this change operation message is as shown in FIG. 5, and the change time f1
Message type (here, “parameter change”) f2, parameter type f3, parameter number f4,
Parameter value f5 after change, parameter value f6 before change
From this, data 7a for one message is constructed.

In the message storage unit 8, all of the input operations from the input device 2 are stored by the message storage processing unit 9, and the messages for the above-mentioned parameter changing operations are sequentially stored and other operation messages are stored. The record of will be registered.

When some of the parameters have been changed by the above changing operation and the parameters have already been registered in the parameter data table 5, if one of the parameters needs to be returned to the original value, the following operation is performed. To cancel the parameter change.

As shown in the flow chart of FIG. 6, first, a message recording display screen previously incorporated by an input from the input device 2 is called up on the display device 1,
When a command for displaying a list of stored messages is input from the input device 2, the stored message display processing unit 10 refers to the message storage unit 8 to create a list of input operation messages and displays the list on the display device 1 (step S1). , S
2). In the list display of the stored messages, not only the parameter change operation message but also various input operation messages performed by the operator through the input device 2 are listed and displayed in a list format.

Therefore, by inputting a parameter change operation cancel request by operating each function key from the input device 2 or by selecting a soft key displayed on the display screen of the display device 2 (step S3), the change operation is performed. The message selection display processing unit 11 refers to the change operation message storage table 7 as shown by the arrow c in FIG. 3, and shows a list of only change operation messages that have been executed and registered as shown in FIG. It is displayed in the format on the screen 14 with the parameter change cancel function (step S4).

Therefore, if the parameter type or parameter number for which the parameter change is desired to be canceled is selected from the input device 2 (step S5), the specified parameter type and number are read from the change operation message storage table 7 (step S6). The parameter values of the read parameter type and number are returned to the values before the change, and the restored parameter values are registered again in the parameter data table 5 as indicated by the arrow d in FIG. 3 (step S
7).

Thus, with respect to the parameter data returned to the original, the cancel operation is recorded as a change operation message in the change operation message storage table 7 as a new change operation as shown by an arrow e in FIG. The record is also stored in the message storage unit 8 and the screen returns to the record display screen (step S8).

The change canceling process is repeatedly executed for the parameters that need to be canceled in the above procedure, but if there are no parameters to cancel the change, step S
It is possible to return to the original record display screen by canceling cancellation without designating the cancellation item in step 5 (step S9).

In this way, the once-determined parameter changing operation can be canceled at any time, and the degree of freedom of the parameter setting operation is greatly improved.

In the above embodiment, the external storage device 4 including the parameter data table 5, the change operation storage table 7, and the message storage unit 8 is attached to this control and monitoring device, but is connected by a network such as a LAN. It is also possible to use a storage device existing in another station, and there is no particular limitation.

In the above embodiment, in order to cancel the parameter changing operation, the record display screen is called, and the parameter changing cancel request is input to call the list of parameters which have been changed from the changing operation message storage table. Although it is displayed on the screen with the parameter change cancel function, it is possible to incorporate the change cancel processing function into the normal parameter change screen.
By inputting the cancel request, only the parameters that can be changed and canceled can be called from the change operation message storage table and displayed, and the parameter to be canceled can be easily specified.

[0028]

As described above, according to the present invention, the list of the parameter change operation messages stored in the change operation message storage section is called up on the display section and displayed in an enumerated manner, and the selection is given to cancel input. By doing so, the change parameter is canceled and the value before the change is returned to the original value.Therefore, like the conventional method to correct the erroneous input when changing the parameter data, the change operation can be changed to other operation. After changing to, you can always cancel the data change, you can always call the change operation message from the change operation message storage section and return it to the value before the change operation, and you can easily perform the change cancel operation. .
