BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a supervisory control apparatus and a state change processing method of the supervisory control apparatus according to the present invention. As shown in FIG. 5, the monitoring control device
The apparatus includes at least a field device 1 and an apparatus main body 2, and the apparatus main body 2 further includes a central processing unit 2a, a memory 2b, and a display device 2c. This monitoring control device performs monitoring control using measurement data as in the prior art, but differs in the processing of the state change data output from the field device 1. Hereinafter, this point will be mainly described.

FIG. 1 shows the flow of the state change data of the present embodiment.
FIG. 9 is an explanatory diagram illustrating a process. When an abnormality occurs in the field device 1 or when the operation mode of the field device 1 is changed, the field device 1 outputs state change data as shown in FIG. It also outputs calendar data and device number data managed by the device 1. These data are stored in the central processing unit 2a.
Sent to The data is received by the control means of the central processing unit 2a, temporarily stored in an internal memory or the like, and then written as a deformed block data in a secondary file of a storage medium such as a hard disk. Each time a state change occurs, it is transferred from the internal memory to a secondary file, so even if the period from the occurrence of the state change to the end is short,
All changes are saved.

The details of the block data will be described with reference to FIG. 2A and 2B are schematic diagrams of the deformed block data. FIG. 2A is an overall structural diagram, FIG. 2B is a structural diagram of a date / time / device number data field, and FIG. Structure diagram of map data field, FIG.
(D) is a structural diagram of a state change ON / OFF bitmap data field.

The state change block data represents a block of data formed based on state change data, calendar data, and apparatus number data output from the field device 1 due to a state change as one block. 2
Date and time / device number data field as shown in (a),
The data area is divided into a word number data field, a shape change bit address map data field, and a shape change ON / OFF bit map data field.

FIG. 2 shows the date / time / device number data field.
As shown in the data structure shown in (b), year / month / day / hour / minute /
Calendar data that can be specified up to seconds, and device number data indicating any of the field devices 1 ₁ , 1 ₂ ,..., 1 _n are recorded. This calendar data is
Since the calendar data is generated by the field device 1 when an abnormality occurs in the field device 1, the calendar data represents the exact time of occurrence of the abnormality. In the present embodiment, since the calendar data transmitted from the field device 1 is stored, it is possible to know the exact time of occurrence of the abnormality.

The state change bit address map data field has a data structure as shown in FIG. 2C, and the state change ON / OFF bit map data field has the data structure shown in FIG.
Although the data structure is as shown in (d), how to use these data will be described later.

These deformed block data are stored in an HM described later.
The data is written to the I area, but if there is no free space in the HMI area, the data is queued in a two-dimensional file over a plurality of blocks. For example, FIFO (First-In First-Ou) is an example of a queuing technique.
According to t), the state-changed block data is accumulated while maintaining the write control order, and when writing is possible, the state-changed block data is read out from the two-dimensional file on a first-in first-out basis and is written to the HMI area. Will be done.

If the queuing is performed in this manner, the state change data is written in the HMI area without fail in the writing of the state change data and in the order of occurrence of the state change. In such a case, the situation in which the HMI means fails to read the state change data and overlooks the state change is avoided.

The control means refers to the block number data in the block number data field of the HMI area having the data structure as shown in FIG. If this block number data is "0" (that is, H
If the MI area is empty), the CPU reads out the blocks of the deformed block data queued in the above-described two-dimensional file or the maximum writable blocks in the HMI area, and writes them in the HMI area. In this case, the data is written from the oldest deformed block data according to the first-in first-out principle. Then, the control means writes the end code data to the end code data field at the final address, writes the block number data, which is the number of blocks written, to the block number field, and finally writes the end code relative address field to the end code relative address field. , The relative address data of the field in which the end code data is written. The processing up to this point is performed by the control means.

On the other hand, the HMI means refers to the number-of-blocks data in the number-of-blocks data field of the HMI area having the data structure shown in FIG. In this case, a state change message text is created. The state change message text is created by the following procedure. First, the calendar data in the date / time / device number data field of the deformed block data is converted to create calendar text data representing year, month, day, hour, minute, and second, and stored in the work memory X (not shown). Further, the device number data in the date / time / device number data field of the deformed block data is converted to create text data representing the field device number, and stored in the work memory Y (not shown).

Next, the status change item and the status of the status change are specified with reference to the status change bit address map data. The position of the state change bit address map data corresponds to the state change item. For example, in FIG. 2C, if the bit address 1 of the word address 0 is ON, the state change indicates that the state change item A has occurred, or the state change of the word address 0 has occurred.
If the bit address 2 is ON, the status change indicates that the status change item B has occurred.

Further, if the bit address 1 of the word address 0 is turned off, the status change indicates that the status change item A is completed, and if the bit address 2 of the word address 0 is turned off, the status change is performed. This indicates that the status change item B has been completed. The status change item and the status of the status change can be represented by such status change bit address map data. The number of state changes is 16 × N as shown in FIG.
A large number of data changes can be represented by a small number of data.

Next, reference to the state change bit address map data will be described with a specific example. For example,
It is checked whether the state change bit address map data of block 1 is ON or OFF in order from bit address 0 of word address 0. In this case, if it is confirmed to the bit address F of the word address 0, then the word address 1
Jumps to bit address 0 of, and performs the same processing thereafter.

A case where an ON bit is detected during the confirmation will be described. For concreteness of the description, the case where the bit address 2 of the word address 0 is ON is described with reference to FIG. 4A and 4B are explanatory diagrams for explaining a state change message text. FIG. 4A is an explanatory view of a state change message text table example of the field device number 1, and FIG. 4B is a view of a state change message screen display example. FIG. If ON is detected at bit address 2, first, a state change message text table with a matching device number is selected, and then a line corresponding to the bit address of the state change message text data table (that is, 2 if bit address 2). Line change message text data of line 2) is extracted [state change message text data A].

For example, if the device number of the block 1 is 1, a state change message text data table for the device number 1 as shown in FIG. 4A is selected. Means that "light fault occurrence recovery ALM" [state change message text data A] on the second line is selected.

The state change message text data is a combination of four types of state change item text data, ON state text data, OFF state text data, and state change type text data. "" Corresponds to state change item text data, "occurrence" corresponds to ON state text data, "recovery" corresponds to OFF state text data, and "ALM" corresponds to state change type text data.

Next, the HMI means turns on the state of block 1.
Although the / OFF map data is referred to, the bit data at the same position as the word address and the bit address which are ON in the state change bit address map data of the block 1 are referred to. In the above example, bit address 2 of word 0 is referred to.

Processing is different depending on whether the bit data is ON or OFF. First, the case of ON will be described. When the bit data is ON, the text data at the time of ON is adopted and displayed, and the text data at the time of OFF is not adopted. Subsequently, the status change type text data of the last three characters of [state change message text data A] (in this embodiment, ALM / MNT / ANN / STS / EVT)
According to the display color code text data (for example,
1, 2, 3, etc.) is added to the end of [state-change message text data A] [state-change message text data B]. Further, the text at the OFF data position is replaced with blank character data (so-called space) (for example, in the message text on the second line shown in FIG. 4A, the "recovery" character is replaced with a space) [state change message text data C ].

In the above example, the state change ON / OF
If the F data map data is OFF instead of ON, text data at OFF is displayed and displayed, and text data at ON is not used. Further, OFF display color code text data (0 in this embodiment) is added to the end of [state change message text data A] [state change message text data B]. Then, the ON-time text data is replaced with a blank character (for example, in the message text data on the second line shown in FIG. 4A, the "occurrence" character is replaced with a space) [state change message text data C]. In this embodiment, the display color code 0 is “green”, 1 is “red”, 2 is “orange”, and 3 is “yellow”.

Finally, the calendar text data stored in the work memory X and the device number text data stored in the work memory Y are connected to the head of [state change message text data C] to newly change the state. Generate message text. The state change message text generated in this manner is stored in the screen display text data file and the storage text data file. This operation is repeated for a plurality of blocks to generate a state change message text for all blocks.

Finally, the end code relative address data is cleared, that is, 0. In the state change message text screen display by the HMI means, the state change message text data or the background is color-changed and displayed according to the display color code with reference to the screen display text data file updated in the above processing. FIG. 4B shows a display example by the display device 2c. For example, the first and second lines from the top,
In the fifth and sixth lines from the top, either ON-state text data or OFF-state text data is adopted from the same state change message text data, and only one of the states is displayed. By doing this,
The data can be displayed in one table without changing the table in a predetermined format.

[0044]

As described above, according to the present invention, a field device obtains an accurate time of occurrence of an abnormality, and transmits state change data, device number data, and calendar data when a state change occurs. The control means queues the shape-changed block data generated from, and if there is a free space in the HMI area, the queued shape-changed block data is written to the HMI area on a first-in first-out basis. Further, the HMI means sequentially takes out the state-changed block data from the HMI area and generates and displays the state-change message text data in the order of occurrence of the abnormality. With such a configuration, it is possible to obtain an accurate time of occurrence of an abnormality in a field device, display the state change message text on a display device accurately in the order of detection of the field device, and realize the accuracy of the abnormality analysis. Can be.

Since the HMI state change message text data includes a plurality of text data, and the state change ON message and the state change message are described on the same line, the state change message displayed on the HMI screen is displayed. There is an effect that the display content can be easily changed according to the end user's preference. Further, even when a field device is added, it is easy to change the state change bit address map data and the state change ON / OFF bit map data and to add the state change message data. Easy to change. In this way, the status change message text data can be easily changed so that the status change message is tailored to the actual usage of the user, and the abnormal status is speedily analyzed by expressing the status change immediately. can do.

In general, accurate time / abnormal contents can be displayed, and accurate and quick abnormality analysis can be realized.
