  However, in the above conventional configuration, a history table such as an alarm is displayed by the above screen design, and the contents of the history table are output as CSV (Comma Separated Values) data, or as print data for instructing the printer to print. To output the contents of the history table, such as outputting the contents of the history table, for example, if an object for data output is provided separately from the display and the contents of the history table are output, the same as the object for display It is necessary to set this, and it takes time and effort.

  If the data of the history table is collected in a specific storage area and all the history tables have the same data structure / the same amount of data, it is only necessary to set the area. In this case, if the user, the application, or the device or the PLC model is different, the data structure / data amount is also different, and the storage area may even be distributed.

  Therefore, in order to display properly, it is necessary to set a display data format such as a character string, a Dec value, or a Hex value, or a storage area for each display object. As described above, even if the time for designing the screen is reduced, the setting of each display object still takes time. As a result, if an object for data output is provided and an attempt is made to set the display object in the same manner as that for setting the display object, the effort is not negligible.

  Note that the problem of time and effort during setting is not limited to the history table, and generally occurs when data is output in a display data format similar to that at the time of display. In addition to managing components as objects, device information, position information, and display data format information are stored in association with each other, communicated with a control device that controls a device specified by the device information, and The device value is acquired, and the acquired value in the format indicated by the display data format information stored in association with the device information is displayed at the position indicated by the location information stored in association with the device information on the screen. It also occurs when displaying.

  The present invention has been made in view of the above problems, and an object of the present invention is to realize a display device that can output a desired device value in a desired data format with relatively little effort. is there.

  In order to solve the above problems, a display device according to the present invention includes a storage unit that stores device information, position information, and display data format information in association with each other, and a device specified by the device information as display processing. Display data format stored in association with the device information at the position indicated by the position information stored in association with the device information on the screen while acquiring the value of the device by communicating with the control device to be controlled A display device that performs processing for displaying the acquired value in a format indicated by the information, and the storage device stores range information and when data output is instructed, As a data output process, it is indicated that a value is displayed within the range indicated by the range information on the screen from the position information stored in the storage means. When the position information is found, the position information is communicated with the control device to acquire the value of the device specified by the device information stored in association with the position information, and the position information And a data output means for performing a process of outputting the acquired value in the format indicated by the display data format information stored in association with.

  The display means is generated for each combination of device information, position information, and display data format information stored in association with each other in the following objects, and each combination is set as an attribute value. It may be realized as a set of objects. The data output means may also be realized as an object in which range information is set as an attribute value.

  In the above configuration, for example, when data output is instructed, such as a print instruction or an output instruction to a recording medium, the position information stored in the storage unit is within the range indicated by the range information. Location information indicating that a value is to be displayed is retrieved. When the position information is found, the device value indicated by the device information stored in association with the position information is acquired by the data output means, and the acquired value is the display data stored in association with the position information. Data is output in the format indicated by the format information.

  In this configuration, the data output means refers to the device information and display data format information stored for display processing, acquires the device value indicated by the device information, and in the format indicated by the display data format information. Output the acquired value as data. Therefore, compared with the configuration for setting these pieces of information for data output, it is possible to greatly reduce the time and effort at the time of setting.

  The data output means searches for position information indicating that a value is to be displayed within the range indicated by the range information, and performs the data output processing for the found position information. Therefore, the range information is set to an appropriate value, for example, the position indicated by the position information of a desired combination among the combinations of device information, position information, and display data format information, such that the range includes the range information. Unlike the configuration for capturing a screen, only desired values can be output as data.

  As a result, it is possible to realize a display device that can output a desired device value in a desired data format with relatively little effort.

  In addition to the above configuration, the storage means can also store character strings and position information associated with each other, and the display means stores position information associated with the character strings in the storage means. In this case, the character string is displayed at the position indicated by the position information associated with the character string on the screen, and the data output means stores data in the storage means as a data output process when data output is instructed. From the stored position information, the position information indicating that the character string is displayed within the range indicated by the range information is searched for on the screen, and if the position information is found, the position information A process of outputting data of a character string stored in association may be performed. In this case, in addition to the objects described above, the display means is generated for each combination of the following objects, that is, character strings and position information stored in association with each other in the storage means. It may be realized as a set of objects set as values.

  In this configuration, if the display means displays a character string, the range information is set to include the position indicated by the position information associated with the character string, and the character string is also output as data. be able to.

  Here, in many cases, when displaying a list of data, a character string such as an item name is also displayed. When outputting data, it is desirable to output the character string as well. Therefore, by setting the above range information as described above, the character string is also output as data, and the desired device value is output in the desired data format together with the character string with relatively little effort. Possible display devices can be realized.

  Further, in addition to the above configuration, the display means can switch and display a plurality of screens, and the storage means also stores screen information indicating the screen in association with each position information and range information. In the range information, if there is a screen to which data is to be output next, the next screen information indicating the screen is stored in association with the screen, and the display means displays the screen indicated by the screen information as follows: When the display processing for the position information indicating a screen other than the currently displayed screen is stopped, and the data output means performs the data processing for the range information stored in association with the screen information indicating a certain screen, The screen indicated by the screen information cancels the data output processing for the position information indicating a screen other than the screen currently outputting data, and the screen indicated by the screen information When the data output process is completed for all the position information indicating the screen being output, the data output process may be performed for the range information associated with the screen indicated by the next screen information associated with the range information. Good.

  In the configuration, when the data output process is completed for all the position information indicating the screen that is currently outputting data, the data for the range information associated with the screen indicated by the next screen information associated with the range information is displayed. Since the output process is performed, the data to be displayed over a plurality of screens can be collectively output.

  On the other hand, a drawing device according to the present invention is a drawing device that generates information stored in any of the storage means of the display device in order to solve the above problems, and includes device information, position information, and display data format. Drawing device storage means for storing information in association with each other, and display means for displaying a graphic corresponding to the device information, position information and display data format information associated with each other at a position indicated by the position information on the screen And editing means for editing the information stored in the drawing device storage means in response to a user operation, and the editing means receives the range information addition operation and receives the range information as the drawing device. In addition to storing in the storage means, the display means also draws the range indicated by the range information on the screen on which the graphic is drawn.

  The drawing device according to the present invention is a drawing device that generates information stored in a storage unit of a display device capable of displaying the plurality of screens in order to solve the above-described problem, and includes device information and position information. The drawing device storage means for storing the display data format information and the screen information in association with each other, and the currently displayed screen among the combinations of the device information, the position information, the display data format information and the screen information associated with each other. A drawing device display means for displaying a graphic corresponding to the combination associated with the screen information to be displayed at the position indicated by the position information, and editing the information stored in the drawing device storage means in response to a user operation. And editing means that receives the range information addition operation, the editing means associates the range information with screen information indicating the currently displayed screen. Therefore, the drawing device storage means stores the drawing device display means on the screen on which the figure is drawn, and also draws the range indicated by the range information. When the next screen information indicating the next screen is instructed, the next screen information is stored in association with the range information.

  In these drawing devices, upon receiving the range information adding operation, the drawing device storage unit adds the range information, and the drawing device display unit displays the range information on the screen on which the graphic is drawn. The range shown is also drawn. Therefore, each information for the display device described above can be generated while comparing the position indicated by the position information and the range indicated by the range information, which is presented by the position of the graphic corresponding to the combination.

  Further, as described above, the data output means of the display device refers to the device information and display data format information stored for display processing, and displays values within the range indicated by the range information. The position information indicating is searched.

  As a result, information for operating a display device capable of outputting a desired device value in a desired data format can be generated with relatively little effort.

  In addition to the above configuration, when the editing unit accepts a movement or size changing operation of the range indicated by the range information, the editing unit changes the range information stored in the drawing device storage unit in accordance with the operation. When the range information stored in the drawing device storage unit is updated, the drawing device display unit may update the drawing of the range on the screen in accordance with the updated range information.

  In this configuration, the editing unit accepts the movement or size change operation of the range indicated by the range information, and the drawing device display unit updates the drawing of the range on the screen accordingly. Therefore, it becomes easy to update the range information in accordance with the device information and display data format information already generated for the display process, and it is possible to reduce time and labor when setting the range information.

  Further, in addition to the above configuration, the range information indicates a range partitioned in a lattice shape, and the editing means moves to at least one of a frame line of each lattice and an outer frame of the lattice. The range information may be updated according to the operation.

  In this configuration, the range is divided in a lattice shape, and the range information is updated in accordance with the movement operation to at least one of the frame line of each lattice and the outer frame of the lattice. In this configuration, if the device values or character strings are arranged in a matrix, the outer frame of the lattice is arranged so as to include them, and the frame of each lattice is moved so that each lattice includes each of them. Then, the device values or character strings arranged in a matrix can be output as data. As a result, it is possible to reduce time and labor when setting the range information.

  By the way, the display device and the drawing device may be realized by hardware, or may be realized by causing a computer to execute a program. Specifically, the program according to the present invention is a program that causes a computer to operate as any of the means of the display device or as any of the means of the drawing device, and is stored in the recording medium according to the invention. The program is recorded.

  For example, when the computer reads the recording medium and the programs are executed by the computer, the computer operates as the display device or the drawing device. Therefore, similarly to the display device and the drawing device, a desired device value can be output in a desired data format with relatively little effort.

  The display device according to the present invention refers to the device information and display data format information stored for display processing, acquires the device value indicated by the device information, and acquires the value in the format indicated by the display data format information. Since the output value is output as data, the setting time can be greatly reduced. Further, since the position information indicating that the value is displayed within the range indicated by the range information is searched and the data output process is performed on the found position information, only a desired value can be output as data. As a result, it is possible to realize a display device that can output a desired device value in a desired data format with relatively little effort.

  On the other hand, the drawing device according to the present invention adds range information upon accepting the range information addition operation, and also draws the range indicated by the range information on the screen on which the graphic is drawn. Therefore, each information for the display device described above can be generated while comparing the position indicated by the position information and the range indicated by the range information, which is presented by the position of the graphic corresponding to the combination. Further, as described above, the display device refers to device information and display data format information stored for display processing, and indicates that a value is displayed within the range indicated by the range information. Searching for location information. As a result, information for operating a display device capable of outputting a desired device value in a desired data format can be generated with relatively little effort.

  An embodiment of the present invention will be described below with reference to FIGS. That is, the control system according to the present embodiment is suitably used for controlling a target system provided in a manufacturing plant, for example, and includes, for example, a belt conveyor type automatic assembling machine. It is used to control the device (control target).

  Below, before describing the configuration for the graphic operation panel functioning as the HMI of the control system to output data such as CSV output and printing, the schematic configuration and operation of the entire control system will be described. That is, as shown in FIG. 2, in the control system 1, a plurality of control units 11 are connected to each other via a local area network (LAN) 12. Each control unit 11 is connected to the PLC 13 as a control device that controls the device 3 of the target system 2 and a PLC 13 via a communication path such as a serial cable, and as an HMI of the control system 1. A graphic operation panel (touch panel device) 14 that displays the state of the device 3 and receives an operation on the device 3 by an operator is provided. Furthermore, in the control system 1 according to the present embodiment, a control host computer 15 that manages the entire control system 1 is connected to the LAN 12 from a location far from the graphic operation panel 14 in many cases.

  In FIG. 2, for convenience of explanation, two control units 11 are connected to the LAN 12, two PLCs 13 are provided on one side of the graphic operation panel 14 of each control unit 11, and three PLCs 13 are provided on the other side. Although the case where one device 3 is connected to each PLC 13 is illustrated as an example, the number of connected devices can be arbitrarily set as a matter of course. The device may be any device as long as it can be specified by the device address and can acquire or control (change) the state. For example, it may be the device 3 itself, for example, the PLC 13 or the graphic operation panel. An area of a storage device provided in the control system 1 such as 14 storage devices may be shown.

  Furthermore, in the control system 1 according to the present embodiment, when the control units 11 are connected, the graphic operation panels 14 are connected via a LAN 12 such as Ethernet (registered trademark).

  As described above, the control system 1 according to the present embodiment is a configuration essential to the control system 1 and operates as an HMI, so that the graphic operation panel 14 having sufficient computing power processes most of the communication. It is configured. Furthermore, each graphic operation panel 14 converts a dedicated protocol specific to the model of the PLC 13 connected to itself and a common protocol in the LAN 12, and other graphic operation panels 14 and other devices in the LAN 12, Relay communication with the PLC 13. For protocol conversion between the common protocol and the dedicated protocol, conversion between a predetermined common command so that the same code is assigned to the same instruction and a command unique to the PLC 13 corresponding to the common command is performed. And conversion of data and address expression methods.

  As a result, devices (such as the graphic operation panel 14) in the LAN 12 can communicate with each other using the common protocol via the LAN 12, regardless of the model of the PLC 13 connected to the other graphic operation panel 14. As a result, the control system 1 in which different types of PLCs 13 are mixed can be realized relatively easily.

  More specifically, the graphic operation panel 14 is a display device that performs an input receiving operation and a screen display operation based on screen data that defines a display / control operation, and includes, for example, a liquid crystal display panel. 3, a touch panel 22 arranged on the display screen of the display 21 for receiving operations from an operator, and a PLC / interface unit (PLC / IF unit) for connecting to the PLC 13. 23, the LAN / IF unit 24 for connecting to the LAN 12, the storage unit 25 in which the screen data is stored in advance and the state of the device 3 and the like are stored, and the screen data in the storage unit 25 is referred to. However, the HMI process part 26 which controls the said members 21-24 is provided.

  In addition, each said members 23-26 and each below-mentioned 61-63 and 71-74 perform the program stored in memory | storage means, such as ROM and RAM, by arithmetic means, such as CPU, and the display 21 or touch panel 22 is a functional block realized by controlling input / output means such as 22, or a communication circuit such as an interface circuit. Of these members, each of the storage units 25, 62, and 71 may be a storage device such as a ROM or a RAM.

  Therefore, the computer having these means reads the recording medium (for example, CD-ROM) on which the above-mentioned program is recorded and executes the program. The drawing editor device 16 can be realized. For example, if a program for downloading a program via the LAN 12 or another communication path is installed in the computer in advance, the program is distributed to the computer via the communication path. You can also.

  The screen data according to the present embodiment is data for generating an object on the graphic operation panel 14, and the HMI processing unit 26 of the graphic operation panel 14 has a parameter (attribute value) indicated by the screen data. Moreover, it is possible to generate an object of the type indicated by the screen data.

  Here, the objects that can be generated by the HMI processing unit 26 according to the instruction of the screen data are not only objects that display predetermined information such as character strings or images, but can be operated by acquiring the state of the device 3, for example. Also included are component objects (not shown) that perform various operations such as an operation to be displayed on the screen and an operation to accept an operation on the operation screen and instruct to change the state of the device 3.

  When the component object is generated by the HMI processing unit 26, the above-described various operations are performed to display the state of the device 3 on the operation screen or to instruct a change in the state of the device 3 according to the operation on the operation screen. Thereby, the graphic operation panel 14 can display the state of each device 3 indicated by the screen data on the operation screen, and can accept the state change operation of the device 3.

  More specifically, the display component object according to the present embodiment specifies the device status display method (display data format) by its type and the value of the display data format attribute AF. For example, there are provided a device that displays a device state by a numerical value, a device that displays a device state by a graphic shape, and a device that displays a device state by a graph.

  Here, the memory 13a of the PLC 13 can store data in various display data formats, and the display data format of each data can be set to a value according to the purpose of each data. For example, in the case of a numerical value, the display data format is, for example, data that should be expressed as Dec, data that should be expressed as Hex, data that should be expressed as BCD, or should be expressed as Oct. Data, which data should be represented by any representation method, whether or not there is a sign, a data length, or a combination thereof. In the case of a character string, examples of the display data format include character length, terminal character, character code, and line feed code. If the PLC 13 model or the control program stored in the PLC 13 is changed, a different display data format is used for the same application (for example, data indicating the state of a certain device 3). May be stored.

  On the other hand, among the display component objects according to the present embodiment, as shown in FIGS. 3 and 4, the data stored in the PLC 13 is data in any display data format. Even so, the display data format attribute (display data format attribute) AF is attached so that the data can be displayed correctly, and the display component object displays the display data indicated by the display data format attribute AF. The value to be displayed can be specified by judging the format.

  In the present embodiment, as an example, a numerical display data format is specified by a combination of which data should be expressed, whether there is a sign, and the data length. Then, a certain object is set to process the data “D01000” as data to be expressed in Dec expression of 16 bits in length with no sign.

  In addition, in the case of the display object that acquires and displays the state of the device 3 among the component objects, as shown in FIGS. 3 and 4, a device for specifying the device 3 whose state is to be acquired. The attribute AD is attached, and the display component object instructs the PLC / IF unit 23 to acquire the state of the device 3, for example, or the PLC / IF unit 23 acquires it at a predetermined timing. The state of the device 3 can be acquired by referring to the state of the device 3. In the present embodiment, as the device attribute AD, for example, as shown in FIG. 4, a value indicating the address in the memory 13a of the PLC 13 (“D01000” in the example of FIG. 4) is set.

  Further, as shown in FIG. 3, the display component object is also provided with a position attribute AL indicating the position of the area for displaying the state of the device 3, and the display component object is displayed on the operation screen at the position. The state of the acquired device 3 can be displayed in the area indicated by the attribute AL. The position attribute AL may be any value as long as the area occupied by each object can be specified, but in this embodiment, a combination of the upper left XY coordinate and the lower right XY coordinate is used as the position attribute AL. Yes.

  Here, when the display component object is generated in the HMI processing unit 26 and, for example, it is determined that the display timing of the state of the device 3 is reached by an instruction from the HMI processing unit 26 or its own determination, the display component object is displayed. Acquires the state of the device 3 indicated by the device attribute AD as described above. Further, the display component object displays the value as indicated by the display data format attribute AF in the area indicated by the position attribute AL in the operation screen. Thereby, the state of the device 3 is numerically displayed on the operation screen.

  In addition, the character string object that displays a preset character string includes a content attribute indicating the content of the character string in addition to the position attribute AL similar to that of the display component object. When the character string object is generated in the HMI processing unit 26, the character string object displays the character string indicated by the content attribute at the position indicated by the position attribute AL. Thereby, for example, a preset character string such as a nameplate can be displayed on the operation screen.

  Similarly, when the object is an input object that accepts an operation, the input object includes a device attribute AD indicating a device whose state should be changed when the operation is accepted, and an area that accepts an operation to the device 3. A position attribute AL indicating the position is attached. On the other hand, when the input object detects operation acceptance to the area by monitoring the presence or absence of an operation on the area indicated by the position attribute AL, for example, the input object controls the PLC / IF unit 23 to control the device 3 The state of the device 3 can be changed according to the received operation, for example, by sending a state change instruction to the PLC 13. An area corresponding to each device 3 is provided in a memory (not shown) of the graphic operation panel 14, and the PLC / IF unit 23 changes the contents of the area of the memory at a predetermined timing, respectively. When the PLC 13 is instructed to write back to the device 3 corresponding to the above, the input object rewrites the contents of the area corresponding to the device attribute AD and causes the PLC 13 to transmit a state change instruction to the device 13. Also good. The input object is also provided with a display data format attribute AF for converting a value designated by the operation into a value to be stored in the memory 13a of the PLC 13.

  When the input object is generated in the HMI processing unit 26 and operation acceptance to the area is detected, the input object, as described above, displays the value indicated by the operation in the format indicated by the display data format attribute AF. The value to be stored in the memory 13a of the PLC 13 is determined. Further, the input object changes the state of the device 3 indicated by the device attribute AD to the value. Thereby, the state of the device 3 is changed according to the operation on the operation screen.

  Thereby, the graphic operation panel 14 can display the state of each device 3 indicated by the screen data on the operation screen, and can accept the state change operation of the device 3.

  In the present embodiment, the screen data can include a plurality of screens, and a screen attribute indicating the screen is added to each object. On the other hand, the graphic operation panel 14 generates, for example, only an object whose screen attribute value indicates the currently displayed screen, or among the already generated objects, the currently displayed screen is set as the screen attribute value. It is possible to instruct only the object to display the screen and to notify only the object whose screen attribute value is the currently displayed screen to the operation on the screen.

  By the way, in the control system 1 according to the present embodiment, the screen data stored in advance is modified or newly created according to the user's operation, the display screen is designed, and new screen data is generated. A possible drawing editor device 16 is provided. For example, a device that can always communicate with the graphic operation panel 14 such as the control host computer 15 has the function of a drawing editor device. For example, the screen data is downloaded to the graphic operation panel 14 via the LAN 12 or the like. However, in the control system 1 according to the present embodiment, a drawing editor device 16 is separately provided as shown in FIG. When storing screen data in the graphic operation panel 14, for example, the screen editor device 16 is temporarily connected to the graphic operation panel 14 to transfer screen data, or screen data generated by the screen editor device 16 is transferred. The screen data can be stored in the graphic operation panel 14 by being stored in a recording medium (for example, compact flash (registered trademark)) and causing the graphic operation panel 14 to read the contents of the recording medium.

  More specifically, as shown in FIG. 5, the drawing editor device 16 modifies or newly creates screen data stored in advance according to the user's operation, designs a display screen, and creates a new one. A drawing processing unit 61 for generating simple screen data, and a storage unit 62 for storing the screen data generated by the drawing processing unit 61. Further, as an example, the drawing editor device 16 illustrated in FIG. 5 is configured to transmit screen data by communicating with the graphic operation panel 14, and to communicate screen data stored in the storage unit 62 to the graphic operation panel 14. A processing unit 63 is provided. When screen data is stored via a recording medium, a recording device for writing the screen data stored in the storage unit 62 on the recording medium may be provided instead of / in addition to the communication processing unit 63.

  The drawing processing unit 61 includes a working storage unit 71 in which information corresponding to screen data is temporarily stored, an editing processing unit 72 that receives a user instruction and rewrites the contents of the storage unit 71, and an editing unit The display processing unit 73 that displays the contents of the storage unit 71 edited by the processing unit 72 on the display 21 shown in FIG. 2 and the screen data stored in the storage unit 62 are expanded in the storage unit 71 or after editing. And a data input / output processing unit 74 for writing screen data corresponding to the contents of the storage unit 71 to the storage unit 62.

  Here, as described above, the screen data is configured by combining an object indicating a correspondence relationship between an area on the screen and an address that can identify a device corresponding to display or input in the area. The editing processing unit 72 of the drawing processing unit 61 displays, for example, a palette of classes serving as object templates, and prompts the user to select a class in the palette and place a desired object on the screen. Further, upon receiving an object placement operation by the user, the edit processing unit 72 changes the contents of the storage unit 71 so that the screen data being edited includes the data of the placed object according to the operation. The display processing unit 73 displays the object at the designated coordinates based on the contents of the storage unit 71. Further, the edit processing unit 72 changes the contents of the storage unit 71 in accordance with a user operation such as drag and drop to adjust the value of the position attribute AL of the object, and the display processing unit 73 Display an object at a position. The edit processing unit 72 prompts the user to input an address related to the object, and the contents of the storage unit 71 (more specifically, the device device of the object so that the input address is related to the object). Attribute AD value) is changed.

  Similarly, as shown in FIG. 4, for example, the edit processing unit 72 displays a screen for displaying the attribute of the object, and displays each attribute value currently set for the object. When an instruction to change the attribute value of an attribute among the attributes of the object is received, the contents of the storage unit 71 are updated so that the attribute value of the specified attribute among the attributes of the object becomes the specified value. To do.

  The graphic operation panel 14 according to the present embodiment can switch and display a plurality of screens (operation screens), and the edit processing unit 72 performs an operation screen addition operation and an editing operation for each operation screen. In addition to accepting, the data of each object arranged on the operation screen can be stored in the storage unit 71 in association with each operation screen.

  On the other hand, when receiving the editing end instruction, the data input / output processing unit 74 generates screen data corresponding to the contents of the storage unit 71 and writes the screen data in the storage unit 62. Thereby, the screen data including the data for generating the edited object on the graphic operation panel 14 can be generated.

  As a result, the designer can create screen data simply by operating the drawing editor device 16 to place objects at desired positions on the screen and associating each object with the device address. Therefore, the display and operation of each graphic operation panel 14 can be determined (changed) more easily than when the display program of the graphic operation panel 14 is modified, and the user of the control system 1 (the designer who operates the drawing editor device 16). ) Can be adapted to the actual situation of the target system 2, the level of proficiency of the operator of the graphic operation panel 14, or the user's preference and judgment criteria.

  Here, the case where the current state of the device 3 connected to the PLC 13 is displayed or operated has been described as an example. However, as described above, the device may be the memory 13a of the PLC 13. For example, when a predetermined event (for example, an alarm) occurs, data indicating the event (in this case, alarm data) is sequentially stored in a predetermined area of the PLC 13 in a predetermined format. In addition, the data of the area is also displayed.

  As an example, the case of displaying an alarm history will be described. For example, the PLC 13 operates as a ladder program or the like according to a part of a control program written by the user of the PLC 13 or according to a program predetermined at the time of manufacture. It is operated to monitor whether or not an alarm is generated. When an alarm is detected, data indicating the alarm (alarm data) is generated and stored in the alarm storage area of the memory 13a.

  The format of alarm data according to the present embodiment is determined as shown in FIG. 6, for example. Specifically, each of the alarm data is 20-word data, and data indicating the time when the alarm is generated is stored in the first three words of each alarm data.

  In the first word (16 bits) of the three words, data indicating the year (Western calendar) is stored in the BCD format. Of the three words, data indicating the month and day are stored in the BCD format in the next one word and the next one word, respectively.

  In the next five words after the above three words, data indicating the type of the device 3 in which the alarm has occurred is stored as a data string of the ASCII code. In the 11th word (for example, “D01010”) counted from the top, data indicating the employee code of the operator who controlled the device 3 at the time of the alarm is 16 bits, unsigned and It is stored as Dec data. In addition, although the other data are also stored in the said alarm data, those description is abbreviate | omitted.

  On the other hand, the PLC 13 generates the alarm data in the above format every time the occurrence of an alarm is detected, and newly generates the alarm data in the area next to the area storing the latest alarm data in the alarm storage area. Stored alarm data. As a result, as shown in FIG. 7, alarm data is accumulated in the alarm storage area.

  The graphic operation panel 14 stores screen data for arranging objects as shown in FIG. 8 in order to display the alarm data accumulated in the alarm storage area.

  Specifically, as shown in FIG. 8, the objects for displaying the alarm data history are arranged in a matrix on the alarm data history display screen (history screen). FIG. 8 shows, as an example, a case where one record (one alarm) is displayed on one line, and display component objects O1a... Indicating the first alarm data are arranged on one line, and the second time on the next line. Display component objects O2a... Indicating the alarm data are arranged.

  Among the display component objects O1a... For displaying the first alarm, the display component objects O1a to O1c are display component objects for numerical display, and display the date when the alarm occurred. Is used. The device attribute AD of these display component objects O1a to O1c is an address of an area for storing data indicating the date of the alarm among the areas for storing alarm data (in the above example, “D01000”, “D01001”). "," D01002 "). The display data format attribute AF of the display component objects O1a to O1c is set to a value indicating the BCD format.

  On the other hand, among the display component objects O1a,..., The display component object O1d is a display component object for displaying a character string, and is used to indicate the model of the device 3 in which the alarm has occurred. The device attribute AD of the display component object O1d is set to the address of the area for storing the data indicating the model of the device 3 of the alarm (in the above example, “D01003 to D01007”).

  Further, among the display component objects O1a..., The display component object O1e is a display component object for displaying numerical values, and is used for displaying the employee code of the operator when the alarm is generated. The device attribute AD of the display component object O1e is set to the address of the employee code area ("D01010" in the above example) of the alarm data of the alarm, and the display data format attribute AF is Dec format. Is set to a value indicating.

  Similarly, the display data format attribute AF of the display component objects O2a... And O3a... Indicating the second and third alarm data is the same as the corresponding display component object of the display component objects O1a. It is set to the same value. Note that the value of the device attribute AD of each display component object is changed to a value indicating a corresponding portion in the second or third alarm data. Further, the position attribute of each display component object including the display component object of the first alarm data stores data indicating the position on each operation screen. In the following, for convenience of explanation, a case will be described in which three pieces of alarm data are displayed on the operation screen. Of course, the number and contents of alarm data displayed on the operation screen are limited to this example. It is not a thing. Further, in FIG. 8, for the sake of convenience of explanation, the line spacing of each object is displayed with a gap from the actual distance.

  The history screen displays the next page, the previous page, and input operators O51, O53, and O52 that indicate buttons for instructing to end the display of the history screen, and a display component object O54 that indicates the current date and time.・ O55 is also arranged.

  Screen data including data for generating the object set as described above is stored in the graphic operation panel 14 and has, for example, the attribute set as described above according to the display instruction of the history screen. When each object is generated and it is determined that each display component object has reached the display timing, each display component object receives the alarm data stored in the memory 13a of the PLC 13 in the same manner as when the state of the device 3 is displayed. Acquire and display the contents. As a result, a list of alarm data is displayed on the display 21 of the graphic operation panel 14 as shown in FIG.

  Here, as described above, the display component objects O1a to O1c, O2a to O2c, and O3a to O3c are display component objects for numerical display, and the display data format attribute AF is set to BCD. Therefore, the display component objects O1a to O1c, O2a to O2c, and O3a to O3c are binarized 10 at the positions indicated by the position attributes AL on the operation screen of the display 21. For example, the value (“0011h”) stored in “D01001” is displayed as “11”.

  On the other hand, the display component objects O1e, O2e, and O3e are display component objects for numerical display, and the display data format attribute AF is set to Dec. Therefore, the display component objects O1e, O2e, and O3e display the data read from the respective device attributes AD as decimal data at the positions indicated by the respective position attributes AL on the operation screen of the display 21.

  For example, “D01010” stores the same value (“0011h”) as “D010001” described above, but this value is data to be expressed in decimal, unlike “D01010”. Therefore, the display component object O1d displays “17” unlike the display component object O1a.

  Since the display component objects O1d, O2d, and O3d are display component objects for displaying character strings, the data read from each device attribute AD at the position indicated by each position attribute AL on the operation screen of the display 21. Is displayed as a character string.

  Thereby, even if the data of various display data formats are stored in the memory 13a of the PLC 13, the graphic operation panel 14 can appropriately grasp each display data format and display it in the correct format.

  Furthermore, the control system 1 according to the present embodiment has the following configuration in order to print the device data in an appropriate format and to output the CSV without much effort.

  That is, a red frame object for printing / CSV output (hereinafter collectively referred to as data output) can be stored in the screen data according to the present embodiment. The red frame object O31 is for specifying an object to be data output, and is given a range attribute AA indicating a range in which the object to be data output should exist. Further, when the data output is instructed, the red frame object O31 is an operation for outputting the contents of the object related to the display among the objects existing within the range indicated by the range attribute AA, as will be described in detail later. Can be repeated.

  Further, the screen data includes data for generating an input object for instructing data output to the red frame object O31, and the input object receives an operation for instructing printing or CSV data output. For example, printing or CSV data output can be instructed to a preset red frame object as the attribute value.

  More specifically, the red frame object O31 is provided with ranges A11 to A45 arranged in a grid pattern as the range where the object of data output should exist, and the range attribute AA includes As a value indicating the shape and arrangement of the grid, a value indicating the position of each vertical frame configuring the grid and a value indicating the position of each horizontal frame configuring the grid are set.

  Here, in the example shown in FIG. 8, among the objects, the objects O51 to O55 such as a clock and a button are unnecessary when outputting data, and the character string objects O11a to O11e indicating the title and the display component object It is desired to output data O1a to O3e.

  In this case, as shown in FIG. 10, the red frame object O31 is set so as to indicate a grid-like range A11 to A45 of horizontal 5 columns × vertical 4 rows. More specifically, the lattice-shaped ranges A11 to A45 are specified by the vertical frames Fa to Ff and the horizontal frames F1 to F5. Accordingly, in the range attribute AA of the red frame object O31, for example, six values indicating the X coordinate of the vertical frames Fa to Ff and five values indicating the Y coordinate of the horizontal frames F1 to F5 are set. . The ranges A11 to A45 are set so as to include display areas of the objects O11a to O11e and the display component objects O1a to O3e.

  In addition, the red frame object O31 associates each range arranged in a grid with CSV records and fields in a predetermined procedure for outputting CSV data. Each field of the record is generated based on the contents of the object included in the range corresponding to each record, and the data of the record including those fields is generated from the data of each field. Data can be output in order.

  Although the above association may be determined by the attribute, in this embodiment, the correspondence is fixed, and for example, a range group (for example, range A11 to A15) arranged in one horizontal row corresponds to one record. A range included in the range group associated with each record is associated with a field determined by the position in the horizontal direction. For example, among the ranges A11 to A45, the ranges A11, A21, A31, and A41 arranged on the leftmost side in each row correspond to the first field of each record.

  In the present embodiment, each field is assigned an earlier order as the range corresponding to the left is the left. Each record is assigned an earlier order in the range group corresponding to the record. On the other hand, the red frame object O31 according to the present embodiment scans each range from left to right, and generates field data corresponding to each range. In addition, the red frame object O31 collects field data for one line by, for example, connecting the data of each field via a predetermined field separator. Thereby, data of one record is generated. Further, the red frame object O31 repeats this operation in order from the upper row (range group), and, for example, concatenates the data of the records in each row by connecting them through a predetermined record separator. Thereby, the red frame object O31 can generate data of the designated record group.

  In addition, the red frame object O31 according to the present embodiment displays the next screen (next page) in a predetermined procedure when the data output of the contents of all the objects existing in the range indicated by the range attribute AA is completed. The red frame object can be searched and data output can be instructed to the red frame object. In this embodiment, as an example, each operation screen is given a predetermined consecutive number, and the red frame object is arranged when the next red frame object is searched. It is determined whether or not a red frame object is arranged on the next screen (the next number screen) of the operation screen being displayed, and if so, data output is instructed to the red frame object. On the other hand, if it is not arranged, the data output operation is finished at that time.

  Here, when a plurality of history screens having the same layout as in FIG. 10 are set, the character string objects O11a to O11e indicating the title are output only in the case of the first screen, and are displayed in the case of the remaining screens. It is desirable not to output.

  Accordingly, the red frame object O31 is also provided with a page attribute AP indicating whether data is output only on the first screen or on all screens for each range. In the case of the first screen, for example, when the data output instruction is received from the input object described above, the object O31 outputs the content of the object regardless of the value of the page attribute AP. On the other hand, for example, when a data output instruction is received from another red frame object, and when it is not the first screen, only when the page attribute AP is in a range indicating data output on all screens. The contents of the object within the range are output as data. If the range indicates that the data is output only in the first screen, the contents of the object within the range are not output as data. As a result, even when a plurality of history screens are set, the title is output as data for the first screen, and the title data output of the remaining screens can be prevented.

  In the above configuration, when data output is instructed, in S1 shown in FIG. 1, the red frame object O31 determines whether or not an unprocessed range exists. If an unprocessed range is found, the red frame object O31 is arranged on the first screen, or even if the red frame object O31 is not arranged on the first screen, the page attribute AP of the red frame object O31. When the value of indicates that the object of the range is output on all screens (YES in S1 or YES in S3), the red frame object O31 is within the range in S11. It is determined whether or not an object (in this embodiment, a display component object or a component object) that is predetermined as an object related to data output is arranged, and if it does not exist (NO in S11), In S12, a value indicating no data (for example, a blank character code or a NULL code) is output, or the data And or suspends output itself, it performs the processing when there is no data.

  The red frame object O31 outputs the character string indicated by the character string object in S14 when the character string object exists within the above range (YES in S11 and character string in S13). To do.

  Further, the red frame object O31 indicates the state of the device indicated by the display component object in S15 when the display component object exists within the above range (YES in S11 and display component in S13). Is acquired, and the acquired value is processed as data in the display data format indicated by the display component object.

  The processes in S1 to S15 are repeated until there is no unprocessed range (until NO in S1). When there is no unprocessed range (in the case of YES in S1 above), the red frame object O31 searches for a red frame object in the next screen in S21 and if found (if YES in S21), is found. The process after S1 is instructed to the red frame object.

  Here, the red frame object O31 is arranged on the second and subsequent screens, and the value of the page attribute AP of the red frame object O31 indicates that data in that range is output only on the first screen. In the case (NO in both S2 and S3), the red frame object O31 does not perform the processes after S11, and repeats the processes after S1.

  The processes in S1 to S21 are repeated until the red frame object on the next screen is found (YES in S21). If the red frame object on the next screen cannot be found, the red frame object Ends the process.

  Note that the processing of S12, S14, and S15 includes output processing of field separators and record separators in CSV output, or line feed processing in printing, and the red frame object O31 has its range in the case of CSV output. If the field corresponding to is the last field of the record corresponding to the range, a record separator is output, and if it is not the last field, the field separator is output. In the case of printing, when the field corresponding to the range is the last field of the record corresponding to the range, the red frame object O31 instructs a printer (not shown) to perform a line feed.

  For example, in the example of FIG. 10, as described above, since the unprocessed range is searched by repeating the operation of scanning the range from the left to the right in order from the upper row, first, the upper left The character string object O11a arranged in the range A11 is found, and then the character string objects O11b to O11e are found sequentially. Therefore, when CSV data output is instructed to the red frame object O31, the data ““ year ”,“ month ”,“ day ”,“ model ”,“ employee number ”is displayed as shown in P1 of FIG. Finally, a line feed code as a record separator is output.

  Next, the red frame object O31 finds the display component objects O1a to O1e as objects included in the ranges A21 to A25. In this case, the red frame object O31 acquires, for example, the device attribute AD and the display data format attribute AF of each display component object O1a to O1e. Further, the red frame object O31 acquires the state of the device indicated by the device attribute AD in the same manner as the display component objects O1a to O1e, and also displays the value as display data format data indicated by the display data format attribute AF. Process. As a result, the data “2004, 11, 8,“ YAS-ABC123 ”, 17” is output as indicated by P2 in FIG.

  Here, as described above, when the display frame object is included in the range set by itself, the red frame object acquires and acquires a value indicating the state of the device indicated by the display component object. The processed value is processed as data in the display data format indicated by the display component object.

  Therefore, if the device and the display data format are set for the display component object, the red frame object is suitable for the CSV output and printing without any problem even if these data are not newly set. Data can be output in various display data formats, reducing the setting effort.

  The red frame object outputs the contents of the display component object or the character string object included in the range set for itself. On the other hand, even if it is a display component object or a character string object, the red frame object does not output data as long as it is not included in the range of the red frame object. Therefore, it is necessary for display as shown in FIG. 10, for example, as shown in FIG. 10, unlike the configuration for capturing the history screen, although the data is output with reference to the information set in the display component object. However, data output can be stopped for data that is not required for data output.

  Hereinafter, a configuration for setting a red frame object and an operation at the time of setting the red frame object will be described with reference to FIGS. 5, 10, 12, and 13. That is, the editing processing unit 72 according to the present embodiment is configured to accept a red frame object placement operation in addition to the above-described objects, for example, by displaying a palette of red frame objects. In addition, when the editing processing unit 72 receives an arrangement operation of the red frame object by the user, the editing processing unit 72 stores the red frame object data in the storage unit 71 so that the screen data being edited includes the data of the arranged red frame object. The content is changed, and the display processing unit 73 displays the red frame object in the designated coordinate range based on the content of the storage unit 71.

  As described above, a grid-like range is set for the red frame object according to the present embodiment. Accordingly, the edit processing unit 72, for example, displays the number of rows and columns by changing the initial values of the predetermined number of rows and columns, for example, at the time when the placement operation is received. Prompt the user to enter a number. Further, upon receiving an input operation for the number of rows and the number of columns, the editing processing unit 72 sets the input values as the number of rows and the number of columns of the red frame object. Note that the edit processing unit 72 receives the number of rows or the number of columns according to the input operation of the number of rows and the number of columns from the user when the change operation of the number of rows or the number of columns is received after the red frame object is arranged. The number of columns may be changed.

  Further, in this embodiment, when the number of rows and the number of columns is input from the user, the editing processing unit 72 causes the red frame so that the column width of each column and the row height of each row become predetermined values. The range attribute AA of the object O31 is set. In the present embodiment, as an example, the initial value of the column width of each column is set to the same value, and the initial value of the row height of each row is set to the same value.

  Furthermore, after arranging the red frame object O31, the editing processing unit 72 accepts an operation for changing the position of each vertical frame and horizontal frame of the red frame object O31, such as a drag and drop operation to the vertical frame or the horizontal frame. Then, the value of the range attribute AA of the red frame object O31 can be changed to a value according to the operation.

  Here, when the drawing processing unit 61 is editing the history screen shown in FIG. 8, when the generation of a red frame object is instructed and 4 and 5 are input as the number of rows and the number of columns, the display processing unit 73. As shown in FIG. 12, a red frame object O31 in which each vertical frame and each horizontal frame are equally allocated is displayed. However, in this state, the objects O11a to O11e / O1a to O3a to be output and the ranges A11 to A45 of the red frame object O31 are in an inappropriate positional relationship, and the objects O11a to O11e / O1a to O3a to be output are inadequate. Among these, there are those protruding from the ranges A11 to A45 (in the example of FIG. 12, objects O11d, O1d, O2d, and O3d).

  In this state, when the user moves the vertical frame Fe to the right so that these objects do not protrude and the edit processing unit 72 changes the value of the range attribute AA accordingly, the display processing unit 73 As shown in FIG. 13, the respective objects O11a to O11e and O1a to O3a are in the respective ranges A11 to A45 of the red frame object O31.

  Furthermore, the edit processing unit 72 arranges an input object O21 that receives a data output instruction to the red frame object O31 in accordance with a user operation, as in the case of input objects such as other buttons, as shown in FIG. A screen on which buttons for instructing data output are arranged is designed.

  As described above, in the control system 1 according to the present embodiment, the red frame object O31 determines whether or not a predetermined type of object is arranged within the range. The contents of the object are output as data. When the object is a display component object, the red frame object O31 acquires a value indicating the state of the device indicated by the display component object, and the acquired value is a display data format indicated by the display component object. The data is processed and output as data.

  Therefore, the data displayed on the history screen can be processed in the same format as the display without modifying the screen data of the history screen designed so far. As a result, it is possible to greatly reduce the time and effort required when designing a history screen capable of outputting data.

  In the above, when each red frame object searches for a red frame object to which data is to be output next, it searches for a red frame object arranged on the screen next to the screen on which it is arranged. This is not a limitation. For example, in accordance with a user instruction, the drawing editor device 16 sets information indicating a red frame object to which data is to be output next to each red frame object, for example, as an attribute and the like. When there is no object, a predetermined termination code may be set in the attribute or the like. In this case, the red frame object refers to the value of the attribute and determines whether or not there is a next red frame object. If there is a next red frame object, the red frame object can instruct data output to the red frame object.

  In the above description, the case where the objects corresponding to the data of each field of one record are arranged on one display screen and one red frame object has been described as an example. However, the present invention is not limited to this. For example, objects corresponding to the data of each field of one record may be arranged in a plurality of red frame objects.

  In this case, for example, the drawing editor device 16 associates each red frame object arranged on a different screen in accordance with a user instruction, and stores the relationship in, for example, the attribute of each red frame object. On the other hand, when outputting the data of each record, each red frame object refers to the attribute when the data output for one record is completed in each range indicated by its range attribute AA. Is identified, and the red frame object is instructed to output another field of the record. When a value indicating the last is stored in the attribute, the red frame object is determined to be the last one of the red frame objects in which the record data is distributed, for example, , Process the last case of the record, such as outputting a record separator. Thereby, for example, even if objects corresponding to the data of each field of one record are distributed and arranged in a plurality of red frame objects arranged on different screens, the data of each field can be output without any trouble.

  Furthermore, in the above, a large classification of the display data format (for example, whether it is displayed as a numerical value or a graph) is set according to the type of the display component object, and the display data format attribute is set to a small display data format attribute. Although the configuration for setting the classification has been described, the configuration is not limited to this. The drawing editor device 16 may set these combinations as display data format attributes, or may set these combinations depending on the type of display component object.

  Moreover, although the case where the combination of device information, position information, and display data format information was memorize | stored according to the object and its attribute was demonstrated above, it is not restricted to this. The drawing editor device 16 may store these information in association with each other by another method, for example, by storing these information as each field of the relational database.

  In any case, device information, position information, and display data format information are stored in association with each other, and the graphic operation panel 14 controls the device specified by the device information as display processing. It communicates with the apparatus to acquire the value of the device, and the display data format information stored in association with the device information indicates the position indicated by the position information stored in association with the device information on the screen. The same effect can be obtained as long as the process of displaying the acquired value in the form is performed.

  Note that each of the members 23 to 26 and members 31 to 33, 61 to 63, and 71 to 74 described later execute a program stored in a storage unit such as a ROM or a RAM by a calculation unit such as a CPU. These are functional blocks realized by controlling input / output means such as the display 21 and the touch panel 22 or communication circuits such as interface circuits. Of these members, each of the storage units 25, 62, and 71 may be a storage device such as a ROM or a RAM.

  Therefore, the computer having these means reads the recording medium (for example, CD-ROM) on which the above-mentioned program is recorded and executes the program. The drawing editor device 16 can be realized. For example, if a program for downloading a program via the LAN 12 or another communication path is installed in the computer in advance, the program is distributed to the computer via the communication path. You can also.

  It can be widely used for display devices such as a programmable display and drawing devices for the display devices.
