Description

  The present invention relates to an editor device, a program, and a recording medium on which an editor device that facilitates changing an address of a component included in an image displayed on a programmable display.

  The programmable display has an interface with a programmable logic controller (PLC), displays the operating status of devices connected to the PLC, and accepts operation inputs from the screen to give control instructions to the devices. It is an operation type display with a function to In general, since the programmable display has a graphic display function, it can display an operation panel, a switch, an indicator lamp, and the like, and serves as an operation terminal in the control system.

  The user image displayed on such a programmable display can be created by the user by using image creation software (drawing software) according to the specifications of the control system. When creating an image, a user configures a desired image using an editor device such as a personal computer using components, drawing functions, and the like provided by drawing software.

  The above parts are images representing switches, numeric keys, meter displays, graph displays, etc., and are prepared in advance in drawing software in a library format so that they can be combined and handled as actual parts. In addition, the above-described component is used in combination with an image representing the component and setting data for expressing the dynamic change of the image at a designated position on the screen. The setting data is stored in the memory of the programmable display as part of the image data.

  The created image is transferred to the programmable display as image data and stored. When the PLC is in operation, output components such as a meter display on the screen displayed on the display unit of the programmable display dynamically change according to the state of the device connected to the PLC. Further, an input operation on the screen to an input component such as a switch is given to the device as a control instruction.

  In the drawing software, the address of the memory in the PLC that stores the device data is usually used to reflect the device status on the screen display and the input instruction via the component to the device status. Set to.

  FIG. 10 shows a conventional image creation window 200. In the address setting, the components 202 arranged in the drawing area 201 of the image creation window 200 are selected one by one, and the address is input to the address input field 211 of the setting window 210 shown in FIG. After inputting the address, the user presses an OK button 212 to set the address for the selected component 202.

  When changing the already set address, each component 202 is selected to display the setting window 210, the address in the address input field 211 is rewritten, and the OK button 212 is pressed. This procedure is performed for each component 202 whose address is to be changed.

Further, in Patent Document 1, as shown in FIG. 12, a configuration for displaying a list 300 of component functions and addresses is disclosed. Thereby, the user can easily grasp the address of each component. Patent Document 2 discloses a configuration for displaying a list of available addresses.
Japanese Patent Laid-Open No. 11-327616 (released on November 26, 1999) JP 2006-99568 A (published April 13, 2006)

  However, in many cases, the number of parts arranged in the user image ranges from tens to hundreds. Therefore, in the configuration shown in FIGS. 10 and 11 and the configuration of Patent Document 2, since the address is set / changed for each part, it takes time to change the address, and to what part the address has been changed. I can't figure it out. Further, when the address is changed by opening the setting window 210 shown in FIG. 11, once the address in the address input field 211 is rewritten, the cancel button 213 is pressed again to confirm the address before rewriting. The setting window 210 needs to be opened. At this time, in the setting window 210 reopened, all the setting items including the address are returned to the state before rewriting, which causes a problem that work efficiency is reduced.

  Japanese Patent Application Laid-Open No. 2004-228561 discloses a configuration for setting an address for each component, but does not disclose a configuration for inputting an address to the list 300. Therefore, when the number of parts increases, it takes time to change the address. In addition, since only the address information at the time when the list 300 is opened is displayed in the list 300, when changing the addresses of a plurality of parts, it is difficult to grasp which part of the address has been changed.

  The present invention has been made in view of the above problems, and an object of the present invention is to realize an editor device capable of easily changing the device address.

  In order to solve the above problems, an editor device according to the present invention edits image data for displaying a state of a device as a component graphic on a display screen of a programmable display connected to a control device that controls the device. An image creation means for creating a user image in which the component graphic is arranged, an identification number of each component graphic selected in the user image, a function assigned to the component graphic, and the component A list display means for displaying a list of addresses of devices corresponding to the figure, and an address changing means for changing the address, wherein the address of the device at the time of selection of the part figure is displayed in an unrewritable manner. The first address field and the device address at the time of selection of the part graphic can be rewritten. The address changing means changes the address displayed in the first address field to the rewritten address displayed in the second address field. .

  According to the above configuration, when changing the address of the device corresponding to the component graphic arranged in the user image, when the component graphic arranged in the user image is selected, the list display means selects each component graphic selected. A list of device addresses corresponding to the identification number, function, and part graphic is displayed. By displaying the identification number and the function, the user can specify the address to be changed. The list is provided with a first address field in which the address at the time of selection of the component graphic is displayed in a non-rewritable manner and a second address field in which the address at the time of selection of the component graphic is displayed in a rewritable manner. The address changing means changes the address displayed in the first address field to the rewritten address displayed in the second address field. That is, since the address can be changed by rewriting the address in the second address column of the list, the address changing operation is performed as compared with the case where the address is changed by individually selecting a part figure as in the past. Can be reduced. Furthermore, the user can rewrite the address in the second address field while confirming the address before the change displayed in the first address field, so that any part figure can be changed even during the address change work. It ’s easy to see if you ’ve gone. Therefore, there is an effect that an editor device capable of easily changing the device address can be realized.

  In the editor device according to the present invention, it is preferable that the editor device includes a change permission / non-permission determining unit that determines whether the address change by the address changing unit is performed for each part graphic.

  According to the above configuration, it is possible to set whether or not the address can be changed for each part graphic. For example, when performing batch conversion with an offset, it is possible to prevent an address that should not be changed from being erroneously changed.

  The program according to the present invention is a program that causes a computer to operate as each unit of the editor device, and the program is recorded on the recording medium according to the present invention.

  As described above, the editor device according to the present invention edits image data for displaying the state of the device as a component graphic on the display screen of a programmable display connected to the control device that controls the device. An image creating means for creating a user image in which the component graphic is arranged, an identification number of each component graphic selected in the user image, a function assigned to the component graphic, and the component graphic A list display means for displaying a list of addresses of devices to be changed, and an address change means for changing the addresses. The address field and the address of the device at the time of selection of the part graphic are displayed in a rewritable manner. The address changing means changes the address displayed in the first address field to the rewritten address displayed in the second address field, so that the device address can be easily changed. There is an effect that a possible editor device can be realized.

  An embodiment of the present invention will be described below with reference to FIGS.

  As shown in FIG. 1, the control system 1 according to the present embodiment includes a host computer (editor device) 2, a programmable display 3, a PLC (control device) 4, a common network 5, a dedicated network 6, Device 7.

  The host computer 2 and the programmable display 3 are connected to each other via a common network 5. On the other hand, the programmable display 3 and the PLC 4 are connected via a dedicated network 6. The common network 5 is a network such as a local area network (LAN) made of Ethernet (registered trademark) or the like capable of performing communication using a common communication protocol (common communication protocol). The dedicated network 6 is a network composed of a serial cable or the like that can perform communication using a communication protocol (dedicated communication protocol) unique to the PLC 4. The dedicated communication protocol is often different for each PLC4 model, such as for each manufacturing company or for each product even if it is the same company, because the PLC4 has been developed from a sequencer.

  The control system 1 according to the present embodiment connects the programmable display 3 and the host computer 2 respectively connected to each PLC 4 through a common network 5 and uses a dedicated communication protocol as a common communication protocol used in the common network 5. Adopts a common protocol defined independently. Furthermore, as will be described later, the programmable display 3 also has a function of converting a protocol, for example, by performing protocol conversion such as instruction code conversion, argument conversion, or control code conversion during transmission, The communication between the host computer 2 and the PLC 4 connected to the own device is relayed.

  In such a configuration, the programmable display device 3 operates as an HMI, and therefore has more computing power than the PLC 4, and therefore handles most of the communication. For example, it is possible to communicate directly from the host computer 2 to the programmable display 3 without going through the PLC 4 like downloading image data. Therefore, the burden on the PLC 4 can be reduced, and the calculation capability required for the entire control system 1 can be reduced. Note that the programmable display 3 has a sufficient computing capacity while waiting for an operator's operation, so that protocol conversion can be performed without improving the computing capacity for protocol conversion.

  The PLC 4 captures output data output from the input device 7 via the input unit according to a control program (ladder program) created by the user, and gives the control data to the output device 7. As the input device 7, devices such as sensors (temperature sensors, optical sensors, etc.) and switches (push button switches, limit switches, pressure switches, etc.) are used. As the output device 7, an actuator, a relay, a solenoid valve, a display, or the like is used. These devices 7 are arranged in required portions of various target systems such as a production line. Further, the device 7 may be a specific area in the memory unit 32 described later for storing data manually input from an input device such as a touch panel 33 described later.

  The memory (device memory) in the PLC 4 stores data (word data and bit data) such as the state of the device 7 and the setting value of the device 7 in an area designated by the device address. In the memory, a word device is set as an area for storing word data such as numerical values as input / output data, and is designated by a word address (device address). The bit device is set as an area for storing bit data such as an on / off state, and is set by a bit address (device address). With such a setting, it is possible to control the devices 7 simply by accessing an arbitrary word device or bit device in the PLC 4, or to individually retrieve information relating to the state thereof.

  In the following description, the device address is appropriately referred to as an address.

  The programmable display 3 includes an arithmetic processing unit such as a CPU, and realizes an operation function and a display function specific to the programmable display by executing a program (image data) for input operation and display created by the user. It is a computer. The programmable display 3 suitably used as the HMI of the control system 1 is an operation for displaying the state of the device 7 on the screen based on image data determined by combining processing instructions (tags) described later, The operation for controlling the state of the device 7 in accordance with the operation on the screen is specified. The programmable display device 3 acquires the state of each device 7 that displays the state on the display screen via the PLC 4 connected to the device 4 through communication with the PLC 4 via the dedicated network 6. -34 has a function of displaying the status of each device 7. The programmable display 3 has a function of instructing the device 7 to control the state of the device in response to an operation on the touch panel 33 described later.

  The acquisition / change of the state of the device 7 may be instructed each time, or a cache is prepared in the programmable display 3, and the cache is accessed at the time of acquisition / change, and at predetermined time intervals or at predetermined intervals. Communication may be performed for each event to synchronize with the actual device address.

  The programmable display device 3 includes an HMI processing unit 31, a memory unit 32, a touch panel 33, a screen 34, and interface units (I / F in the figure) 35 and 36 in order to realize the above functions. Yes. Hereinafter, each main part of the programmable display 3 will be described in detail.

  The touch panel 33 is an input device provided for performing input on the display screen of the screen 34. The screen 34 is preferably a flat screen such as a liquid crystal screen or an EL screen in order to make the programmable display 3 thin.

  The interface unit 35 is a communication control unit for the programmable display 3 to communicate with the host computer 2 and the like on the common network 5, and is connected to the common network 5. Data is transmitted to and from the host computer 2 through communication via the common network 5. On the other hand, the interface unit 36 is a communication control unit for the programmable display 3 to communicate with the PLC 4, and is connected to the dedicated network 6. Data is transmitted to and from the PLC 4 by communication via the dedicated network 6.

  In the communication system configured as described above, output data from the PLC 4 is transmitted to the programmable display 3 and further connected to the host computer 2 or the common network 5 via the programmable display 3 ( (Not shown). Further, not only the data set in the programmable display 3 is directly transmitted to the PLC 4, but also the setting data transmitted from the host computer 2 or other devices is connected to the PLC 4 as the communication destination. Is transferred to the PLC 4 via.

  The HMI processing unit 31 performs various types of data processing to perform user image display control and protocol conversion processing, which will be described later.

  The protocol conversion process is a process of converting from one communication protocol to the other communication protocol while referring to protocol conversion data described later stored in the memory unit 32 when the communication protocols in the both networks 5 and 6 are different from each other. is there. The protocol conversion process is realized by executing a protocol conversion program stored in the memory unit 32 by an arithmetic processing unit such as a CPU.

  In addition to the display control system program, protocol conversion data, and communication protocol, the memory unit 32 stores image data transferred from the host computer 2.

  The display control system program is a program for realizing a basic function for performing image display control.

  The protocol conversion data may be in any format as long as the communication protocol can be mutually converted between the dedicated network 6 and the common network 5, but in the present embodiment, data indicating the format of data transmitted on the dedicated network 6 A transfer format and a command conversion table indicating the correspondence between command codes transmitted in both networks 5 and 6 are stored.

  The communication protocol (dedicated communication protocol) is a protocol used in communication processing with the PLC 4, and is uniquely determined according to the model (manufacturer) of the PLC 4. This communication protocol includes a command code that instructs reading of data to the PLC 4. By combining this command code with an address associated with the control function of the PLC 4, data about a desired control function can be transmitted to the PLC 4.

  The image data D is data of an image displayed on the programmable display 3, and includes a base image to be displayed on the screen 34, component data, a processing instruction word W described later assigned to each component, and the like. Yes. The image data D is created / edited by the drawing editor unit 25 described later and downloaded to the memory unit 32. The image data D is stored in the memory unit 32 as an image file in the form of a file, and is composed of graphic data DG and address data DA. The graphic data DG includes component data, a character string, a processing instruction word W, a comment corresponding to the address, and the like. The address data DA includes the addresses set in the drawing editor unit 25 for data associated with addresses such as component data and processing instruction word W in the graphic data DG.

  A comment included in the graphic data DG is composed of a function of a part and an ID (identification number) obtained by combining a code and a number corresponding to a switch or lamp.

  As shown in FIG. 2, a processing instruction word (tag) W included in the image data D is created for each event to be executed on the base image. The processing instruction word W basically includes a file number F of a base image on which a display control operation is to be executed, an event name T for specifying the operation content to be executed on the base image, and each execution event. A set of reference information I including one or a plurality of data to be referred to is provided.

  In the programmable display device 3 according to the present embodiment, as the above-described tag, a display tag indicating the correspondence between the region (display range) on the base image and the device address of the device corresponding to the display in the region, and the image An input tag indicating the correspondence between an area (input range) and an address corresponding to a touch input to the area is defined. Furthermore, in this embodiment, each tag can be associated with at least one of a plurality of user images.

  The display tag can display a predetermined graphic at a corresponding position on the base image in conjunction with the operation of the touch panel 33. That is, the display tag includes the file number of the base image as the file number F, the event name that specifies the display of the display target such as a graphic as the event name, the file that specifies the display coordinate range of the display target and the display target to be called It includes a number and an address for referencing the display target when displaying.

  The input tag enables the bit device to be reversed in conjunction with, for example, a touch operation on the touch panel 33. That is, the input tag includes the file number of the user image as the file number F, the event name specifying the operation of the touch panel 33 as the event name T, and the input coordinates that validate the input operation from the touch panel 33 as the reference information I The range and the address to which data should be rewritten in conjunction with the touch operation on the touch panel 33 are included.

  The display control function of the HMI processing unit 31 is configured to display image data, set various data to the user image, transmit the set data to the PLC 4, and display the data received from the PLC 4 on the user image. This display control system program is realized by causing an arithmetic processing means such as a CPU included in the programmable display 3 to execute the display control system program. This display control function extracts display tags related to the currently displayed user image from the image data, and reads the contents of the device addresses related to each display tag at predetermined intervals for display tags. The part of the expression format specified by the tag is displayed in the specified area on the screen in a form corresponding to the read value. On the other hand, when the display control function receives an input operation on the touch panel 33, the display control function searches the image data for an input tag corresponding to the currently displayed user image and matches the input operation, and indicates a device address indicated by the input tag. (Data stored in the memory area specified by the device address) is rewritten according to the input result. As a result, the programmable display 3 displays the state of the device 7 indicated by the image data at a display position (parts etc.) indicated by the image data in an expression format indicated by the image data, or allows an input operation by a part etc. in the image data Can be controlled accordingly.

  Next, the host computer 2 will be described. The host computer 2 is a general-purpose personal computer, for example, and includes an interface unit (I / F in the figure) 21, a hard disk 22, a RAM (Random Access Memory) 23, a VRAM (Video Random Access Memory) 24, and a drawing editor. Part 25. Although not shown, the host computer 2 has input devices such as a display, a keyboard, and a mouse.

  The interface unit 21 is a communication control unit for performing communication with the programmable display 3 and is connected to the common network 5. The RAM 23 is a main memory that plays a role of temporarily storing data and providing a work area during arithmetic processing of the CPU. The VRAM 24 is a memory that temporarily holds an image image displayed on the display of the host computer 2.

  The hard disk 22 stores an editor program EP and image data D created by a drawing editor unit 25 described later.

  The editor program EP is recorded on a recording medium configured to be separable from the host computer 2 and can be installed in the host computer 2 from this recording medium. The recording medium is a computer-readable recording medium, such as a tape system such as a magnetic tape or a cassette tape, a magnetic disk system such as a flexible disk or a hard disk, an optical disk system such as a CD-ROM, MO, MD, or DVD, A card system such as an IC card (including a memory card) or an optical card is suitable. In addition, the program medium may be a medium that carries a fixed program including a semiconductor memory such as a mask ROM, EPROM, EEPROM, flash ROM, or the like.

  Further, since the control system 1 has a system configuration that can be connected to a communication network including the Internet, the control system 1 may be a medium that dynamically carries the program so as to download the program from the communication network. However, when the program is downloaded from the communication network in this way, the download program may be stored in the host computer 2 in advance or may be installed from another recording medium.

  When the editor program EP is activated, a drawing editor unit 25 for creating and editing the image data D is generated. Thereby, the host computer 2 functions as an editor device.

  The drawing editor unit 25 includes an image creation unit 251 and an address setting unit 252. The address setting unit 252 includes a list display unit 252a, an address conversion unit 252b, a conversion availability determination unit 252c, a storage execution unit 252d, and a conversion cancellation unit 252e.

  The image creation unit 251 includes components such as switches, lamps, numeric keys, and various displays (for example, a numerical display, a meter display, and a graph display) so that a user image that is a user-specific image can be created and edited. It has creation and editing functions such as various tag setting functions, drawing functions, and text input functions. As components, not only components having a single function but also components having a plurality of functions such as a composite switch, a counter, and a timer are prepared. Parts as display elements are registered in a library format so that the user can easily select them, and input tags, display tags, and the like corresponding to the functions of the parts are assigned in advance. The drawing function is used to draw line and curved line figures (display elements), to draw basic figures (display elements) such as circles, rectangles, and triangles, and to fill them with specified colors and patterns in the figure. It is a function. In addition, the image creation unit 251 configures one user image file PF by combining the data of each element configured on the base image into one.

  When the editor program EP is activated and the drawing editor unit 25 is generated, the image creation unit 251 reads the graphic data DG and the address data DA of the image data D stored in the hard disk 22 into the RAM 23. As a result, the drawing window 100 shown in FIG. 3 is displayed on the display of the host computer 2.

  Here, in FIG. 1, the address data read from the hard disk 22 to the RAM 23 is shown as pre-edit address data DA1. The post-edit address data DA2 indicates the address data edited by the address setting unit 252 and is not created when the editor program EP is activated.

  The drawing window 100 includes an editing area 101 and an image list area 102. The editing area 101 is an area for arranging components 103 such as switches and lamps. The image list area 102 is an area for displaying a list of the user image files PF.

  Here, when the address set in the part 103 is edited, the part 103 whose address is to be edited is selected, and, for example, as shown in FIG. 4, the “address conversion” menu of the “edit” menu is selected. As a result, the list display unit 252a of the address setting unit 252 retrieves the ID / function data and address data of the selected component 103 from the graphic data DG and the pre-edit address data DA1 in the RAM 23, and develops them in the VRAM 24. . In FIG. 1, the address data expanded in the VRAM 24 is shown as pre-conversion address data DA1a and variable address data DA1b, and the ID / function data expanded in the VRAM 24 is shown as ID / function data DG1. .

  At this time, the address conversion window 110 shown in FIG. 5 is displayed on the screen of the host computer 2. The address conversion window 110 includes an address list 111, a selection button 112, a clear button 113, a conversion button 114, and a cancel button 115. The address list 111 includes a pre-conversion address field (first address field) 111a, a post-conversion address field (second address field) 111b, an ID field 111c, and a function field 111d. The pre-conversion address column 111a, post-conversion address column 111b, ID column 111c, and function column 111d display the pre-conversion address, post-conversion address, ID, and function of each selected component 103. The pre-conversion address column 111a and the post-conversion address column 111b correspond to the pre-conversion address data DA1a and variable address data DA1b developed in the VRAM 24, respectively, and the ID column 111c and the function column 111d are IDs developed in the VRAM 24. Corresponds to the function data DG1.

  When the address conversion window 110 is opened, the address displayed in the pre-conversion address field 111a and the address displayed in the post-conversion address field 111b are the same. Further, the address displayed in the pre-conversion address field 111a cannot be rewritten, and only the post-conversion address field 111b can be rewritten. When the user refers to the ID column 111c and the function column 111d and selects the post-conversion address column 111b of the desired component 103 and inputs an address, the variable address data DA1b developed in the VRAM 24 is rewritten. Subsequently, when the conversion button 114 is pressed, the address conversion unit 252b shown in FIG. 1 reads the rewritten variable address data DA1b into the RAM 23, and generates post-edit address data DA2. At the same time, the pre-conversion address data DA1a and the ID / function data DG1 developed in the VRAM 24 are erased from the VRAM 24, and the address conversion window 110 is closed.

  As described above, in this embodiment, the address of the selected component 103 can be collectively changed by displaying the address conversion window 110 and rewriting the post-conversion address field 111b of the address list 111. Therefore, it is possible to reduce the labor for changing the address as compared with the conventional case where the part graphic is individually selected and the address is changed.

  In addition, since the user can change the address while checking the address before change displayed in the pre-conversion address field 111a, which part address is input even during the change work? Can be easily grasped.

  In the address conversion window 110, after the input to the post-conversion address field 111b, the cancel button 115 is pressed to cancel the input contents. Accordingly, the conversion canceling unit 252e shown in FIG. 1 deletes the pre-conversion address data DA1a, the variable address data DA1b, and the ID / function data DG1 from the VRAM 24 without reading the variable address data DA1b into the RAM 23, and the address conversion window 110. Is closed.

  Next, a specific example of the user's address conversion operation will be described with reference to FIGS.

  For example, when the changed address corresponding to the ID “SL — 0000” and the function “bit-momentary” on the first line of the address list 111 shown in FIG. 5 is input and “M0100” is input, conversion is performed as shown in FIG. Only the rear address is rewritten to “M0100”.

  In addition to selecting the converted address fields 111b one by one and converting them individually as described above, it is also possible to perform conversion with offset by selecting a plurality of converted address fields 111b. For example, when the changed address on the first to fourth lines of the address list 111 shown in FIG. 5 is selected and “M0100” is input as the changed address on the first line, the second to fourth lines are displayed as shown in FIG. The post-conversion addresses are also collectively converted with an offset. Thereby, efficiency of conversion work can be achieved.

  On the other hand, for example, it is usually not preferable to change the address of a component having an interlock function. Therefore, in order to prevent accidental conversion of the address of the component having the interlock function, the address list 111 is provided with a check box 111e corresponding to each component 103, and the conversion possibility shown in FIG. The determination unit 252c determines whether or not an input to the post-conversion address field 111b can be accepted according to ON / OFF of the check box 111e.

  In the initial image of the address conversion window 110, all the check boxes 111e are ON, and only the address of the component whose check box 111e is ON can be changed. When turning off the check box 111e, the clear button 113 is pressed after selecting the corresponding check box 111e. As a result, the post-conversion address field 111b of a component for which the check box 111e is OFF cannot be rewritten, and an address that should not be converted can be prevented from being erroneously converted.

  When the address conversion unit 252b reads the rewritten variable address data DA1b into the RAM 23 and the edited address data DA2 is generated, the address data DA of the image data D stored in the hard disk 22 has been rewritten. Absent. Therefore, in the drawing window 100 shown in FIG. 3, for example, when the “Save” menu of the “File” menu is selected, the save execution unit 252 d shown in FIG. 1 selects the address data DA stored in the hard disk 22. The contents of the address of the part 103 are updated to the contents of the edited address data DA2. Thereby, the contents of the address after conversion are stored in the hard disk 22.

  Further, when the user wants to return to the contents before conversion after pressing the conversion button 114 in the address conversion window 110, for example, in the drawing window 100 shown in FIG. After that, for example, when the “Save” menu of the “File” menu is selected and saving to the hard disk 22 is executed, the save executing unit 252d uses the contents of the address data DA1 before editing instead of the address data DA2 after editing. Is overwritten on the address data DA. As described above, even after the address conversion, the pre-edit address data DA1 remains in the RAM 23 as a history, so that it is not necessary to input the content before the conversion again when it is desired to cancel the content of the address conversion.

  In the drawing window 100, when “address conversion” in the “edit” menu is selected without selecting the part 103, the address list 111 of the address conversion window 110 is displayed in the editing area 101 of the drawing window 100. The pre-conversion address, post-conversion address, ID, and function of all the components 103 that are present are displayed. The address conversion window 110 can also be displayed by selecting “address conversion” from the right-click menu instead of selecting “address conversion” from the “edit” menu.

  Next, the address conversion procedure according to this embodiment will be described with reference to FIGS.

  FIG. 8 is a flowchart showing the first half of the address translation. First, when the editor program EP is activated, a drawing editor unit 25 is formed, and a drawing window 100 is displayed on the screen of the host computer 2 (step S1). Subsequently, for example, when the “address conversion” menu of the “edit” menu is selected and the user instructs address conversion (step S2), when the component 103 is selected in the drawing window 100 (“YES” in step S3). 1) The list display unit 252a shown in FIG. 1 searches the ID / function data and address data of the selected component 103 (step S4). On the other hand, when the part 103 is not selected in the drawing window 100 (“NO” in step S3), the list display unit 252a displays the ID / function data of all the parts 103 displayed in the editing area 101 of the drawing window 100. Then, the address data is searched (step S5). Thereby, the address conversion window 110 is opened on the display, and the address list 111 is displayed (step S6).

  FIG. 9 is a flowchart showing the second half of the address conversion. The user inputs a post-conversion address (refers to an address to be set after conversion by the address conversion unit 252b. The same applies hereinafter) in the post-conversion address field 111b of the address list 111 (step S7), and the conversion button 114 is displayed. When pressed (step S8), the conversion feasibility determining unit 252c shown in FIG. 1 confirms ON / OFF of the check box 111e on the first line of the address list 111 (step S9). When the check box 111e is ON (“YES” in step S9), the address conversion unit 252b illustrated in FIG. 1 uses the ID / function described in the ID column 111c and the function column 111d corresponding to the check box 111e. Then, the part and the function of the part are specified (step S10), and the post-conversion address input to the post-conversion address field 111b corresponding to the check box 111e is read into the RAM 23 (step S11). If the check box 111e is OFF (“NO” in step S9), the steps S10 and S11 are omitted. Steps S9 to S11 are performed for each component in the address list 111, and the converted addresses input to the converted address column 111b of all the components in the address list 111 are read into the RAM 23 (in step S12, “ YES ”), the save execution unit 252d shown in FIG. 1 saves the edited address data DA2 read to the RAM 23 in the hard disk 22 (step S13). If there is a component whose post-conversion address input to the post-conversion address column 111b has not been read out to the RAM 23 ("NO" in step S12), for the component in the next row in the address list 111, the steps S9 to S11 are performed. Perform the process.

  In the address conversion procedure shown in FIG. 9, in step S7, the user can input to the post-conversion address field 111b while referring to the pre-conversion address field 111a. You can easily grasp whether you entered
