Description

  The present invention relates to a device management apparatus that manages field devices, and a computer-readable recording medium that records a program that realizes the functions of the device.

  Conventionally, in plants and factories, on-site equipment (measuring instruments, operating equipment) called field equipment and equipment management devices that manage and control these equipment are communicated via a communication bus in order to realize advanced automatic operation. A distributed control system (DCS) connected to each other is constructed. In such a plant, field devices provided by various manufacturers are often installed. However, when field devices having different specifications are mixed, management becomes difficult.

  Therefore, in recent years, from various manufacturers using device management devices using FDT (Field Device Tool) / DTM (Device Type Manager) technology or device management devices using EDDL (Electronic Device Description Language) technology. Unifying differences in the specifications of the field devices provided provides unified management. Here, the above FDT refers to an open interface specification for exchanging data between the device management apparatus and the field device without depending on the type of communication bus or communication protocol. An application that actually performs communication, setting, diagnosis, etc. for field devices. The EDDL is a language that describes characteristics and attributes of field devices.

  In general, the device management apparatus is realized by software in order to easily change or add specifications or functions. That is, a main application program that manages and controls field devices and a sub application program that is created using the above-described FDT / DTM technology and communicates with field devices in accordance with instructions from the main application. Are implemented on a computer. For details of a device management apparatus that manages and controls field devices installed in a plant or the like using FDT / DTM technology, see, for example, Patent Document 1 below.

Special table 2010-537513 gazette

  By the way, when setting parameters for a field device in a conventional device management apparatus, an administrator operating the device management apparatus selects a field device for parameter setting on the main application and sets the field device. It is necessary to repeat the process of inputting the parameters to be performed. This is due to the following reason. In other words, taking the FDT / DTM technology mentioned above as an example, DTM is a different application for each field device, so a frame application that exchanges information with this application (software that manages FTM-compliant DTM) This is because it is necessary to separately start (separate process).

  Here, the parameters of the field device are not only different depending on the model and the communication protocol, but are various because information specific to the manufacturer or the vendor may be incorporated even in the same model. For this reason, the DTM described above is provided for each field device having a different model and function, and different field devices having a similar model and function may be provided. Therefore, for example, even when setting parameters common to a plurality of field devices having slightly different functions, it is necessary to repeat the above-described work, and the administrator is forced to perform extremely complicated work. there were.

  In addition, if there are about several field devices for which parameters are to be set, the number of operations described above is only a few to a dozen or so, so there is a low possibility that an operation error will occur. However, as the number of field devices for which parameters are to be set increases, the number of required operations increases dramatically, which increases the possibility of managers' work errors, and ensures stable operation of plants and the like. There is a possibility of affecting the efficiency.

  The present invention has been made in view of the above circumstances, and can easily set parameters common to a plurality of field devices, thereby improving the stability and efficiency of a plant or the like.

The device management apparatus of the present invention is characterized in that the extraction unit extracts, as the common parameter, a parameter having the same type or a parameter having the same type and value from the parameters acquired by the acquisition unit. .
In the device management apparatus of the present invention, the setting instruction unit displays the common parameter extracted by the extraction unit together with information indicating the field device on the display device (2b) in a changeable manner. When a common parameter setting instruction is input from (2a), the setting of the common parameter displayed on the display device is instructed.
The recording medium of the present invention comprises a computer, a management control means (10) for managing and controlling field devices (1a to 1c), and a field device provided for each field device according to an instruction from the management control means.

  Hereinafter, an apparatus management apparatus and a recording medium according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of a device management system in which a device management apparatus according to an embodiment of the present invention is used. As shown in FIG. 1, the device management system MS includes field devices 1a to 1c and a device management device 2 connected via a communication bus B. The device management device 2 is connected to the field devices 1a to 1c. The communication via the communication bus B is performed to manage and control the field devices 1a to 1c. In FIG. 1, for the sake of simplicity, three field devices 1 a to 1 c are illustrated, but the number of field devices connected to the communication bus B is arbitrary.

  The field devices 1a to 1c are, for example, sensor devices such as a flow meter and a temperature sensor, valve devices such as a flow control valve and an on-off valve, actuator devices such as a fan and a motor, and other devices installed on the plant or factory site. is there. The operations of these field devices 1a to 1c are controlled based on control data transmitted from the device management apparatus 2 via the communication bus B. In addition, measurement data obtained by the field devices 1a to 1c are collected by the device management apparatus 2 via the communication bus B.

  The communication bus B is a wired communication bus laid in a plant or the like, and connects the field devices 1a to 1c installed in a site such as a plant and the device management apparatus 2 installed in a management room such as a plant. To do. As this communication bus B, for example, a Foundation Fieldbus (registered trademark), HART (Highway Addressable Remote Transducer: registered trademark), Profibus (PROFIBUS: registered trademark), or a serial communication bus defined by BRAIN, etc. Can be used.

  The device management apparatus 2 manages and controls the field devices 1a to 1c while exchanging various parameters with the field devices 1a to 1c via the communication bus B. For example, the parameters set in the field devices 1a to 1c are acquired to grasp the current measurement conditions, and the measurement parameters are changed by setting new parameters in the field devices 1a to 1c. The device management apparatus 2 is operated by an administrator (an administrator of the device management system MS).

  The device management apparatus 2 is realized by, for example, a notebook or desktop personal computer including an input device 2a such as a keyboard, a display device 2b such as a liquid crystal display device, and a drive device 2c. The drive device 2c is a device that reads data recorded on a computer-readable recording medium M such as a CD-ROM or a DVD (registered trademark) -ROM. The functions of the device management apparatus 2 (functions for managing and controlling the field devices 1a to 1c) are realized by software by reading and installing the program recorded in the recording medium M by the drive device 2c.

  FIG. 2 is a functional block diagram showing main functions implemented by the device management apparatus according to the embodiment of the present invention. As shown in FIG. 2, in the device management apparatus 2, a management control unit 10 (management control means), a DTM control unit 20, and DTMs 30a to 30c (operation means) are realized. The functions shown in FIG. 2 are realized by executing a program read from the recording medium M shown in FIG. 1 and installed in accordance with an instruction from the administrator.

  The management control unit 10 performs overall management and control of the field devices 1a to 1c. Specifically, various information (device information, repair history information) and the like related to the field devices 1a to 1c are made into a database and managed in an integrated manner. Further, a window screen (main screen W1 shown in FIG. 4) that can be operated by the administrator is displayed on the display device 2b (see FIG. 1), and various information related to the field devices 1a to 1c is displayed via the window screen. And the field devices 1a to 1c are controlled in accordance with an operation instruction from the administrator for the window screen. Furthermore, the state monitoring and diagnosis of the field devices 1a to 1c connected to the communication bus B are performed online.

  The DTM control unit 20 includes a parameter setting unit 21 (setting instruction unit) and a virtual DTM 22 (execution control unit). The DTM control unit 20 controls the DTMs 30a to 30c based on an instruction from the management control unit 10, and An operation corresponding to the instruction is performed on the field devices 1a to 1c. Here, the operations performed on the field devices 1a to 1c include, for example, acquisition of parameters from the field devices 1a to 1c, setting of new parameters for the field devices 1a to 1c, and the above-described online field devices 1a to 1c. Status monitoring and diagnosis. The DTM control unit 20 is created in conformity with FDT.

  The parameter setting unit 21 instructs parameter setting for the field device designated by the management control unit 10 among the field devices 1a to 1c connected to the communication bus B. The parameter setting unit 21 may instruct to set parameters individually for each field device 1a to 1c, or may instruct to set parameters (common parameters) common to the field devices 1a to 1c. Is possible.

  Specifically, the parameter setting unit 21 includes a parameter acquisition unit 21a (acquisition unit) and a common parameter extraction unit 21b (extraction unit). The parameter acquisition unit 21 a instructs the virtual DTM 22 to acquire parameters used in the field device specified by the management control unit 10. Here, when a plurality of field devices are designated by the management control unit 10, the virtual DTM 22 is instructed that parameters should be acquired from all designated field devices.

  The common parameter extraction unit 21b extracts common parameters common to the field devices specified by the management control unit 10 from the parameters acquired by the parameter acquisition unit 21a. Here, the common parameter extraction unit 21b extracts a parameter of the same type or a parameter of the same type and value as a common parameter from the parameters acquired by the parameter acquisition unit 21a. Note that the parameter setting unit 21 indicates which of the above parameters is to be extracted as a common parameter.

  The above parameter setting unit 21 displays a window screen (for example, the common parameter setting screen W2 shown in FIG. 5) that can be operated by the administrator on the display device 2b, and displays the field devices 1a to 1c connected to the communication bus B. Along with the information shown, the common parameters extracted by the common parameter extraction unit 21b are displayed in the window screen in a manner that can be changed by the administrator. Further, the parameter setting unit 21 virtually issues an instruction to set the setting of the common parameter displayed on the window screen when the administrator gives an instruction to set the common parameter to the window screen. Perform for DTM22.

  The virtual DTM 22 controls the DTMs 30 a to 30 c based on an instruction from the parameter setting unit 21 and executes operations on the field devices 1 a to 1 c according to the instruction from the parameter setting unit 21. For example, when the parameter setting unit 21 gives an instruction to acquire parameters of the field devices 1a to 1c, the DTMs 30a to 30c are sequentially controlled to acquire parameters from the field devices 1a to 1c. When the parameter setting unit 21 instructs the field devices 1a to 1c to set common parameters, the DTMs 30a to 30c are sequentially controlled to set the common parameters to the field devices 1a to 1c. Let it be set.

  The virtual DTM 22 enables the parameter setting unit 21 to handle the DTMs 30a to 30c as one virtual DTM by collectively controlling the DTMs 30a to 30c provided for the field devices 1a to 1c. It is. By enabling such handling, there is no need to start frame applications for exchanging information with the DTM separately (separate processes) as in the prior art.

  The DTMs 30a to 30c are provided for the field devices 1a to 1c, respectively, and perform operations on the field devices 1a to 1c according to instructions from the management control unit 10 under the control of the DTM control unit 20, respectively. Specifically, the DTMs 30a to 30c acquire parameters from the field devices 1a to 1c, set new parameters for the field devices 1a to 1c, and monitor the state of the field devices 1a to 1c under the control of the DTM control unit 20. And diagnosis etc. are performed individually.

  Next, the operation of the device management apparatus 2 having the above configuration will be described. FIG. 3 is a flowchart showing an operation at the time of parameter setting of the device management apparatus according to the embodiment of the present invention. 4 is displayed on the display device 2b by the management control unit 10 in the state in which the power of the device management apparatus 2 is turned on, and the field devices 1a to 1c connected to the communication bus B are related to the main screen W1. Various types of information are displayed on the main screen W1.

  FIG. 4 is a diagram illustrating an example of a main screen displayed on the device management apparatus according to the embodiment of the present invention. A main screen W1 illustrated in FIG. 4 includes a protocol display area R1 and a device display area R2. The protocol display area R1 is an area where a list of communication protocols that can be used by the field devices 1a to 1c connected to the communication bus B is displayed. The device display area R2 is an area in which field devices that can use the communication protocol selected by the administrator's operation among the communication protocols listed in the protocol display area R1 are displayed in a list. In the device display area R2 of the main screen W1 shown in FIG. 4, “EJX (registered trademark) 110A”, “EJX110B”, and “EJX110B”, which are names of the field devices 1a, 1b, and 1c, are displayed.

  Now, in a state where the main screen W1 shown in FIG. 4 is displayed on the display device 2b, the administrator performs an operation of selecting the field device displayed in the device display area R2 of the main screen W1 by the input device 2a. Suppose. Then, the field device corresponding to the operation of the administrator is selected by the management control unit 10 as the field device for changing the parameter (step S11). Here, the administrator performs an operation of selecting all of “EJX110A”, “EJX110B”, and “EJX110B” displayed in the device display area R2, and all of the field devices 1a to 1c shown in FIG. It is assumed that the management control unit 10 selects the field device for changing the parameter.

  When a field device whose parameter is to be changed is selected, information indicating the selected field device is output from the management control unit 10 to the parameter setting unit 21. Specifically, the device ID uniquely assigned to each of the field devices 1a to 1c, the device type and device revision indicating the type and modification number of the field devices 1a to 1c, and the communication usable in the field devices 1a to 1c. Information indicating the protocol is output from the management control unit 10 to the parameter setting unit 21 as information indicating the selected field device.

  When information from the management control unit 10 is input to the parameter setting unit 21, the parameter acquisition unit 21a instructs the virtual DTM 22 to acquire parameters, and the field device (field devices 1a to 1a) selected by the management control unit 10 is instructed. A process of acquiring the parameter information 1c) is performed (step S12). Specifically, when a parameter acquisition instruction is issued from the parameter acquisition unit 21a to the virtual DTM 22, the virtual DTM 22 first controls the DTM 30a to perform an operation of acquiring parameters used in the field device 1a. Next, the virtual DTM 22 controls the DTM 30b to perform an operation of acquiring parameters used in the field device 1b, and then controls the DTM 30c to perform an operation of acquiring parameters used in the field device 1c. The parameters acquired by the control of the virtual DTM 22 are transferred from the virtual DTM 22 to the parameter setting unit 21 and acquired by the parameter acquisition unit 21a.

  When the parameter acquisition is completed, the common parameter extraction unit 21b performs a process of extracting the common parameter from the acquired parameter (step S13). Specifically, a process of extracting a parameter having the same type and value as a common parameter from parameters acquired from the field devices 1a to 1c based on an instruction from the parameter setting unit 21 is performed. For example, it is assumed that the field devices 1a to 1c are thermometers and parameters indicating the upper limit value of the temperature measurement range are acquired from all the field devices 1a to 1c. In such a case, if the values (set values) of these parameters are all the same, the parameters are extracted as common parameters, but if there are even ones having different values, they are not extracted as common parameters.

  When the common parameter extraction process is completed, the parameter setting unit 21 displays the common parameter setting screen W2 shown in FIG. 5 on the display device 2b, and the extracted common parameters are displayed (step S14). FIG. 5 is a diagram showing an example of a common parameter setting screen displayed on the device management apparatus according to the embodiment of the present invention. The common parameter setting screen W2 illustrated in FIG. 5 includes a selected device display area R11, a common parameter display area R12, and an apply button BT1.

  The selected device display area R11 is an area where a list of field devices selected on the main screen W1 shown in FIG. 4 is displayed. The common parameter display area R12 is an area where the common parameters extracted by the common parameter extraction unit 21b are displayed. The apply button BT1 is a button for instructing the field device displayed in the selected device display area R11 on the common parameter setting screen W2 to set the common parameter displayed in the common parameter display area R12. It is.

  In the selected device display area R11 shown in FIG. 5, “EJX110A”, “EJX110B”, and “EJX110B” which are names of the field devices 1a, 1b, and 1c selected on the main screen W1 shown in FIG. 4 are displayed. . The common parameter display area R12 shown in FIG. 5 includes a parameter indicating a temperature unit (Unit), a parameter indicating an upper limit value of the temperature measurement range (Upper RANGE), and a lower limit value of the temperature measurement range (Lower RANGE). ) Is displayed as a common parameter.

  Here, the value of the common parameter is displayed on the common parameter setting screen W2 in a changeable manner. That is, the values of the common parameters are displayed in the input boxes BX1 to BX3. If the administrator performs an operation for changing the values of the input boxes BX1 to BX3, the values of the common parameters can be changed. Here, for simplicity of explanation, the case where only the extracted common parameters are displayed will be described as an example, but the parameters other than the common parameters among the parameters acquired from the field devices 1a to 1c are described. The parameters may be collectively displayed on another parameter display screen.

  When the common parameter setting screen W2 shown in FIG. 5 is displayed on the display device 2b, whether or not the application button BT1 provided on the common parameter setting screen W2 is pressed (whether or not there is a common parameter setting instruction) is determined by the parameter setting unit. 21 (step S15). If it is determined that the application button BT1 is not pressed (when the determination result is “NO”), the determination in step S15 is repeated. Note that while the determination in step S15 is repeated, the administrator can change the values of the input boxes BX1 to BX3 by operating the input device 2a.

  On the other hand, when it is determined that the apply button BT1 is pressed (when the determination result of step S15 is “YES”), a new one is added to the field devices 1a to 1c selected on the main screen W1 shown in FIG. A process for sequentially setting common parameters is performed (step S16). Specifically, first, the parameter setting unit 21 provides the virtual DTM 22 to the field device displayed in the selected device display area R11 of the common parameter setting screen W2 shown in FIG. An instruction is given to set the values of the parameters input in the input boxes BX1 to BX3.

  When such an instruction is given, the virtual DTM 22 first controls the DTM 30a to cause the field device 1a to perform an operation for setting a new common parameter. Next, the virtual DTM 22 controls the DTM 30b to cause the field device 1b to perform a new common parameter operation, and then controls the DTM 30c to cause the field device 1c to set a new common parameter. Let the operation be performed. Thus, the setting of common parameters for the field devices 1a to 1c is completed.

  As described above, in the present embodiment, the parameter setting unit 21 that instructs the field device selected on the main screen W1 displayed by the management control unit 10 to set the common parameter, and the field based on the instruction of the parameter setting unit 21 A virtual DTM 22 that controls the DTMs 30a to 30c provided for each of the devices 1a to 1c and sequentially executes setting of common parameters for the field devices selected on the main screen W1 is provided. For this reason, the administrator performs an operation of selecting a field device for setting a common parameter on the main screen W1, and inputs a common parameter to be set and an instruction for setting the same on the common parameter setting screen W2. The parameters common to all (common parameters) can be set collectively. Thereby, since the frequency | count of the operation | work which sets a parameter reduces, a manager's operation mistake can be decreased and the stability and efficiency of a plant etc. can be aimed at as a result.

  In the above embodiment, the parameters used in the field device selected on the main screen W1 are acquired and common parameters are extracted. In this way, even when the common parameters are completely different for each combination of field devices selected on the main screen W1, the common parameters are automatically obtained, so that the common parameters can be set for a short time. And it can be done easily.

  Next, a modified example of the common parameter setting screen displayed on the device management apparatus 2 will be described. FIG. 6 is a diagram showing a first modification of the common parameter setting screen displayed on the device management apparatus according to the embodiment of the present invention. Although the common parameter setting screen W2 shown in FIG. 5 is a screen for collectively setting common parameters having the same value for the selected field device, the common parameter setting screen W3 shown in FIG. This is a screen that allows setting common parameters with different values for each device.

  The common parameter setting screen W3 illustrated in FIG. 6 includes a selected device display area R21, a common parameter display area R22, and an apply button BT2. Similar to the selected device display area R11 shown in FIG. 5, the selected device display area R21 is an area in which the field devices selected on the main screen W1 shown in FIG. 4 are displayed as a list. The difference is that it can be selected by the operation of the administrator.

  Similar to the common parameter display region R12 shown in FIG. 5, the common parameter display region R22 is a region where the common parameters extracted by the common parameter extraction unit 21b are displayed, but the field selected in the selected device display region R21. The difference is that common parameters for devices are displayed. In this common parameter display area R22, the name N of the field device is displayed in order to determine which field device the common parameter is displayed on.

  The apply button BT2 is a button for instructing the field device selected in the selected device display area R21 on the common parameter setting screen W3 to set the common parameter displayed in the common parameter display area R22. That is, the apply button BT2 is a button for instructing the field device selected in the selected device display area R21 on the common parameter setting screen W3 to individually set parameters. Immediately after the common parameter setting screen W3 shown in FIG. 6 is displayed on the display device 2b, the display of the common parameter display region R22 is possible regardless of which field device listed in the selected device display region R21 is selected. The contents are the same except for the name N.

  While the common parameter setting screen W3 shown in FIG. 6 is displayed on the display device 2b, the administrator operates the input device 2a to select one of the field devices listed in the selected device display area R21. Then, the common parameter for the selected field device is displayed in the common parameter display area R22. Here, when the administrator performs an operation of changing the value of the common parameter displayed in the common parameter display region R22 and pressing the apply button BT2, the parameter setting unit 21 and the virtual DTM 22 cause the selected device display region R21 to be displayed. A new parameter is set only for the selected field device.

  Next, when the administrator operates the input device 2a and selects a different field device in the selected device display area R21, common parameters for the selected field device are displayed in the common parameter display area R22. When the administrator changes the value of the common parameter displayed in the common parameter display area R22 and presses the apply button BT2, the field device newly selected by the parameter setting unit 21 and the virtual DTM 22 is selected. A new parameter is set only for. Thus, on the common parameter setting screen W3, it is possible to set different values for each field device for the extracted common parameters.

  FIG. 7 is a diagram showing a second modification of the common parameter setting screen displayed on the device management apparatus according to the embodiment of the present invention. The common parameter setting screens W2 and W3 shown in FIG. 5 and FIG. 6 are screens on which only common parameters can be set. However, the common parameter setting screen W4 shown in FIG. This is a screen that enables the setting of parameters (hereinafter referred to as individual parameters).

  The common parameter setting screen W4 illustrated in FIG. 7 includes a selected device display area R31, a parameter display area R32, and an apply button BT3. The selected device display area R31 is an area in which a list of field devices selected on the main screen W1 shown in FIG. 4 is displayed in the same manner as the selected device display area R11 shown in FIG. The parameter display area R32 is an area where common parameters or individual parameters are displayed.

  The parameter display area R32 includes tabs T1 for displaying common parameters common to the field devices listed in the selected device display area R31, and tabs T11 to T13 for displaying individual parameters for each field device. Yes. The number of tabs T11 to T13 increases or decreases according to the number of field devices displayed in a list in the selected device display area R31. The apply button BT3 is a button for giving an instruction to set a common parameter or an individual parameter displayed in the parameter display area R32 of the common parameter setting screen W4.

  When the administrator operates the input device 2a and selects the tab T1 provided in the parameter display region R32 while the common parameter setting screen W4 shown in FIG. 7 is displayed on the display device 2b, the selected device display region R31. The common parameters common to the field devices listed in the above are displayed in the parameter display area R32. Here, when the administrator performs an operation of changing the value of the common parameter displayed in the parameter display area R32 and pressing the apply button BT3, the list is displayed in the selected device display area R31 by the parameter setting unit 21 and the virtual DTM22. Batch setting of new common parameters is performed for the displayed field devices

  On the other hand, when the administrator operates the input device 2a to select any of the tabs T11 to T13 provided in the parameter display area R32, the individual parameters of the field device are displayed in the parameter display area R32. Here, when the administrator performs an operation of changing the value of the individual parameter displayed in the parameter display area R32 and pressing the apply button BT3, the field corresponding to the selected tab is displayed by the parameter setting unit 21 and the virtual DTM 22. A new individual parameter is set only for the device.

  The device management apparatus and the recording medium according to the embodiment of the present invention have been described above, but the present invention is not limited to the above-described embodiment, and can be freely changed within the scope of the present invention. For example, in the above embodiment, the device management apparatus 2 that controls the field devices 1a to 1c that perform communication via the wired communication bus B has been described as an example. However, the present invention can also be applied to a device management apparatus that manages and controls field devices (wireless field devices) that communicate via a wireless network.

  In the above-described embodiment, the device management apparatus using the FDT / DTM technology has been described as an example, but the present invention can also be applied to a device management apparatus using the EDDL technology. Moreover, although the example which extracts the parameter with the same kind and value as a common parameter was demonstrated in the said embodiment, you may extract the parameter with only the same kind as a common parameter.

  In the above embodiment, the case where the function of the device management apparatus 2 is realized by software by reading and installing the program recorded in the recording medium M by the drive apparatus 2c has been described as an example. However, the computer may be connected to a network such as the Internet so that a program similar to the program recorded on the recording medium M can be downloaded from the network to the computer. The program downloaded to the computer can be installed in the computer in the same manner as when reading from the computer-readable recording medium M using the drive device 2c. Note that the function of the device management apparatus 2 can also be realized by hardware.
