Description

  The present invention relates to a data creation device and method for creating data for identifying a target device such as a field device connected to a control system and a device management device.

  For example, a control system is used for monitoring control of each facility attached to a building and control of a plant and the like, and an equipment management device may be used (see Patent Document 1). For example, a device management device exchanges signals with field devices such as process devices and various sensors installed on the site connected via a network such as a field bus, and conventionally a portable terminal has been installed on the field device. The calibration, which is directly connected to, is performed with the parameter setting from the host, and the diagnosis result regarding the state in which the field device is operating normally is displayed.

  In such a control system or device management apparatus, for example, when the configuration of the control target is changed, engineering such as changing the control program set in the system or changing the field device configuration set in the device management apparatus. Work occurs. In the control described above, there are many control objects, and in engineering work, the target data is very large.

  At present, a digital signal is superimposed on an analog control signal, and “additional information” such as secondary measurement values (for example, temperature for pressure correction in a pressure gauge) of field devices and setting parameters of field devices is displayed. Network systems that transmit and receive data to and from control systems and equipment management devices have also been developed. This network system is called HART (Highway Addressable Remote Transducer; registered trademark) communication, and the use of devices conforming to the HART communication specification is increasing.

  Conventionally, in a control system, a current value such as 4-20 mA is used to indicate a sensor value or a control value of 0-100% in connection with a field device. On the other hand, in HART communication, a digital signal is superimposed on the analog control signal described above, for example, secondary measured values of field devices such as temperature for temperature / pressure correction in a pressure gauge, setting parameters of field devices, etc. “Additional information” can be transmitted and received between the two.

  Initially, field device parameter settings, such as range setting using a handheld terminal with HART communication specifications, were the main purpose. However, in recent years, the field device's Monitoring diagnostic information has also become one of the main objectives.

  In the above-described device management apparatus, device names that serve as identifiers (IDs) of measurement points in the sensors and operation points of the valve positioner are attached to the connected field devices, for example. This device name is used for identification of the field device by the user at the time of installation or maintenance of the field device. In the HART communication specification, a field device to be connected is set as a TAG parameter, and the device management apparatus side identifies each field device using the set TAG parameter.

  The device name (TAG parameter value) used in this way is configured with an upper limit of 8 characters in the version 5 HART communication specification mainly used at present. In the next-generation version 6 HART communication specification, the upper limit of the number of characters that can be used for the device tag is 32. However, the field devices of the version 5 HART communication specification are mainly used in the devices currently in use. .

  On the other hand, in the control system, for input from field devices such as sensors and output to field devices such as valve positioners, for each input and output, there are multiple values such as numerical values for conversion to industrial unit values and alarm alert thresholds. There is a data point with a set of parameters. A separate database is constructed for each data point, identification information (point name) is added to this database, and the operator of the control system uses it to identify measurement points and operation points.

  When viewed from the field device, one data point basically corresponds to one field device. For example, if the field device is a sensor, it is connected to the control system as an analog input (AI), and this AI is treated as one AI data point as seen from the control system. When the field device is a valve positioner, it is connected to the control system as an analog output (AO), and this AO is handled as one AO data point by the control system. Therefore, the “point name” of the data point used in the control system can be associated with the “device name” of the field device used in the device management apparatus.

  Using the above-mentioned relevance, the function to automatically generate a part of definition information for handling field devices in the device management device is used from the setting information of the data points of the control system to reduce the engineering work load. ing. Definition information for handling field devices in the device management apparatus includes controller information and I / O module information of field devices. In such automatic generation, the related point name is set as the initial value of the device name. Since point names are often close to or the same as measurement points and operation points, they are close to or the same as device names. By using this, field device information setting work in the device management device can be performed. Can be reduced.

  However, although the upper limit of the number of characters used is 16 characters for the point names used in the conventional control systems that are widely used at present, the version 5 HART communication specification in the device management apparatus currently used as the mainstream Then, the upper limit number of characters of the device name (TAG parameter) is 8. For this reason, if the point name is used as it is for the device name, the upper limit of the number of characters may occur, resulting in a setting error.

  The present invention has been made to solve the above-described problems, and for identifying a measurement point to which a connection target used in a control system is connected, an output point that is an output destination of a control result, and the like.

FIG. 4 is a configuration diagram illustrating a display example on the display unit 107.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a data creation device 100 according to an embodiment of the present invention. The data creation device 100 includes a point definition data storage unit 101, a device definition data storage unit 102, a device management data generation unit 103, and a conversion rule storage unit 104. A plurality of field devices (target devices) 112 are connected to the control system 113 via the network 121, and are connected to the device management apparatus 111 via the HART communication network 122. In addition, the device management apparatus 111 is connected to the data creation apparatus 100.

  Although omitted in FIG. 1, a plurality of field devices 112 are connected to the device management apparatus 111 and the control system 113 as shown in FIG. First, a plurality of controllers 114 are connected to the control system 113 via a network 121a, and a plurality of I / O modules 115 are connected to each controller 114. A plurality of field devices 112 are connected to each I / O module 115 via a network 121b. The I / O module 115 includes an I / O data point to which each input from the field device 112 such as a sensor and the opening output from the field device 112 such as a valve positioner are individually connected. Further, the controller 114 includes a functional block that controls, for example, PID.

  On the other hand, a signal converter 116 is connected to the device management apparatus 111 via a HART communication network 122a, and a plurality of field devices are connected to the signal converter 116 via a signal line 122b constituting a part of the HART communication network. Each of 205 is connected. Although omitted in FIG. 2, the signal line 122 b is provided for each field device 112.

  The point definition data storage unit 101 is connected to the field device 112 connected to the control system 113 via the network 121 (network 121a, network 121b) (connected measurement points, output points that are output destinations of control results, etc.) The point definition data indicating the connection state including the item of the point name (tag information in the control system) for identifying) is stored. For example, the point definition data storage unit 101 stores point definition data as shown in Table 1 below.

  In Table 1, “Type” indicates “I / O module type” of the I / O module 115 to which the corresponding point is internally connected. The “controller number” identifies the controller 114 to which it belongs, the “IOM (I / O module) number” identifies the I / O module 115 to be connected, and the “slot number” is within the I / O module 115. This indicates the number of the software slot in which the point is defined, and has a one-to-one correspondence with the terminal group number (plus terminal and minus terminal) to which the device is connected in the I / O module. “Industrial unit”, “PV (process value) upper limit range”, and “PV lower limit range” are display / processing information at the point to which the field device 112 is connected.

  The device definition data storage unit 102 includes an item of a device name (device tag information) of the field device 112, and is used to define the field device 112 in the device management apparatus 111 connected to the field device 112 via the HART communication network 122. The device definition data is stored. The device definition data stored in the device definition data storage unit 102 is used by the device management apparatus 111. For example, the device definition data storage unit 102 stores device definition data as shown in Table 2 below.

  In the following example, “device name” which is an item of device tag information for identifying the field device 112 in the device management apparatus 111, “vendor” which is an item for identifying the manufacturer of the field device 112, and the type of the field device 112 are specified. “Device type” which is an item to be used, and “HART version” which is an item indicating the version of HART communication to be used. In addition, “point name”, “controller number”, “IOM number”, “slot number” and the like used on the control system 113 side are also provided.

  The device management data generation unit 103 converts the point name according to the set conversion rule and generates a device name. The conversion rule is stored in the conversion rule storage unit 104. For example, in the example shown in Table 2, the device name “FI0001A” is generated by removing “_” from the point name “FI_0001_A”. In this case, the conversion rule is “removes _ from the text data constituting the point name”.

  In addition, the device management data generation unit 103 generates device definition data by extracting common items from the point definition data stored in the point definition data storage unit 101, and, for example, according to an instruction input from the user. , “Device name”, “vendor”, “device type”, “HART version”, and the like are added.

  In addition, the data creation device 100 includes a conversion rule definition unit 105 that receives an input of a conversion rule and stores it in the conversion rule storage unit 104. The data creation apparatus 100 also includes a display control unit 106 that controls generation and display of display data for inputting conversion rules, and a display unit 107 that displays display data generated by the display control unit 106.

  Next, the operation (data creation method) of the data creation device in the embodiment of the present invention will be described using the flowchart of FIG. First, in step S101, point definition data indicating a connection state including an item of a point name (tag information in the control system) of the field device 112 is stored.

  Next, in step S102, the setting of the conversion rule is started by a user instruction input (y in step S102). In step S103, the display control unit 106 generates and displays display data for inputting the conversion rule. Is displayed on the display unit 107 in step S104.

  For example, as shown in FIG. 4, a dialog box 171 that prompts input of conversion rules is displayed on the display unit 107. The dialog box 171 displays a check box by “◯”, buttons such as “OK” and “Cancel”, and a text box in which text (characters) can be input.

  Conversion rules include “use point name as is”, “delete next character”, “change next character”, and the like. “Erase next character” erases the designated character entered in the text box from the point name and sets it as the device name. For example, if it is considered that there is no problem in excluding “_” in the point name in the format of “FI — 0001_A”, “_” is entered in the text box. When this conversion rule is used, “FI — 0001_A” is converted to “FI0001A” and becomes the device name.

  In such a dialog box 171, when a check box is designated, a character is entered in the text box, and the “OK” button is selected (y in step S <b> 105), in step S <b> 106, the conversion rule definition unit 105 The specified conversion rule condition is stored in the conversion rule storage unit 104. When all the inputs are completed (y in step S107), in step S108, the device management data generation unit 103 follows the conversion rule stored (set) in the conversion rule storage unit 104 (point in control system tag). Information) is converted to generate a device name (device tag information), and device definition data is generated. In step S109, the generated device definition data is stored in the device definition data storage unit 102. The device definition data stored in the device definition data storage unit 102 in this way is used by the device management apparatus 111.

  The conversion rule may be set in advance in the conversion rule storage unit 104. In this case, the conversion rule may not be set according to a user instruction (step S102: n), and the process may proceed to step S108.

  As described above, according to the present invention, the tag information (point name) in the control system in the point definition data used in the control system is converted according to the set conversion rule, and the device management apparatus Since the device tag information of the device definition data used in is generated, device tag information (device name) can be automatically generated using the tag information in the control system without causing an error.

  The present invention is not limited to the embodiment described above, and many modifications and combinations can be implemented by those having ordinary knowledge in the art within the technical idea of the present invention. It is obvious. For example, in the above description, deletion or change of set character information is used as conversion information. However, a character string operation function or the like may be prepared so that more complicated conversion rules can be defined.
