Description

  The present invention relates to a parameter setting device and a parameter setting method.

At the site where the production process is managed, various devices (for example, sensors and valves) having a communication function are installed in the plant. Then, various production processes are managed by connecting the device to a network called a field bus and capturing a signal transmitted from the device into the system. Fieldbus is a communication network that enables two-way communication using digital signals, and its communication specifications are standardized (standardized) as Foundation Fieldbus by the Fieldbus Foundation ^TM. Yes.

  Devices used in the fieldbus are multi-vendors, and each vendor uniquely sets parameters to be set in the devices and values of the parameters. Therefore, when the device is used in the field system, it is necessary to change the setting of each device in accordance with the specification of the system. In such a change, since the same setting is repeatedly performed for each device, the number of man-hours required for the work increases and the possibility of causing a setting error increases. Japanese Patent Application Laid-Open Publication No. 2004-228561 discloses a technique for setting the same setting information for a plurality of devices.

JP 2010-181930 A

  By the way, even when the device is used in the same system, it is necessary to change the setting according to the usage mode such as the location and the role. Therefore, simply setting the same setting information uniformly for a plurality of devices as in the technique described in Patent Document 1 above does not solve the problem of work man-hours and setting errors. .

  The present invention has been made to solve the above-described problems caused by the prior art, and provides a parameter setting device and a parameter setting method capable of reducing the number of work steps during parameter setting and preventing setting errors. For the purpose.

  The parameter setting device according to the present invention includes, for each device, at least a first template that defines a default value of a parameter corresponding to the model of the device and a second template that defines a default value of a parameter corresponding to the use of the device. A registration unit for registering the template, a determination unit for determining the device to be set as a parameter, the first template and the second template registered corresponding to the determined device A writing unit that writes a default value of a parameter defined in any of the above to a parameter corresponding to the determined device.

  The parameter setting method according to the present invention defines, for each device, at least a first template that defines default values of parameters corresponding to the device model and default values of parameters corresponding to the use of the device. A registration step of registering a second template; a determination step of determining the device to be set with a parameter; the first template and the second registered corresponding to the determined device; Writing a default value of a parameter defined in any of the templates to a parameter corresponding to the determined device.

  By adopting such a configuration, at least the first template that defines the default value of the parameter according to the device model and the second template that defines the default value of the parameter according to the application of the device are provided for each device. When setting a parameter of a device, a default value of a parameter defined in any template corresponding to the device can be written in the parameter of the device. Therefore, the parameter can be set based on the default value of the parameter that is optimal for the device.

  The first template may be defined for each version provided for the device model, and the second template may be defined for each use of the device.

  As a result, a template corresponding to the device version or device application can be prepared, and the parameters can be set based on the optimum default value corresponding to the version and application.

  Further, the first template and the second template are registered so as to be identifiable according to a usage mode of the device, and the writing unit is registered corresponding to the determined device. A default value of a parameter defined in a template corresponding to the usage mode selected and instructed by a user among the first template and the second template is written in the parameter corresponding to the determined device. It is good as well.

  Accordingly, it is possible to acquire a default value that is optimal for the device to be set by selecting the usage mode of the device.

  ADVANTAGE OF THE INVENTION According to this invention, the parameter setting apparatus which can reduce the work man-hour at the time of parameter setting and can prevent a setting mistake can be provided.

It is a figure which illustrates the structure of the device management system containing the parameter setting apparatus in embodiment. It is a conceptual diagram of the data stored in template DB of FIG. It is a conceptual diagram of the data stored in parameter DB of FIG.

  Embodiments according to the present invention will be described below with reference to the drawings. However, the embodiment described below is merely an example, and does not exclude application of various modifications and techniques not explicitly described below. That is, the present invention can be implemented with various modifications without departing from the spirit of the present invention.

  FIG. 1 is a diagram showing a schematic configuration of a device management system including a parameter setting device according to an embodiment of the present invention. As illustrated in FIG. 1, the device management system 100 includes a parameter setting device 1, a controller 2, and devices 3A to 3P. The controller 2 and the devices 3A to 3P are connected to the field bus F, and can communicate with each other. The fieldbus F is a network that uses the above-described foundation fieldbus protocol as a communication specification. Note that the devices 3A to 3P are referred to as devices 3 when there is no need to distinguish them in the following description.

  The device 3 is various devices installed in the plant, and has a function of performing bidirectional communication via the field bus F. Examples of the device 3 include various sensors such as a flow sensor, a pressure sensor and a temperature sensor, various valves such as a flow control valve and a pressure control valve, and various actuators such as a pump and a fan.

  The controller 2 is a control device that monitors and controls the device 3, and relay-controls, for example, parameter setting processing performed between the parameter setting device 1 and the device 3. The controller 2 has a function of controlling the execution state of the production process when executing the production process. Specifically, for example, the controller 2 controls the device 3 that is a valve based on measured values such as a flow rate and pressure acquired from the device 3 that is a sensor, so that the opening degree of a valve provided in the pipe, etc. Adjust.

  The parameter setting device 1 is a device that sets parameters of the device 3. The parameter setting device 1 physically includes, for example, a CPU (not shown), a storage device (not shown) such as a memory, and an input / output interface (not shown). The storage device stores templates, parameters, device information, job information, and the like, which will be described later. The input / output interface is an interface that transmits / receives data to / from an input device such as a keyboard and a mouse and an output device such as a display and a printer.

  Functionally, the parameter setting device 1 includes, for example, a template registration unit 11, a target determination unit 12, and a parameter writing unit 13.

  The template registration unit 11 registers (exports) a template that defines parameters used by the device 3 and default values of the parameters in the template DB 14.

  A template registered in the template DB 14 will be described with reference to FIG. As shown in FIG. 2, there are two types of templates registered in the template DB 14. One is a system template defined for each model of the device 3, and the other is a job template defined for each use (job) of the device 3. That is, one or more system templates can be specified for one device 3, and one or more job templates can be specified for one device 3. When a plurality of versions are provided for the device 3 model, one system template is defined for each version.

  The template will be specifically described. For example, the model of the device 3 is “temperature sensor A”, and “temperature sensor A” is used in two applications: “measurement range is 0 to 100 ° C.” and “measurement range is 0 to 150 ° C.”. If there is one, the following three templates are registered in the template DB 14. (1) System template for “temperature sensor A”, (2) Job template for “temperature sensor A” and “measurement range is 0 to 100 ° C.”, (3) “temperature sensor A” and “measurement range is 0” Job template for "~ 150 ° C".

  Examples of the parameter include a parameter for setting a normal value or abnormal value range, a standby time for determining transition to a warning state, and the like.

  The parameters specified in the system template and the default values of the parameters are determined by the system vendor side and cannot be changed by the user side. On the other hand, the parameters defined in the job template and the default values of the parameters can be determined and changed by the user. The job template can be arbitrarily defined for each job, that is, for each use of the device 3.

  The target determination unit 12 illustrated in FIG. 1 determines a device 3 that is a parameter setting target. Specifically, for example, when the device information of the device 3 to be used in the system is defined or when the device 3 to be used in the job is defined in the job information, the target determining unit 12 is configured to apply a specific device to the user. When selected as a setting target, the definition or selected device 3 is determined as a parameter setting target. The device information is information about the device, and includes, for example, a device ID that uniquely identifies the device. The job information is information related to the job, and includes, for example, a job ID that uniquely identifies the job.

  As a method for the user to select a specific device, for example, the job ID and the device ID used in the job are displayed on the screen in a tree structure with each job ID as a root, and displayed below the job ID. It is possible to use a method that allows the user to arbitrarily select from the device IDs.

  The parameter writing unit 13 writes the parameter to be set for the device to be set determined by the target determining unit 12 in the parameter DB 15. With reference to FIG. 3, the parameter written in parameter DB15 is demonstrated. As shown in FIG. 3, the parameters written in the parameter DB 15 are stored so that each device 3 can be uniquely identified.

  For example, the parameter writing unit 13 writes the parameter of the device to be set in the parameter DB 15 by the following procedure. Here, a procedure when the device 3 used in the job is defined in the job information will be described.

First, the parameter writing unit 13 selects a job template corresponding to the job in which the device to be set is defined from the job templates registered corresponding to the device to be set determined by the target determining unit 12 from the template DB1. Read from 4 (import).

  Subsequently, the parameter writing unit 13 displays the default values of the parameters defined in the read job template on the screen. The user can arbitrarily change the default value of each parameter displayed on the screen.

  Subsequently, when the writing instruction is given by the user, the parameter writing unit 13 sets a parameter with the parameter value displayed on the screen at that time as a set value as the parameter of the device to be set. Write to.

Since the above procedure is the procedure when the device to be set is defined in the job information, even if there are multiple job templates, the template that identifies the optimal job template for the device to be set based on the job it can be read from DB1 4.

However, when a job using the setting device can not be identified, it is difficult to read from the template DB1 4 to identify the best template on the device from the job template plurality of.

Therefore, when setting the parameters in case that can not be identified jobs using the setting device, to select the mode of use of the device to the user, even to read the template corresponding to the selected mode of use from the template DB1 4 Good. Examples of usage modes include “system-dependent use” in which a system template is an optimal template, “job-dependent use” in which a job template is an optimal template, and the like. When there are a plurality of job templates, the name of “job-dependent use” may be selected by the user so that the job or application can be identified.

  By allowing the user to select the usage mode, even if the user does not fully understand the role and setting contents of the parameter, the optimal parameter for the device 3 can be selected by selecting the usage mode of the device 3. It can be easily set.

  When one system template and one job template are registered for a certain device 3, the job template may be read preferentially.

  As described above, according to the parameter setting device 1 in the embodiment, one system template that defines the default value of the parameter according to the model (version) of the device 3 and the default value of the parameter according to the application of the device are set. One or more defined job templates can be registered in the template DB 14 for each device.

  Further, when setting the parameter of the device 3, the default value of the parameter defined in any of the templates corresponding to the device 3 can be written in the parameter of the device 3. Therefore, the parameter can be set based on the default value of the parameter optimum for the device 3.

  Therefore, according to the parameter setting device 1 in the embodiment, it is possible to reduce the man-hours for setting parameters and prevent setting errors.
