Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control equipment management apparatus for centrally managing information on operation of control equipment such as setting of control parameters for control equipment and operation data obtained from the control equipment. is there.

[0002]

2. Description of the Related Art Motors have been developed in various fields, and various types of motors have been developed according to purposes and applications. For this reason, in order to control the motor, a control method according to its function, characteristics, application, and the like is required. Therefore, various methods have been tried for motor control.

For example, in recent years, advanced motor control using an inverter or the like, which has advantages such as high performance, high efficiency, and ease of use, has become widespread in various fields. The inverter rectifies and smoothes the commercial power, converts the commercial power to DC once, and then converts it to an arbitrary AC again. Therefore, the inverter can freely change the speed and change the frequency. For example, in a production site, positioning control requires fine speed control such as moving the work at high speed when the work is far from the target position, and moving the work at low speed as the work approaches the target position. Therefore, the motor control by the inverter is effective.

In the inverter as described above, not only the rotation speed and frequency but also various parameters (control constants) such as torque and position control can be set according to the function of the inverter. The setting of parameters is generally performed by key operation on the operation panel, but can be performed by a personal computer using software. Regarding parameter setting using software, for example, a program that allows a user to set a desired parameter is developed, or an application program for parameter setting is generally used.

[0005] Parameter setting by key operation is performed by an operation method such as directly inputting a numerical value with a numeric keypad or adjusting a numerical value with an up / down key, so that an operator at a production site can easily change the parameter. Can be. When a program developed by a user is used, parameter setting can be performed efficiently by using a program created so that a user can set desired parameters to be used. Further, when using an application program, a GUI (Graph
An environment is provided in which various parameter settings can be easily performed using a user interface such as the ical user interface), so that parameter settings can be performed efficiently as in the case of using the above user program. it can. Some application programs have a function of displaying the operation state of the inverter on a display. With such a function, information such as an operation frequency, a current, a voltage, and an alarm can be monitored.

[0006]

However, in parameter setting and monitoring by software, usually,
Since setting and monitoring work is performed on a personal computer that cannot cope with high temperatures and other environments at the production site,
At a production site or the like where such a computer cannot be brought in, a computer cannot be permanently installed for parameter setting and monitoring.

The present invention has been made in view of the above circumstances, and provides a control device management device capable of managing information of control devices such as an inverter even in a severe environment such as a production site. It is intended to be.

[0008]

In order to solve the above-mentioned problems, a control equipment management apparatus according to the present invention is a control equipment management apparatus for managing information relating to the operation of a control equipment such as an inverter. A display unit having a display surface for displaying, an input unit for inputting the setting of the information on the display surface, and at least one of the information input from the input unit or the information obtained from the control device Are displayed in a screen displayed on the display surface, and screen switching means for switching the display of the plurality of screens associated with each other.

In the above configuration, information is input by input means such as a touch panel on the display surface of the display means for displaying information. Therefore, a display device having a control function for FA (Factory Automation) such as a programmable display device or a panel computer can be suitably used as the control device management device. Further, since the input of information is performed by the input means as described above, an input device such as a mouse cannot be used unlike the input by a personal computer. For this reason, by displaying the input information in the screen displayed by the display control means, it is possible to input and display the information on the screen. Further, since the related screen is switched by the screen switching means, a desired screen can be easily called, and information setting and display can be performed smoothly.

[0010] In the control device management apparatus, it is preferable that the display control means displays a screen for setting a model of the control device on the top screen. When using multiple control devices of different models, enter information such as parameters for each control device (setting)
First, it is necessary to specify the model setting of the control device. On the other hand, by displaying the screen for setting the model of the control device on the top screen, it is possible to prompt the user to set the model first, and to prevent forgetting to set the model. .

[0011] The control device management apparatus may include storage means for storing a parameter read from the control device when a parameter defining a control function of the control device is set as the information. preferable. When setting parameters, an operation is usually performed in which parameters stored in the control device are read out, the values are changed, and then written to the control device. Therefore, it takes time to communicate with the control device when reading from and writing to the control device while setting the parameters one by one, thereby reducing the work efficiency. On the other hand, by storing the parameters previously read from the control device in the storage means as described above, it is not necessary to communicate with the control device when setting the parameters.

It is preferable that the control device management device further includes a storage unit that stores a parameter defining a control function of the control device as the information. By doing so, the parameters can be stored as required by the storage means, and the backup of the parameters is facilitated.

Further, the storage means stores the parameters in the memory card, so that a driver having no mechanical part can be mounted on the control device management apparatus.

In the above control device management apparatus, it is preferable that the storage means copies the parameters between different recording media. Thereby, for example, the parameters are copied between recording media such as a memory provided in the control device management device, the above-mentioned memory card, and a memory in the control device. It is also possible to copy the parameters of the control device of one station stored in the memory of another station to the memory of the control device of another station.

The test operation screen 46 displays the station number and the model name set as described above, and also displays the current frequency, current, and voltage.

The auto-tuning screen 47 is configured to automatically set the motor constant. For this reason,
The auto tuning screen 47, as shown in FIG.
It has a setting confirmation unit 47a, a forward switch 47b, a reverse switch 47c, and a return switch 47d.

When the user touches the setting confirmation section 47a, the screen shown in FIG.
The setting confirmation execution window 111 shown in FIG. When the user touches the setting confirmation switch 111a in the setting confirmation execution window 111, the above-described parameter setting screen 34 is displayed. Here, confirmation or input of the parmella is performed. Here, the parameter number corresponding to the auto tuning, for example, the parameter number (P
r. ) Confirmation or input is made for 71, 80, 83, 84 and 96. When this operation ends, the display returns to the auto tuning screen 47. When the cancel switch 111b is touched, the setting confirmation execution window 111 closes.

When the confirmation or input of the above-mentioned parameters is completed, if the forward rotation switch 47b is touched, the automatic tuning starts by forward rotation, and if the reverse rotation switch 47c is touched, the automatic tuning starts by reverse rotation. When the return switch 47d is touched, the screen is switched to the test operation function selection screen 45 (return). In addition, the station number and the model name set as described above are displayed on the auto tuning screen 47, and the current state, for example, that the auto tuning is being performed or the auto tuning is stopped is displayed. .

Next, operations of various settings, various monitors, test operations, auto-tuning, and the like by the programmable display 2 configured as described above will be described.

First, the inverter management program shown in FIG. 4 is started, and the initial screen 31 is called. By touching the connection model setting switch 31a from the initial screen 31, a connection model setting screen 32 shown in FIG. 6 is displayed. At this time, the display control unit P1 of the inverter management program calls the designated inverter management screen data by referring to the screen link data in the inverter management data, and displays the connection model setting screen 32. In the setting of the connection model name on this screen, the connection model selection window 52 called via the selection window 51 also by referring to the screen link data
The setting input section P2 of the inverter management program refers to the model name list data in the inverter management data and registers the model name input by the user as the model name data of the associated station number in the inverter management data.

In setting parameters, a parameter setting screen 34 (FIG. 9) is called via a parameter setting target selection screen 33 (FIG. 8). Then, based on the parameter number set on the parameter setting screen 34 and the address information included in the model name data and the parameter list data, the parameter is set from the specified address of the parameter memory 122c in the inverter 1 of the specified station number. Data is read. The read parameter data is written to the FEPROM 22c at an address specified for each parameter.

In this state, on the parameter setting screen 34, the read parameter is displayed as the current set value on the line touched as described above, while the parameter value is set using the displayed keyboard 54. Is done. Then, by touching the write key 54h, the FEPROM 2
If the current setting value in 2c is changed, it is rewritten with the changed value. At the same time, the changed value is transmitted to the inverter 1 by the communication control unit P3 based on the model name data, and written to the corresponding address of the parameter memory 122c based on the address information.

Thus, the parameters of inverter 1 are updated. However, if the set value of the parameter is not changed, the set value is not rewritten even if the write key 54h is operated. Also, by using the batch read and batch write functions, the parameters for the inverter 1 of the designated station number are read and written collectively.

In the above parameter setting, parameter data is read from the inverter 1 in advance and
Since the parameter data stored in the ROM 22c is read, there is no need to communicate with the inverter 1 every time the parameter is set. Thus, when different parameters are successively set, the current setting value can be promptly displayed when each row is moved in the parameter setting table 34a.

In the inverter 1, values of parameters and the like are handled in a form that does not include a decimal point.
It is converted into a value including a decimal point by the arithmetic processing by the display control unit P1. Conversely, when the value including the decimal point displayed on the programmable display 2 is written into the inverter 1, it is converted into a value not including the decimal point.

The parameter data set as described above is transferred between the inverter 1 and the FEPROM 22c and between the FEPROM 22c and the SR
It is exchanged between the AM 22b and the RAM 22b and the CF card 9. The parameter copy unit P4
The parameter data is copied to the read source and the write destination specified on the parameter copy screen 36 (FIG. 15).

More specifically, when parameter data is copied from the FEPROM 22c (recording medium) to the parameter memory 122c (recording medium) of the inverter 1, the inverter 1 of the station number set on the parameter copy screen 36 by the setting input unit P2 is used. On the other hand, after confirming or changing the set value on the parameter setting screen 34 called via the parameter confirmation switch 36l, the communication control unit P3 writes the parameter data. Conversely, when copying the parameter data from the inverter 1 to the FEPROM 22c, the parameter data is read from the inverter 1 of the set station number to the FEPROM 22c by the communication control unit P3.

As described above, by using the parameter copy function between the FEPROM 22c and the inverter 1, even if the above-described parameter setting is not performed, the parameter data can be exchanged between the two. This makes it possible to easily back up and update the parameter data.

Next, from the FEPROM 22c to the SRAM 2
When the parameter data is copied to 2b (recording medium), the parameter data of the file specified on the parameter copy screen 36 is written to the SRAM 22b. At this time, if a comment is input on the parameter copy screen 36, the data is also written into the SRAM 22. Conversely, when the parameter data is copied from the SRAM 22b to the FEPROM 22c, the parameter of the file specified on the parameter copy screen 36 is changed to the FEPR.
It is written to the OM 22c.

Further, the SRAM 22b and the CF card 9
When copying parameter data to / from the (recording medium), the parameter copy unit P4 uses the CF function window 8
5, the parameter data of 50 files read from one is written to the other. Thus, the parameter data is backed up and stored in the CF card 9 which is detachable from the programmable display 2. Therefore, by attaching the CF card 9 to another programmable display having the same function as the programmable display 2 and writing the parameter data, the programmable display 2
Can be written to the other programmable display device described above, and vice versa. Further, even when the set value of the parameter is temporarily changed, the parameter can be returned to the original set value by the backup data.

Between different station numbers, parameters are copied as follows.

First, with the copy source station number set on the parameter copy screen 36, the data transfer switch 36
When the execution switch 83a is touched in the data transfer execution confirmation window 83 called by touching f, the designated copy source parameter data is transmitted to the programmable display 2 and stored in the FEPROM 22c. Subsequently, when the station number of the copy destination is set on the parameter copy screen 36 and the execution switch 83a is touched on the data transfer execution confirmation window 83 called by touching the data transfer switch 36g, the FEPROM 22c
Is written into the designated copy destination inverter 1.

Further, when copying parameter data to the inverter 1 of another station, the above procedure is repeated. In copying between different station numbers, the parameter data from the inverter 1 of the copy source is stored in the FEPROM 22c, and is stored on the parameter setting screen 34 called by touching the parameter confirmation switch 36l on the parameter copy screen 36. You can check and change parameters.

The present programmable display 2 monitors the output values of the inverter 1 such as frequency, current, voltage, etc.
The operation data from the inverter 1 of the designated station number is fetched from the communication control unit P3 as inverter management data. This operation data is passed to the display control unit P1 and displayed on a desired monitor screen.

For example, when performing data display using the data display screen 38 (FIG. 21), after a station number is input, a monitor item selection window 91 is displayed using monitor item data.
After the monitor item is specified in (Fig. 22), monitor ON /
Monitoring is started by touching the OFF switch 38b. Then, the communication control unit P3 requests the inverter 1 of the designated station number to transmit the operation data of the designated monitor item. When the inverter 1 transmits operation data in response to the request, the operation data is transmitted to the communication control unit P3.
Is passed to the display control unit P1, and the display control unit P1 displays the value of the operation data on the data display screen 38 almost in real time. The operation data is taken in as inverter management data as needed.

The monitor using the meter display screen 39 (FIG. 24) and the oscilloscope screen 40 (FIG. 25) processes the operation data in substantially the same manner as the monitor using the data display screen 38. However, when the oscilloscope screen 40 is used, the monitored operation data can be stored in the CF card 9.
In this case, the operation data from the communication control unit P3 is written to the CF card 9 according to the instruction of the display control unit P1. When the alarm history is displayed using the alarm history screen 42 (FIG. 28), the display control unit P1 instructs the communication control unit P3 in response to a request from the setting input unit P2. To get.

In the monitor using the output terminal monitor screen 41 (FIG. 27), when the monitor ON / OFF switch 41b is touched on the displayed output terminal monitor screen 41,
Monitoring of the energization state of each output terminal in the inverter 1 of the designated station number starts. At this time, the display control unit P1
Is based on the terminal name data included in the model name data.
While the terminal names are displayed on the output terminal monitor screen 41, in response to a request from the input setting unit P2, the communication control unit P3 is instructed to acquire the energized state of the output terminal of each terminal name.
Upon receiving this instruction, the communication control unit P3 accesses the memory area of the address assigned to each output terminal for the inverter 1 of the designated station number, and acquires the conduction state of each output terminal. Then, the display control unit P1 displays the energized state on the output terminal monitor screen 41.

When displaying information on a major failure alarm using the failure diagnosis screen 43 (FIG. 30) or the extended alarm history screen 44 (FIG. 31), the display control unit P1 sends an alarm from the inverter 1 through the communication control unit P3. Acquire the last operation data and alarm data. At this time, only an alarm of a serious failure is requested from the communication control unit P3 to the inverter 1.

In the case of the extended alarm display, the alarm acquisition time (substantially equal to the occurrence time) is indicated by the display control unit P1.
, It is possible to know the alarm occurrence time. Further, by storing the extended alarm history in the CF card 9, it is possible to confirm the state of a serious failure that occurred during nighttime operation. In addition, by performing various processes such as statistical processes on the data of the CF card 9 using application software (for example, spreadsheet software) of a personal computer, the results can be used for troubleshooting.

When a test operation using the test operation screen 46 (FIG. 34) or an auto-tuning using the auto-tuning screen 47 (FIG. 35) is performed, based on the set value and the operation instruction given by the input setting section P2. When the display control unit P1 instructs the communication control unit P3, data necessary for test operation and auto tuning is transmitted from the communication control unit P3 to the inverter 1. Inverter 1
Performs test operation and auto-tuning based on the received data.

As described above, in the motor control system according to the present embodiment, the FA that can be normally installed in a severe environment is used.
Since the programmable display 2 as a device is always connected to the inverter 1 to perform various settings and monitoring, a personal computer is brought to the site where the inverter 1 is installed, as in a conventional application program for setting and monitoring. Eliminates the need.

In a conventional programmable display,
It is possible for a user to create a user screen and set parameters, models, station numbers, and the like using the processing instruction word W described above. However, in this method, one setting is assigned to one processing instruction word W.
Not only does such work take a great deal of trouble for a large number of parameters such as 0 to 300, but also it is necessary to create a dedicated screen for each model. Moreover, when setting the parameters, the inverter 1
Since it is necessary to always communicate with the inverter 1 in order to read the parameter from and write the changed value, there is a disadvantage that the parameter update operation cannot be performed smoothly due to the time required for the communication.

On the other hand, in this motor control system,
By reading in advance the parameters stored in the inverter 1 into the FEPROM 22c of the programmable display 2, communication with the inverter 1 is not performed when setting the parameters. Thereby, in switching between the inverter management screens and in a line feed operation on the inverter management screen, it is not necessary to communicate with the inverter 1 to read the parameters each time, so that the parameter setting can be performed smoothly.

In the programmable display 2, FE
While the PROM 22c exchanges parameter data between the inverter 1 and the SRAM 22b,
The parameter data is exchanged between the SRAM 22b and the CF card 9 to back up the parameter data.

Thus, it is possible to easily save parameter data and exchange parameter data between different station numbers. Therefore, the same parameter can be set for a plurality of inverters 1 by performing parameter setting for one inverter 1 and copying the parameter to the inverter 1 of another station. Therefore, when the same parameter is set for a plurality of inverters 1, the parameter can be set efficiently.

Further, when products to be manufactured differ from day to day in a factory line or the like, the parameter setting of the inverter 1 on the line may be changed each time.
In such a case, the parameter data is stored in the SRAM 22b.
By adding a comment when saving the product, it is possible to easily determine that the product has been changed. Therefore, parameter data can be easily managed, and parameters can be easily changed according to products.

By adopting the CF card 9 as a recording medium, a CF card driver 23 having no mechanical part such as a flexible disk driver is mounted on the programmable display 2. Therefore, good read / write operation can be maintained without being adversely affected by high temperature, high humidity, and the like at the production site.

Further, in the programmable display device 2, in the inverter management screen, the connection model setting screen 32 for setting the connection model name is first shifted to each inverter management screen. Can be provided. Moreover, with such a screen configuration, it is possible to prompt the user to first set the connection model name, and to prevent forgetting to set the connection model name.

In this embodiment, an example in which the inverter 1 is used as a control device has been described. However, the present invention controls an object to be controlled, and sets parameters on the programmable display 2 and monitors operation data. The device to be managed is not limited to the inverter 1 as long as the device can perform the operation. For example, a temperature controller other than the inverter 1 is suitable as a control device.

The temperature controller controls a temperature measuring device such as a thermocouple for measuring the temperature and a temperature adjusting device such as a heater for controlling the temperature, and controls the rise, fall, and maintenance of the temperature. When such a temperature controller is connected to the programmable display 2 of the present embodiment instead of the inverter 1, the programmable display 2 sets a PV value (Process Value; ° C.), which is a measured value, as a set value. Monitoring such as the SV value (Set Value; ° C), the control output (%) to the heater, and setting of each parameter can be performed using a screen similar to the inverter management screen.
