Abstract

PURPOSE:To easily and surely perform a setting work by making it possible to perform a setting in the same way by also other setting device by transmitting and receiving set data to a target device by a setting device. CONSTITUTION:A setting device 1 outputs data of temperatures, etc., for setting to which the device number specific to a target device 2 is attached to a bus L. The target device 2 fetches the data for setting to which the device number specific to its own is attached of the data in the bus, changes set data, displays it and outputs data for response to the bus L by attaching its own device number as the response. The setting device 1 receives this data for response and confirms it. In these cases, when the setting of set data the same as the device 2 is necessary also in other setting devices 3 and 4, data for setting or data for response which flows in the bus L and to which the device number is attached is fetched and the data is used for the change of the setting and for the change of the display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a setting data transmission device for transmitting setting data such as process amount.

[0002]

2. Description of the Related Art Conventionally, in order to change set value data such as temperature from a control setting device to another target device, the device is specified by using a polling signal through a transmission line and this setting data is set. There is a way to send.

[0003]

However, in such a method, it is impossible to immediately change the other devices that require the same setting information, and the setting information is set for each device by using the polling signal. If not corrected, the same contents will not be reflected in other devices. In other words, there is a problem that the transmission operation for the same setting must be performed many times, and if the setting is incorrect, different setting data will be sent to another device.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a setting data transmission device which is easy and reliable for the setting work.

[0005]

SUMMARY OF THE INVENTION The present invention has been aimed at from a setting device which outputs setting data having a unique device number of a target device to a bus and a data flowing through the bus. It is equipped with a target device that takes in the setting data to which its own device number is attached and attaches its own device number as a response and outputs the response data to the bus,
It is a setting data transmission device for transmitting setting data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a structural explanatory view showing an embodiment of the present invention.

In FIG. 1A, a setting device 1, a target device 2, other setting devices 3, 4, etc. are connected to a bus L such as a common network as a transmission line.

The setting device 1 outputs to the bus L, for example, data such as setting temperature with a device number unique to the target device 2. The target device 2 takes in the setting data to which a unique device number is attached from the data flowing on the bus, changes the setting data, and displays it. The device number is added and the response data is output to the bus L. The setting device 1 receives and confirms the data for this response. In these cases, when the setting data similar to that of the device 2 needs to be set in the other setting devices 3 and 4, the setting data or the response data having the device number flowing through the bus L is fetched,
Used to change settings and display.

For example, as shown in FIG. 1B, the setting data includes the device number "01-05", the setting code "S" indicating the setting data, and the data "300" to be set. ℃ ”is included. In the device number “01-05”, “01” indicates the number of the device itself, and “05” indicates those numbers when there are a plurality of setting items, channels and the like.

Further, for example, the response data is shown in FIG.
As shown in (c), the device number "01-05", the response code "R", and the data to be set "300 ° C" are included.

FIG. 2 is a diagram showing a somewhat detailed configuration. For example, in the setting device 1, the number setting device 10 is used to set the device number of the target device 2, and the device number is added to the setting device 1.
The setting data as shown in (b) is output from the output means 11 to the bus L.

The target device 2 sets a device number unique to itself by the number setting device 20, and determines that the setting data sent by the setting device 1 is attached with its device number. The means 21 determines and takes in. The acquired data is displayed on the display 23, or the processing means 22 performs arithmetic processing and the like necessary for this data. On the other hand, as a response, the device number unique to itself is added from the output means 24 by the number setting device 20 in FIG.
Data for response such as is output to the bus L again.

The data for this response is taken in by the setting device 1, and the confirmation means 13 confirms that the setting is completed.

In the other setting device 3, the same number as the above device number is set in the acquisition number setting device 30, and the setting data or the response data is set in the discriminating means 31. It is determined, selected and loaded, and the required processing is performed by the processing means 32 or displayed on the display 33. Note that the capture number setting device 30 may be capable of setting a plurality of capture numbers, and may be configured to capture all setting data or response data.

In this way, once in the main setting device 1,
The other setting device 3 such as a local setting display device, which only needs to send the setting data to the device 2 targeted for a specific purpose, needs to display other identical data, automatically sends the setting data. I receive it, update it, and display it. It should be noted that the number of each device may be as many as possible as long as it is one or more, and the transmission of the setting data is similarly easily completed.

Further, in the above example, the data about the setting data is transmitted to the bus L, but the inquiry about the setting contents of the target device 2 from the setting device 1 is similarly made. The target device 2 responds and attaches the device number to its setting data,
The same effect can be obtained by sending the data to another device and using it in another device. In addition, as setting data or response data, commands, requests, settings, inquiries about setting contents, etc.
All transport elements for the targeted device are included.

[0017]

As described above, the present invention is a setting data transmission device in which other setting devices can be similarly set by transmitting / receiving the setting data to / from a target device in the setting device. is there. Therefore, once the setting data is sent from the setting device to the target device, other setting devices can receive the setting data almost automatically and surely, and can perform necessary display processing. It is not necessary to repeatedly send the setting data, the setting work is easy, and the setting error is few and certain, and it is possible to transmit the sufficient setting data with a simple configuration. .
