Abstract

PURPOSE: To facilitate setting of a measuring condition by a method wherein when some input modules are the same type, a measuring condition is set to one of the modules and to the other by copying. CONSTITUTION: When power is turned on, a microprocessor 60 reads an input module via an acquisition controller 20 for knowing what type the module is and stores the content thereof to a system memory 40. An indication of prompting the setting of measuring conditions, e.g. a value of range, on/off of a filter and an input type in accordance with information of channel obtained at the power-on time corresponding to the type of each of the input modules, is displayed on a display device 80 in the setting of the measuring conditions.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of a measuring apparatus according to the present invention. In the figure, reference numeral 10 denotes a plug-in type input module unit, which includes modules 10a to 10n. Each module has 2 channels (C
H) input circuit is incorporated. In each module, a circle indicates an input connection terminal for each channel. 20 is a controller for acquisition,
30 is an acquisition memory (RAM), 40 is a system memory (RAM), and 50 is a read-only memory (R).
OM), 60 is a microprocessor (CPU), 70 is a keyboard, and 80 is a display. These units are connected to each other via the bus 90 together with the input module unit 10.

In such a configuration, the analog inputs to be measured applied to each channel CH of the modules 10a to 10p constituting the input module section 10 are respectively normalized in the input module and then A / D converted. Is converted into digital data by a device (not shown), and the digital data is acquired by the acquisition controller 2
It is stored in the acquisition memory 30 under the control of 0. The setting of the measurement conditions of each of the input modules 10a to 10n is performed by the microprocessor 60 according to the program stored in the ROM 50. This measurement condition is stored in the system memory 40 for each of the input modules 10a to 10n or for each channel. The measurement conditions stored in the system memory 40 are the keyboard 7
It is input by operating the 0 key. System memory 4
The measurement condition is stored in 0 as described above. Measurement data is obtained from the acquisition memory 30 via the acquisition controller 20 controlled according to the measurement conditions. The measurement data is the microprocessor 60.
Is given to the indicator 80 via the bus 90 under the control of
The display 80 displays the data for each channel.

Here, it is assumed that a plurality of types of modules are used as the modules 10a to 10n, which form the input module section 10, for example. Input module 10a (1CH, 2CH) ... universal module 〃 10b (3CH, 4CH) ... 〃 〃 10c (5CH, 6CH) ... high-speed module 〃 10d (7CH, 8CH) ... universal module ・ ・ ・ ・ 〃 10n (31CH, 32CH) ) ... Universal module Of the input modules, the modules except 10c are universal modules of the same type. That is, although the input module unit 10 is composed of a plurality of types of modules,
Among them, there are a plurality of input modules of the same type, and these mixed input modules can be inserted into arbitrary positions in an input unit (not shown) by a plug-in method.

As described above, the different types of input modules 1
The setting of the measurement conditions of the measuring apparatus according to the present invention having 0a to 10n will be described below according to the flow shown in FIGS. 2 is a flow for obtaining the type of module, and FIG. 3 is a flow for copy processing. First, the case of obtaining the type of module according to the flow of FIG. 2 will be described.

When the power is turned on, the microprocessor 60 reads out what kind of input module it has, through the acquisition controller 20, and stores the read-out content in the system memory 40 (steps ~). Depending on the type of each input module when setting the measurement conditions, the measurement conditions necessary for the setting, such as the range value and the filter on / off status, are obtained based on the channel information obtained when the power is turned on.
Display 80 that prompts you to turn off or set the input type
Is displayed in. Keyboard 7 for the above 3 measurement conditions
When the setting is made by operating the 0 key, the above setting data is stored in the system memory 40 as the contents of the acquisition of the channel. After that, the microprocessor 60 sets the acquisition controller 20 by the program stored in the read-only memory 50 according to the content stored in the system memory 40. The above operation is performed for all the channels, and the measurement conditions are stored in the system memory 40 for each difference in the type of the input module.

Next, the operation of the copy process will be described with reference to FIG.
The flow will be described. The keyboard 70 is provided with keys for the copy function. When this copy key is pressed, the microprocessor 60 reads the number of the currently set channel from the system memory 40 (step), and also reads the type of the input module corresponding to the channel number from the system memory 40 (step). ). At the same time, the measurement conditions set for that channel number (values in the above range, filter on / off,
Alternatively, the input type or the like) is read from the system memory 40 (step). Next, the search start channel number (channel 1) is set to the microprocessor 60 in order to detect a module of the same type as the current module type from the multipoint modules set by the plug-in.
Sets. When the search start channel number is set, the module type of the search channel number is read from the system memory 40 (step), and it is compared whether or not the modules are of the same type (step). If the retrieved modules are of the same type, the measurement conditions having the same contents as the acquisition setting of the channel just set are stored in the system memory 40 of the corresponding channel (step). When this storage is completed, set the search channel number to +1
(Step), and the same search operation is repeated until all channels are completed (step). This makes it possible to set the same settings for the acquisition of modules of the same type.

As described above, according to the present invention, when the input modules have the same type of module, the measurement condition is set for one of the modules and the other modules are set for the measurement condition by copying. Because I configured
For example, it is possible to obtain a multi-channel measuring device which has a large number of input modules and whose measurement conditions can be extremely easily set for each input module even if it is a plug-in type.
