In each of the modules 10a to 10n constituting the input module section 10, whether data from each input module is stored in the acquisition memory 30 is determined by turning on / off a channel (CH) in the module. Is controlled by The on / off setting is performed by key operation of the keyboard 70,
The setting information is stored in the system memory 40. The on / off setting operation by the key operation of the keyboard 70 is performed based on the menu screen of the display 80.

FIG. 2 shows an example of a menu screen for performing on / off setting on the display 80. The setting operation is performed as follows. In FIG. 2, CHI, CH2,
.. CH32 indicate input channels, respectively. When on / off is set for each channel, the cursor is moved to the square for each channel by operating the keys of the keyboard 70, and the enter key on the keyboard 70 is set. Press (not shown). By pressing this enter key, a check mark is added to the square of the channel. The channel marked with this check mark indicates that the channel is turned on. The input signal of the channel is converted into digital data and stored in the acquisition memory 30. When the data of the channel is not stored in the acquisition memory 30, that is, when the input setting is turned off, the enter key is pressed again to remove the check mark. In this way, when setting on / off for each channel for all channels,
The above operation is performed for each channel, but when the number of channels reaches 32 as in the embodiment, the operation is troublesome.

Therefore, the present invention is provided with the functions of "ALL", "ODD" and "EVEN" as shown in the menu screen of FIG. Here, "AL
“L” collects all the channels from CH1 to CH32, “ODD” collects the odd-numbered channels from CH1 to CH32, and “EVEN” collects the even-numbered channels and turns them on / off. It is one that can be set. That is, when the cursor is moved to the square of "ALL" and the enter key of the keyboard 70 is pressed, a mark is added and all the channels are turned on, and the output data of all the input channels are stored in the acquisition memory 30.
Is stored in To turn it off, press the enter key again to release the on state and turn off. Next, "OD
When the cursor is moved to the square of the item "D" and the enter key is pressed, the odd-numbered channels from CH1 to CH32 are turned on, and when "EVEN" is selected, the even-numbered channels are turned on. The on / off setting information of each channel is stored in the system memory 40 respectively. For example, "AL
When "L" is turned on / off, the information of all the channels in the system memory 40 is updated, and the microprocessor 60 controls all the input modules.

As described above, in the present invention, the setting of the ON / OFF of the channel in the input module is set to “AL”.
L, "ODD", and "EVEN" functions are provided so as to collectively or collectively perform multiple channels, but there are cases where it is desired to set each channel individually. In FIG. 2, the function that can be set for each channel is left as shown in the menu screen of FIG.

FIG. 3 shows a processing flow when ON / OFF is set for each of the channels CH1 to CH32. In FIG. 3, the cursor is moved to the square of a desired channel from CH1 to CH32 by operating the keys of the keyboard 70. The selected channel is read from the system memory 40 (step). The on / off information of the selected channel is read from the system memory 40 (step). Keyboard 70

FIG. 4 shows a processing flow of the present invention to which the function of “VEN” is added. In FIG. 4, "ALL", "OD"
When any one of "D" and "EVEN" is selected, the information of the selected "ALL", "ODD" and "EVEN" is read from the system memory 40 (step). The corresponding on / off information in “ALL”, “ODD” and “EVEN” is read from the system memory 40. (Step). The display of □ is inverted by the enter key of the keyboard 70 (step). The inverted contents are written to the corresponding system memory 40. (Step). Next, set the start channel of the setting to C
Set to H1 (step). The on / off information of the corresponding channel is written into the system memory 40 with the inverted contents obtained in the above steps (step). C
H is incremented by 1 (step). This is performed for all channels (step).

In a multi-channel measuring device, there are many items, such as input ON / OFF, which are repeatedly set for each channel. In some cases, individual settings are required. Therefore, by providing individual settings as in the related art and adding “ALL”, “ODD”, and “EVEN” functions to the settings as in the present invention, the setting of the settings can be performed. The number of operations decreases dramatically. For example, when the total number of channels is 32CH, “ALL” is 1/32, and “ODD” and “EVEN” is 1/32.
It is reduced to 16. As described above, in the present invention, the operation is simplified and the operation error is reduced. In addition, in the multi-channel measuring device, there are setting items that can be collectively performed, such as not only turning on / off the input but also displaying / not displaying the item.
