Step to Use

1. Specify the desired program name, run the program, and a CUI(Character User Interface) menu that looks like the one above will appear.
Appearance may vary depending on software version.

2. Initialize

  ・When selecting the command [1: AioInit], you can specify the device name.
    Notifies the device driver to start using the specified device.
    When specifying the device name, AioInit will be executed and the CUI menu will be displayed again.

・When selecting the command [2 : AioSetAiRangeAll], you can specify the range.
When specifying the range, AioSetAiRangeAll will be executed and the CUI menu will be displayed again.

Depending on the device used, the setting may not be effective unless the input range is changed with the jumper pin on the device.

  ・When selecting the command [3 : AioSetAiInputMethod], you can specify the input method.
    When specifying the input method, AioSetAiInputMethod will be executed and the CUI menu will be displayed again.

3. Channel simple input processing

・Every time you select the command [4: AioSingleAiEx] or [5: AioMultiAiEx], the input data will be updated.

・When inputting only one specified channel,

    When selecting the command [4 : AioSingleAiEx], you can specify the channel number.
    When specifying the channel number, AioSingleAiEx will be executed and the input value from the device will be displayed.

・When inputting multiple channels,

    When selecting the command [5 : AioMultiAiEx], you can specify the number of channels.
    When specifying the number of channels, AioMultiAiEx will be executed and the input value from the device will be displayed.
    The starting channel number is fixed at 0ch. For example, if 3 channels are specified, data will be acquired from 0ch to 2ch.

・When the input value is displayed, the CUI menu will be displayed again.

4. Exit

  ・When selecting the command [6 : AioExit], it will notify the device driver that the use of the current device is complete.
    Data can be acquired from different devices (e.g. AIO001, etc.) without terminating the program.
    When AioExit is executed, the CUI menu will be displayed again.

・To perform data acquisition processing again, select the command [1 : AioInit] and specify a new device name to perform device initialization processing.

5. Processing to terminate the program

・When selecting the command [q : Quit], the program will terminate.
