When using multiple devices at the same time, it is necessary to initialize
each device and obtain a different ID.
Execute functions by specifying the ID of each device. At the time of termination,
perform termination processings for each device.
The following example is an example using multiple devices.
Use two AD16-16(LPCI)L and one DA16-4(LPCI)L, and each device is set
to the following device name.
The variables that store the ID of each device are ID_AD1, ID_AD2 and ID_DA1
AD16-16(LPCI)L 1st : AIO000
AD16-16(LPCI)L 2nd : AIO001
DA16-4(LPCI)L : AIO002
