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.
Here is an example of using multiple devices.
Use two CNT24-4D(PCI)H and one CNT-3204IN-USB, and each device is set to the following device name
The variables that store the ID of each device are ID_CNT1, ID_CNT2, and ID_USBCNT1
CNT24-4D(PCI)H 1st : CNT000
CNT24-4D(PCI)H 2nd : CNT001
CNT-3204IN-USB : CNT002
