B.4.2 Digital input interrupt utility
The digital input interrupt utility can be accessed in the following path: C:\Program
Files\Advantech\UNODIO\Examples\VB\DIINT.
1. Click “Start”. The application will read the DI port value, according to the user-
specified clock source, and then display the current DI port value. The eight sig-
nal lamps correspond to the eight bits of DI port.
2. Click "Enable". The application will enable an event as specified by the user and
track the event as well as displays its frequency. Here, "Enable" stands for
"enable the event", "Rising" for "rising edge triggering" and "Falling" for "falling
edge triggering". "I/S" shows the current interrupt count checked each second.
3. Click "Disable" to stop the previously enabled event.
4. Click "Exit" to quit the application.
