IMAQIOExpirationAction Constants

IMAQIOExpirationAction constants are the constants for the expirationAction parameter of the imaqIOWatchdogConfigure method in the NI-IMAQ I/O library. Use these constants to specify what action to take when the watchdog timer expires.

• IMAQIO_EXPIRATION_ACTION_INDICATOR_ONLY—Displays a message when the watchdog occurs.
• IMAQIO_EXPIRATION_ACTION_ASSERT_TTL_OUT_0—Drives the TTL Out 0 line when the watchdog occurs.
• IMAQIO_EXPIRATION_ACTION_SHUTDOWN—Shuts down the NI-IMAQ I/O device when the watchdog occurs. Refer to imaqIOEnableShutdown for information about enabling shutdown.
