Watchdog Configure
Sets the specified timeout value and expiration actions of the watchdog. This VI returns the actual value to which the timeout was set because the timeout value might be coerced for certain watchdog hardware. It also returns an occurrence refnum for the occurrence expiration action.

timeout is the timeout period for the watchdog timer specified in seconds. The timeout period specifies the amount of time that must elapse before the watchdog timer expires. The timeout period is coerced to a value determined from available timebase and initial count values. The default is 1 s. | |||||||||||||||||||||||||||||||||||
 |
expiration actions specifies which actions to take when the watchdog timer expires. Valid expiration actions are reset, occurrence, trigger line 0, trigger line 1, trigger line 2, trigger line 3, trigger line 4, trigger line 5, trigger line 6, trigger line 7, and SMB line 0. You can use any of these actions in combination.

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

watchdogID identifies the watchdog timer application. | |||||||||||||||||||||||||||||||||||
 |
timeout value returned is the timeout period for the watchdog timer specified in seconds. The timeout period specifies the amount of time that must elapse before the watchdog timer expires. The timeout period is coerced to a value determined from available timebase and initial count values. The default is 1. | |||||||||||||||||||||||||||||||||||
 |
occurrence is the occurrence associated with the interrupt action upon expiration of the watchdog timer. | |||||||||||||||||||||||||||||||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
