Restarts the watchdog timer using the values you specify in the Watchdog Timer Configure node.

If the countdown of the watchdog timer has not yet started, this node starts the countdown.

Programming Patterns
connector_pane_image
datatype_icon

watchdog ID in

ID of the watchdog timer object.

datatype_icon

restart after expiration

Boolean value that specifies whether to restart the watchdog timer if it has expired.

True Restarts the watchdog timer if it has expired.
False Does not restart the watchdog timer if it has expired.

Default: False

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

watchdog ID out

ID of the watchdog timer object.

datatype_icon

watchdog status

Status of the watchdog timer.

Name Description
disabled The watchdog timer is disabled.
expired The watchdog timer has expired.
running The watchdog timer is running.
datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
