Wait on Notification (G Dataflow)

Last Modified: January 9, 2017

Waits until a notifier receives a message.

When the notifier receives a message, this node continues to execute. Use Send Notification to send the message. If a notifier reference becomes invalid such as when another node closes it, the node stops waiting and returns error code 1122. If the notifier does not contain a message, this node waits until the notifier receives a message.

A reference to a notifier. Use Obtain Notifier to obtain a notifier reference.

datatype_icon

ignore previous

A Boolean that determines whether to ignore messages that LabVIEW sends to the notifier before it calls this node.

True If the notifier contains a message before you call this node, this node ignores the previous message waits until the notifier receives another message.
False If the notifier contains a message before you call this node, this node continues to execute.

Default: False

datatype_icon

timeout in ms

Time, in milliseconds, that the node waits for the notifier to receive a message. -1 indicates never to time out.

Default: -1

datatype_icon

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

datatype_icon

notifier out

notifier unchanged.

datatype_icon

notification

The last message the notifier receives. This data type changes to match the subtype of notifier.

datatype_icon

timed out?

A Boolean that indicates whether the notifier received a message before the node timed out.

True The notifier did not receive a message before the node times out or an error occurred.
False The notifier received a message.
datatype_icon

error out

Error information. The node produces this output according to standard error behavior.

Where This Node Can Run:
