Wait on Notification from Multiple with Notifier History (G Dataflow)

Last Modified: January 9, 2017

Waits until a notifier within an array receives a message. This node tracks the most recent message and timestamp for each individual notifier within an array.



An array of notifier references. Use Obtain Notifier to obtain a notifier reference.


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


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


error in

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

Default: No error


notifiers out

An array of the notifier references from which messages were received. The indexes of this array correspond to the indexes of the notifications output array. From the notifiers out array, you can determine which messages came from which notifiers--the first value comes from the first notifier, the second value from the second notifier, and so on. If an error occurs, this array contains references to the notifiers that caused an error.



An array of the last messages the notifiers receive. This data type changes to match the subtype of notifiers, unless the subtype is an array. If the subtype is an array, the data type becomes a cluster of arrays.


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.

error out

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