notifier

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:

Desktop OS: Windows

FPGA: Not supported
