Owning Palette: Message Queue VIs (Actor Framework)

Requires: Base Development System

(Filename: Actor Framework.lvlib:Message Enqueuer.lvclass:Enqueue.vi)

Sends a message.

In most cases, instead of using this method, National Instruments recommends using the Actor Framework Message Maker dialog box. This dialog box helps you create the code that defines and sends the message. Use the Enqueue VI only if the VI that creates the message is not the one that sends it.

Message Enqueuer in specifies the reference needed to send a message to an actor.
Message specifies the message to send.
Message Priority specifies the placement of the Message in the message queue. This placement determines when the actor will process the message.

0Low—Specifies that the message will be processed after messages of all other priorities. Multiple low-priority messages are processed in the order they are sent.
1Normal (Default)—Specifies that the message will be processed after critical- and high-priority messages but before low-priority ones. Multiple normal-priority messages are processed in the order they are sent.
2High—Specifies that the message will be processed first. Multiple high-priority messages are processed in the order they are sent. High-priority messages can be superseded only by an Emergency Stop or Last Ack message, both of which have critical priority.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Message Enqueuer out returns a duplicate of Message Enqueuer in.
error out contains error information. This output provides standard error out functionality.
