Owning Palette: Advanced VIs (Actor Framework)

Requires: Base Development System

Waits for the specified amount of time and then sends a message to an actor a specified number of times.

# Copies specifies the number of times this VI sends the Message. The default is 0, which specifies to send the message an infinite number of times. Use the Delivery Notifier to stop sending the message.
Message Enqueuer specifies the reference needed to send messages to the actor.
Message specifies the message to send.
Milliseconds To Wait specifies the time, in milliseconds, this VI waits before sending the Message.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
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 High-priority messages can be superseded only by an Emergency Stop or Last Ack message, both of which have critical priority.
Delivery Notifier returns a notifier refnum you can use to preempt or reschedule the message delivery. This output also contains an enum of a typedef with valid values to send to the notifier.

Use the Send Notification function to send the following values to this notifier:
  • Send next copy now
  • Skip next scheduled copy
  • Send next copy now and stop all further copies
  • Stop all further copies
error out contains error information. This output provides standard error out functionality.
