Reads a Message that a top-level Actor sent to its caller. Use this VI to interact with code that is not in a VI that belongs to an Actor.
Reference needed to read Messages from a top-level Actor.
Time, in milliseconds, this VI has to read the Message. The default is -1, which specifies no timeout.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
A duplicate of message dequeuer in.
Message read from the queue. If timed out? returned True, message returns the default Message class.
Error information.
The node produces this output according to standard error behavior.

Priority level at which LabVIEW NXG sent the Message.
Name | Description |
---|---|
Low | Specifies that the Actor processes the Message after Messages of all other priorities. The Actor processes multiple low-priority Messages in the order it receives them. |
Normal | Specifies that the Actor processes the Message after critical- and high-priority but before low-priority ones. The Actor processes multiple normal-priority Messages in the order it receives them. |
High | Specifies that the Actor processes the Message first. The Actor processes multiple high-priority Messages in the order it receives them. Only emergency stop and last ack Messages supersede high priority Messages. |
