  • Download
The Messenger Library for LabVIEW by Dr. James Powell is an extensive library for passing messages between parallel processes. The add-on software uses LabVIEW Object Oriented Programing (OOP) to generalize the communication method, allowing the message sender to use the method provided by the receiver. Please see the instructional videos on YouTube.

Supported communication methods include the following:

- wrappings of simple queues
- user events and notifiers
- complex channels (such as a TCP server and client)

Communication patterns supported include request-reply (the reply is sent to a "reply address" attached to the request), and register-notify (one process sends a registration message to another in order to subscribe to a series of updates). Messages are also LabVIEW OOP objects, each having a “label" and a "reply address", and with child types that carry Objects, Variants, or errors.

Custom debug probes are provided as well as a framework and example templates for dynamically-launched VI "actors". An "Actor Manager" debug tool can be installed through the Tools menu.
