This article proposes an extension of the message handling in the actor framework. It will discuss the possibility to send the results of a message, subVI’s error cluster and return parameters, as asynchronous callback message to another actor from within the actual message, but not the public subVI.
The design is illustrated in the context of CS++. An InstrSimCtrl caller actor requests a measurement value from InstrSim callee actor and displays the result in a one button dialog.
CS++ is a set of LabVIEW libraries extending the NI Actor Framework with features focused on commissioning and test of distributed systems not only in Big Physics experiments. The example and CS++ library sources are published under the terms of EUPL v1.1
