Sends a data set to the first process in the Dataflow Script via a ProcessDataFlowBlock Qbus message. The first process operates on the data and then transfers it to the next process.

Programming Patterns: Sending a Data Set to the First Process in the Dataflow Script

originator?indicates the name of the originator process.
Qbus in is a reference to the collection of message queues, subscriptions, and process states that the Qbus message bus maintains.
high rate (T) indicates whether the data event will be sent to the high rate data flow.
data contains the following elements that make up the data set.
DataGroup specifies the name of the data group whose channels produced the data in Waveforms and/or Map.
Waveforms is an array of the waveforms produced by channels in the DataGroup. If the data group does not contain any channels that produce waveforms, leave this array empty. Note that the waveforms are stored as data value references, meaning you must use an In Place Element Structure to access the waveform data.
Map is a point value map that contains various properties related to the acquisition, as well as any single-point measurements. The map contains values from the time when a process sent the original data set to the first process in the Dataflow Script.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Qbus out returns the reference to the collection of message queues, subscriptions, and process states that the Qbus message bus maintains.
error out contains error information. This output provides standard error out functionality.
