Plug-ins created from the Produce data for FlexLogger template send collected data to FlexLogger. Use the Produce data for FlexLogger template as a starting point for creating your own plug-ins that send channel data to FlexLogger.

To create a channel that sends data to FlexLogger, select the Produced by Plugin mode in Create Channel VI. The Create Channel VI is in the Initialize method of the Produce data for FlexLogger template.

You can write string data or waveform data to a FlexLogger channel. To write string data, specify 1D String (NChan 1 Sample) as the data type in the Write Data VI. The Write Data VI is in the Process method of the Produce data for FlexLogger template.

When writing strings, you can optionally specify the time stamp at which the string is written. If you don't specify a time stamp, the VI will use the current time as the time stamp for when the string is written. The following image shows all of the inputs and outputs for the Write Data VI.

To send waveform data, specify either a one or two-dimensional array of doubles.

Writing waveforms that overlap in time disrupts visualization and logging capabilities of FlexLogger. The Produce data for FlexLogger template uses the Set Stream Timing VI to send data to FlexLogger without overlap errors. The Set Stream Timing VI is in the Configure Session method and defines the waveform dt and Start Time timing parameters.

Since the Configure Session method always executes before the Process method, the timing information for the output channel updates after every configuration change.
