Chapter 6 Logging
Waveform Header
If the value of Record_Indicator is 2, the LoggingResults.Waveform_Log table
returns the following information. The data type returned is REAL, although
some elements (MAC ID) are better interpreted as UINT32.
If the waveform retrieval is interrupted for more than 60 seconds, the sequence
needs to be reinitialized by writing the Configuration.WaveformFileName table.
Appending the filename with selection switches configured for the next record in
sequence begins the retrieval where it left off before the interruption.
Refer to Waveform Recording (M6 model) on page 93 for more information
about waveform setup, operation, commands, related functions, and retrieval via
ftp and the native Ethernet port.
