Logging Chapter 6

2. Write the Configuration.Log_Read table with Selected Log = 11.

The Configuration.Log_Read

table contains the following elements:

• Element 0. Write a value of 11 to request the next waveform file name

• Element 1: Write a 0 to return the most recent file name first or a 1 to

return the oldest file name first

3. Read the waveform file name from the

LoggingResults. WaveformFileName Data Table

one or more times until

the desired waveform file name is returned.

The LoggingResults. WaveformFileName Data Table

returns a string

containing the requested file name. The file name syntax is described

above in Waveform File Names on page [nn - ed. Please update and link].

The Configuration.WaveformFileName Data Table

contains the file

selection string

‘Waveform_ID_YYYYMMDD_HHMMSS_MicroS_hh/Cycle/

MagOrAng/Channel/iOrder’. Options include the following:

• The desired waveform file name from which to return records

• Appended selection switches:

– Cycle = present cycle offset to be returned; range = 0 … total cycles

in the waveform -1

– MagOrAng; 0 = magnitude data, 1 = angle data

– Channel = the selected channel to return; range = 0 (V1)…7 (I4)

– Order = the range of harmonic components to return; 0 = DC…31,

1 = 32…63

Following the write to the Configuration.WaveformFileName Data Table

each read of the LoggingResults

. Waveform_Log Data Table returns a

successive portion of the waveform record. The appended selection

switches in the filename written to the Configuration.WaveformFileName

Data Table define the first record retrieved in the sequence of data

retrieval. If no selection switches are included with the filename, the first

record returned is the waveform header.

The sequence of waveform data retrieval proceeds according to the

following logic.

For Cycle 0 to N

For MagOrAng = Magnitude to Angle

For Channel = 0 to 7

For iOrder = 0 to 3

Next iOrder

Next Channel

Next MagOrAng

Next Cycle

4. Write the selected file name into the Configuration.WaveformFileName

Data Table.

5. Perform sequential reads of the LoggingResults

. Waveform_Log Data

Table and store the results in a suitable location.
