‎Chapter 8 Configuring Recorders Configuring the Waveform Recorder
88 PM180 Substation Automation Unit
The total number of records you must allocate to store the required
number of events (series) is defined as follows:
Number of Records = Number of Records per Series x Number of
Series
For example, if you want to record a 64-cycle waveform sampled
at a rate of 32 samples per cycle, the number of records required
for one waveform series would be:
Number of Records per Series = (32 x 64)/512 = 4.
If you want to allocate space sufficient to store 20 waveform
events (series), you should set up the waveform log file for 4 x 20
= 80 records.
5. Click OK, and send your setup to the device or save to the
database.
6. Click “Setup Recorder”, or click on the “Waveform Recorder” tab.
The following table lists available waveform options.
Option Range Description
Samples per Cycle 32, 64, 128, 256 samples/cycle Defines the sampling rate for the
waveform log
Cycles per Series 16-10848 (32 samples/cycle),
8-5424 (64 samples/cycle),
4-2712 (128 samples/cycle)
2-1356 (256 samples/cycle)
Defines the total duration of the
waveform recording per event/series
Before Cycles 1-20 Defines the number of cycles to be
recorded prior to the event
Num. of Channels 1-26 The number of the simultaneously
recorded channels
7. Select the sampling rate for waveforms.
8. Select the number of cycles to be recorded prior to the event, and
a total number of cycles in the waveform.
9. Add the name for your waveform log file in the “Name” box. It will
appear in the waveform reports.
