In order to correctly allocate the memory space for TOU profile log files, assign TOU
registers before you set up your TOU profile log files.
To configure a TOU daily profile log file:
1. Configure your TOU registers and TOU schedule before allocating
memory for a profile log file (see
Configuring Summary and TOU
Registers
in Chapter 9).
2. Select Memory/Log from the Meter Setup menu, and then click on
the Log Memory tab.
3. Double click on the Data Log #15 or Data Log #16 partition row.
4. Select the TOU Monthly Profile or TOU Daily Profile in the File
Type box.
5. Select the number of season tariffs in your TOU schedule.
6. Select the maximum number of records you want to be recorded in
the file assuming that a new record is added once a month or once
a day.
7. Click OK and send your setup to the device or save to the
database.
Configuring the Waveform Recorder
Waveform log files are organized as multi-section files that store data for each
recording channel in a separate section.
A regular waveform log file records up to 12 analog channels simultaneously: eight
AC channels (four voltages and four currents), one VDC channel, and up to 48 digital
inputs DI1-DI16, DI17-DI32 and DI33-DI48 organized in three sections as three 16-bit
analog channels.
A single channel waveform record contains 512 points of the sampled input signal. If
a waveform log is configured to record more samples per event than a single record
can hold, the waveform recorder stores as many records per event as required to
record the entire event. All waveform records related to the event are merged in a
series and have the same series number, so they can be plotted together.
The PM180 supports 8 waveform files that can record waveforms at three
programmable sampling rates: 32, 64 or 128 samples per cycle.
To configure a waveform log file:
1. Select Memory/Log from the Meter Setup menu, and then click on
the Log Memory tab.
2. Double click on a waveform log partition with the left mouse
button.
3. Select a file type for your file.
4. Select the maximum number of records to be recorded in the file.
The number of records in the waveform log file needed to store
one waveform event (series) is defined as follows:
Number of Records per Series = Sampling Rate (Samples per Cycle)
x Number of Cycles per Event / 512
