Retriever software programs. These are user-selectable binary or ASCII format files. The
files are stored as compressed .zip files to increase storage and decrease user download
times. These files may be retrieved and deleted from the instrument using the available
communications protocols. Please refer to the specific protocol manual or section 5.5
(Zmodem and FTP) for details. A file cannot be deleted while being read by another
device.
The Waveform Recorder file "
WR1_nnnn.CFG
" or "
WR2_nnnn.CFG
" will contain the
event parameters including the names of the channels, time of start of file, time of trigger,
and sampling frequency for each cycle. The file "
WR1_nnnn.DAT
” or "
WR2_nnnn.DAT
"
contains the time of each sample and the data. The data values are integers and can be
scaled back to primary units using the scale factors in the .CFG file. The file name format,
"WR1_nnnn.CFG"
and
"WR1_nnnn.DAT,”
indexes automatically from
"WR1_0001.xxx"
to
"WR1_9999.xxx"
. Similarly, Waveform Recorder 2 files will be stored as
"
WR2_nnnn.CFG
" and "
WR2_nnnn.DAT
".
Upon power-up (or re-boot), the M87x notes the highest index number in memory, and will
increment by one for the next file. If there are no waveform records, the next one will be
WR1_0001. If there is a WR1_0034 in memory upon re-boot, the next file will be
WR1_0035. Note that if the stored files are deleted, but the M87x is not re-booted, it will
continue to index in sequence as if the files were still there.
The Disturbance Recorder stores files in the same manner as the Waveform Recorder.
Files from Disturbance Recorder 1 will be saved as "
DR1_nnnn.CFG
" and
"
DR1_nnnn.DAT
,” with the same indexing sequence as the waveform files. Similarly,
Disturbance Recorder 2 files will be stored as "
DR2_nnnn.CFG
" and "
DR2_nnnn.DAT
".
The Trending file "
TR1.CFG
" will contain the event parameters, including the names of the
channels, time of start of file, and trend interval for each measurement. The file
"
TR1.DAT
" contains the time of each sample and the data. The data values are integers
and can be scaled back to primary units using the scale factors in the .CFG file.
5.4.4a Comtrade ZIP Files
The .CFG and .DAT files are combined into a single .ZIP file, which is placed in the
c:\DATA\ or e:\DATA directory (see section 5.5). This file may be retrieved using FTP,
Zmodem, or protocol specific file transfer methods. Note that the .ZIP file may take up to 1
minute to appear in the c:\DATA\ directory after the records are created.
5.4.5 IEEE Long File Naming Convention
The 70 Series IEDs are capable of creating record files that meet the IEEE C37.232-2007
standard for file names. The long filename feature is enabled and configured on the
Identity Page of the 70 Series Configurator. The Identity Page is shown below with factory
default values. Settings relevant to long filename configuration are highlighted in green.
