B.3 FILE TRANSFERS
datalog.cfg and datalog.dat
To read the entire data logger in ASCII COMTRADE format, read the following files.
dataloga.cfg and dataloga.dat
To limit the range of records to be returned in the COMTRADE files, append the following to the filename before writing it:
• To read from a specific time to the end of the log: <space> startTime
B
• To read a specific range of records: <space> startTime <space> endTime
• Replace <startTime> and <endTime> with the number of seconds since Jan. 1 1970 as numeric text
f) READING EVENT RECORDER FILES
To read the entire event recorder contents in ASCII format (the only available format), use the following filename:
EVT.TXT
To read from a specific record to the end of the log, use the following filename:
EVTnnn.TXT (replace nnn with the desired starting record number)
To read from a specific record to another specific record, use the following filename:
EVT.TXT xxxxx yyyyy (replace xxxxx with the starting record number and yyyyy with the ending record number)
g) READING FAULT REPORT FILES
Fault report data has been available via the UR file retrieval mechanism since UR firmware version 2.00. The file name is
faultReport#####.htm. The ##### refers to the fault report record number. The fault report number is a counter that
indicates how many fault reports have ever occurred. The counter rolls over at a value of 65535. Only the last ten fault
reports are available for retrieval; a request for a non-existent fault report file will yield a null file. The current value fault
report counter is available in "Number of Fault Reports" Modbus register at location 3020h.
For example, if 14 fault reports have occurred then the files faultReport5.htm, faultReport6.htm, up to
faultReport14.htm are available to be read. The expected use of this feature has an external master periodically poll-
ing the "Number of Fault Reports' register. If the value changes, then the master reads all the new files.
The contents of the file is in standard HTML notation and can be viewed via any commercial browser.
