Oscillography Files Retrieval; Data Logger Setpoints - GE Multilin F650 Instruction Manual

5.2 PRODUCT SETUP
AVAILABLE RECORDS: This is the number of records in COMTRADE format stored in the relay, which can be retrieved
by serial communication (ModBus RTU) or Ethernet (ftp, tftp). The range is 0 to 20.

5.2.4.4 OSCILLOGRAPHY FILES RETRIEVAL

Oscillography files can be retrieved using EnerVista 650 Setup software, or the web server at "http:\\relay IP address".
For obtaining oscillography
"Actual>Records>Waveform capture". The top of the window shows the number of the last oscillography record stored
by the device (Newest Record Number), followed by the maximum number of oscillos available in the unit (Available
Records in Device), programmable by setpoint. Clicking on the "View header" button, the system will show the header of
the record selected at "Select Record".
Clicking on the "Download" button, the three files (*.DAT, *.HDR, *.CFG) that form the oscillography record in COMTRADE
standard will be retrieved, and they will be viewed automatically if the GE-OSC software is installed in the computer.
Retrieved oscillographies can be viewed using any Comtrade format viewer. EnerVista 650 Setup software stores by
default oscillography records in folder ".\EnerVista 650 Setup\files\osc", in the same directory where the program is
installed, using "OSCxxx.DAT", "OSCxxx.CFG", "OSCxxx.HDR" names, where xxx is the corresponding record number.
The oscillography retrieval can be done using serial communication (ModBus RTU) or Ethernet (ftp, tftp).
The F650 data logger can store information of up to 16 analog channels, among all channels available in the relay, with a
sampling rate selectable by setpoint. The memory capacity of the data logger is fixed, 64 Kbytes, two bytes per analog
5
measure. Selected channels will take all the available memory space. Therefore, the storage days will depend on the
selected number of channels and sampling rate.

5.2.5.1 DATA LOGGER SETPOINTS

Data logger setpoints can be found at "setpoints>Product Setup>Data Logger".

Function permission (Function):Enabling this setpoint allows to start storing analog channel information programmed in
this tool.
Data Logger Rate: the data logger can be configured in rates of 1 second, and 5, 10, 15, 20, 30 and 60 minutes
Data Logger Analog Channel X (Data Logger Chnl X): Analog Channels programmable in the data logger. The X value
has a range from 0 to 16.
Any setpoint change in the Data Logger will erase all the stored information.
