Data Logger

Path in Classic view: Classic view > Datalogger

Description of the function
The function Datalogger allows the recording of data associated with a trigger event. The data recorded are:

analog measurements, i.e. phase currents and line-to-line voltages
digital events, i.e. protection events or alarms, circuit-breaker status signals, protection trips.

IMPORTANT: the function Datalogger requires an auxiliary voltage supply.

Operating principle
When Data Logger is enabled and activated, the device continuously acquires data by filling and emptying an internal buffer (B).

If the trigger event is encountered (A), the device interrupts the acquisition immediately or after a user-definable time called the stop delay (C). Next, it saves all the data in the window (D), which can then be downloaded to a PC for reading and analysis.

A subsequent recording overwrites the previous one in the device memory.

Settings Data Logger

Element	Description
Number of channels	Set the number of recording channels. Each channel has a configuration independent of the others.
Sampling frequency	Frequency of data collection. The higher the sampling frequency, the shorter the recording duration.
Type of memory	Non-volatile (default): the device keeps recording even if it is switched off. The life of the device’s internal battery may decrease significantly compared to the declared value in the absence of the auxiliary power supply. Volatile: the device keeps recording even if it is switched off. When the device is switched on again, it Data Logger reboots automatically, losing all previously stored data.

Start recording

With the device connected and communicating with Ekip Connect, click on Tools > Data Logger.
Check that the status of the command to enable the function is Enabled.
Click on and configure recording.
To cancel the changes, click on Cancel. To save the configuration, click on OK : the settings are automatically saved and transmitted to the device.
Click on Trigger options and set the trigger event.
To cancel the changes, click on Cancel. To save the configuration, click on OK: the settings are automatically saved and transmitted to the device.
To record also after the trigger event, in the graphic representation of the recording drag the recording interval until the desired stop delay is displayed. To save the setting and transmit it to the device, click on Write stop delay.
Click on Active: the function is active and available for recording.

IMPORTANT: once activated, the function remains active on the device regardless of the status of the connection and communication with Ekip Connect.

Download a recording

With the device connected and communicating, click on Download.

Note: the Download button is available only if there is a recording.

Select where to save the file and the interval of the recording you want to download: Ekip Connect saves an .abb file named according to the following syntax: datalogger_YYYYMMDD_Tag_name.

Note: if communication with the device is via a point-to-point connection, it can take up to 5-10 minutes to download the file. With a bus network connection, the operation is faster.

Download only the recording interval with useful data to reduce download times.
