16.3.4.3. Information from the system on the configuration and status of the Data Logger
The following information is provided on the status of the data logger:
STATUS
Waiting trigger: this means that the data logger is enabled and waiting for the occurrence of the event selected
as the trigger.
Data Logger triggered: this indicates that the trigger event has occurred and the data logger is still recording.
Data Logger stopped: this means that the recording has been terminated either because it has been completed or
because a data logger stop command has been received, or because a trip has occurred.
CONFIGURATION
Data Logger Config: indicates whether or not the data logger is active
Data Logger Trigger Type: indicates the stop event (trigger) setting
Data logger stopping delay: indicates the delay for the stop
16.3.5. Data logger commands from the system
When a data logger stop command is given, the recording is stopped from the system. The subsequent recording is enabled by
a Restart trigger command. The same applies to the operator panel, as illustrated in par. 16.4.2.6.
Example of data logger operation
The following figure shows an example of how a trigger works, the data logger’s function, the effect of the stopping delay and of
the restart and subsequent stop commands on the data saving procedure
