Data logger structure

The data logger can store up to 10,000 events. Depending on the setting for the logging cycle (in
sections of seconds), e.g. for a value of 10,000 s (default value), the events of about 5 days can be
stored.
The data logger stores the following information:
• important user actions, system events, and error messages,
• measured data of the three control loops during incubation operation.
The data logger can be queried using the following commands:
