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:
Query:
?:2400:00::cc<CR>
Set the data logger pointer to the oldest entry and output the
first data sets.
Query: ?:2401:00::cc<CR>
Output of the following data sets, the reading pointer automatically moves
gradually from the older entries to the current entries.
Query: ?:2402:00::cc<CR>
0x0004 Actual value low
0x0010 Calibration values too high/low
