Alarm History
•
The alarm history includes 100 error status entries with the respective time stamps. Whenever at least one entire bit of the overall error status
changes, the complete error status is saved with the current time stamp.
•
Recording is started over each time the device is reset, and data are lost if auxiliary power fails. Recording can be activated with the setting
HISt = YES
in the configuration, or via interfaces.
•
After the ring buffer has been filled to capacity with 100 entries, the oldest entry is deleted each time a new one is recorded.
•
Entries can only be read out via the bus interface or the infrared interface. See the interface description for detailed information.
Data Logger
•
The data logger has enough capacity for 3600 sampled value pairs including actual values and manipulated variables. The logger sampling cycle
can be configured within a range of 0.1 to 300.0 seconds. This results in recording times of 0.1 to 300 hours (6 minutes to 12 days).
•
Recording must be started over again each time the device is reset, and data are lost if auxiliary power fails.

Recording can be started via a binary input, with the setting
LoGG = YES
in the configuration or via interface.
•
After the ring buffer has been filled to capacity with 3600 entries, the oldest values are deleted as new ones are recorded.
