9 Data and event logging and retrieval
9.1 Data and event logging overview
Data and event logging is a standard feature in the Rosemount
™
56 Transmitter. However,
the operator must enable the feature.
When data and event logging is enabled, the Rosemount 56 Transmitter will automatically
store the following events with date and time stamp: faults warnings, calibration data,
calibration results (pass or fail), power on/off cycles, hold on/off, and new sensor
board detected. At your discretion, the transmitter will also store alarm activation and
deactivation as events. The event logger holds 300 events. When the capacity of the logger
is reached, the transmitter removes the oldest events to make room for new events.
When data/event logging is enabled, the transmitter will automatically store the following
measurement data for total chlorine: date and time, ppm chlorine, temperature, and
sensor current.
The transmitter can store up to 30 days of data. When the capacity of the logger is
reached, the transmitter removes the oldest data to make room for new data. Data storage
frequency is every 30 seconds.
