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 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
• 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.
When data/event logging is enabled, the transmitter will automatically store the following
measurement data:
Free chlorine
• Date and time
• ppm chlorine
• Temperature
• Sensor current
pH
• Date and time
• pH
• Temperature
• mV
• Glass impedance
• Reference impedance
• Raw pH (if displayed pH has temperature correction applied
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.
