15.1.1 Historian data and log
The 1600 transmitter offers a licensable Data Historian option. If enabled, the transmitter automatically saves
information about specific process and diagnostic variables. You can generate a log from this data that tracks
totalizers and inventories with 21 days worth of data. The historian log is an ASCII file in .csv format.
Contents of the historian log
There are two types of historian records:
1-second raw data
The current values of process and diagnostic variables, recorded at 1-second intervals.
5-minute average data
The minimum and maximum values of the 1-second raw data, plus the average and
the standard deviation, calculated and recorded at 5-minute intervals.
When you generate the log, you can specify which type of record you want to see.
The historian in the transmitter internal memory contains a minimum of 7 days of 1-second raw data and
30 days of 5-minute average data.
Each record contains data for the following process and diagnostic variables:
• Timestamp
— Format: Military time
— Time and time zone: Transmitter clock
• Mass flow rate (kg/sec)
• Volume flow rate (l/sec) or GSV flow rate
• Density (g/cm³)
• Line temperature (°C)
• External temperature (if available)
• Pressure (if available)
• If concentration measurement is enabled:
— Standard volume flow rate
— Net mass flow rate
— Net volume flow rate
— Referred density
— Concentration
• If API Referral is enabled:
— CTPL or CTL
— Corrected density
— Corrected volume flow rate
• Alert status registers (hexadecimal format)
• Live zero (kg/sec)
• Tube frequency (Hz)
• Drive gain (%)
