16.1.1 Historian data and log
The transmitter automatically saves information about specific process and diagnostic variables to its working
memory. You can generate a log from this 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's working memory contains a minimum of 4 weeks of 1-second raw data and
10 years of 5-minute average data.
Each record contains data for the following process and diagnostic variables:
