Data Logs

Data Logging, also referred to as trending, records in real-time the value of a data point in the
system and the time at which the value was recorded.
By default, Symbio™ 800 automatically generates system-created data logs (for equipment and
standard applications) on a 15-minute interval and then stores that data for seven days. Data
storage is a continuous window where only the most recent seven days of data are stored. Data
older than seven days is discarded to make room for the newest data.
A list of data logs can be accessed by clicking D D a a t t a a L L o o g g s s from the left navigation menu. From
this page you can take action on a data log, such as comparing or exporting, by selecting one or
more data logs and then clicking the A A c c t t i i o o n n s s button.

Viewing Data Logs

To view Data logs graphically, select up to six data logs from the Data logs page and then select
V V i i e e w w d d a a t t a a from the A A c c t t i i o o n n s s button. The chart capability supports a time comparison mode that
allows you to compare trend data at different points in time (day-to-day, month-to-month, year-
to-year). A maximum of six data logs are supported (up to two data logs when time comparison
mode is enabled). A maximum of two types of dimensionality are supported on the left and right
y axis. Samples are plotted on a date/time scale on the x axis. Samples in fault (due to
communication loss) are not plotted and will result in an interpolation gap within the plotted line.
If all samples are in fault, no line will be displayed.
