A trend log is a collection of time-stamp values. In WebStation, you can create a trend log from a value.

Interval Trend Logs

​The interval trend log collects data at a specific time interval. Each logged value is stored as a record in the trend log. Use this trend log when the logging interval is less than 1 hour.

For more information, see Interval Trend Logs .

Extended Trend Logs

​You use an extended trend log to transfer records from a trend log. An extended trend log can be connected to a trend log or connected in a series to another extended trend log. Only one extended trend log can be connected to a trend log.

For more information, see Extended Trend Logs .

Log Record Storage

​All trend logs use circular storing. How many records a trend log can store before overwriting old ones depends on the trend log configuration.

For more information, see Log Record Storage .

Meter Function

​The meter function adds meter properties to any trend log type to seamlessly handle consumption calculations independent of meter rollover or meter exchange.

For more information, see Meter Function .
