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