How to
Creating a Manual Trend Log
You create a manual trend log that records data that you manually enter.
The manual trend log records data that you manually enter. The manual trend log does not log a variable. Use this type of trend log when values from offline devices have to be manually registered to the trend log. For example, if you want to create a trend log that monitors an electricity meter that cannot be connected to the EcoStruxure BMS.
The default size of a manual trend log is 100 records.
