Configuring a Manual Trend Log
You configure the properties of a manual trend log to meet the unique needs of your site.
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.
A manual trend log can be created with initial meter settings. The manual trend log supports the meter change command and meter consumption calculation. You can view the last meter change information on the manual trend log object. Pour plus d'informations, voir Meter Function .
