HXAM_G_Available_Logs_FE is not actually used for logging, but displays the
values for which logs are configured on the default Heat Exchanger object type

(3BSE030322*) for more details.

History Source

The History Source Aspect is used to define the Service Group that handles a subset
of logs, i.e. the Log Configurations on all child objects. It should be noted that if no
History Source is defined no logging will occur.

Log Template

A Log Template is a template for building logs for heat exchanger properties.
Modifying the Log Template will affect existing logs that use the Log Template.
The template is configured to log data for the last three years.

Log Configuration

The Log Configuration Aspect is used to configure what properties are to be logged.
In the Generic Heat Exchanger Asset Monitor the following properties are
configured to be logged:
