Command Handler, DTLCCMDH

Condense, DTLCCNDS

The following table describes the main functions of each PowerExchange Condense task and subtask:

Task	Description
Controller	Manages startup, error handling, cleanup, and the running of subtasks.
Command Handler	Handles the processing of commands and the command interface.
Condense	Periodically performs condense processing.

The communication among the tasks is handled by using an internal process event mechanism.
