====================================
VOLTTRON Central Management Overview
====================================

VOLTTRON Central is responsible for controlling multiple VOLTTRON instances with a single management instance.
The managed VOLTTRON instances can be either local or remote. Each managed instance will have a VOLTTRON Central
Platform agent installed and running to interface with the primary VOLTTRON Central agent.

|VC-VCP Overview|

There is a :ref:`VOLTTRON Central Deployment Demo <VOLTTRON-Central-Deployment>` that will allow you to quickly setup
and see the current offerings of the interface.

VOLTTRON Central will allow you to:

    * See a list of platforms being managed.
    * Add and remove platforms.
    * Install, start and stop agents on the managed platforms.
    * Create dynamic graphs from the historians based upon data points.
    * Execute functions on remote platforms.


Volttron Central Agent
======================

The VOLTTRON Central (VC) agent serves a web-based management UI that interfaces with the
VOLTTRON Central web API.


VOLTTRON Central Platform Agent
===============================

The VOLTTRON Central Platform (VCP) Agent allows communication with a VOLTTRON Central instance.
Each VOLTTRON instance managed by VOLTTRON Central should have only one Platform Agent.
The Platform Agent must have the :term:`VIP Identity` of `platform.agent` which is specified as default by VOLTTRON
:ref:`known identities <VIP-Known-Identities>`.
