<h2 id="mainmenu">Classes</h2>
<p>Objects are described by classes, and a Proview distributes contains several hundred classes
to configure a control system. You can also create your own classes in the
Class Editor. The classes can be data classes to store data, function object classes used
in the plc coding, or component or aggregates classes described below.</p>
<h2 id="mainmenu">Components and Aggregates</h2>
<p>A component is an object that controls a component in the plant, e.g. a valve, a contactor,
a temperatur sensor or a pump.
It can consist of
<ul>
<li> a main object with signals of the component.</li>
<li> a function object that contains the code.</li>
<li> a I/O object that configures the bus communication.</li>
<li> an object graph from which the operator handles the component.</li>
<li> a graphic symbol that is placed in an overview graph and shows the status of the component.</li>
<li> several methods to open trends, datasheet, photographs, circuit diagrams etc. for the component.</li>
<li> a simulation object to use for testing and simulation.</li>
</ul>
</p>
<p>Components can be combined to aggregate objects. One example is a
<a id="mainmenu" href="orm/basecomponent_basefcppo3pumpaggr.html" target="_blank">pump aggregate</a>
that contains a FrequencyConverter, a SafetySwitch, a Contactor, a CircuitBreaker, a Motor and
a Pump component.</p>

</p>
<p>Components and aggregates are highly configurable, and signals and components can be disabled, to match a
specific construction.
