<strong>CANopen</strong> <strong>Basics</strong><br />
7.5.1 PDO Mapping<br />
The functionality of a device equipped with a <strong>CANopen</strong> interface<br />
is described by the application object. Application<br />
objects are device parameters that can be either read or<br />
written, including but not limited to input and output values,<br />
speeds or further states.<br />
Every process data object can carry up to 8 bytes. Consequently,<br />
you need to define the positions within a PDO's<br />
data array. This definition or allocation is called a PDO<br />
mapping. It allows you to generate messages containing<br />
specific sets of information of a <strong>CANopen</strong> device. The<br />
communication profile range of the object dictionary contains<br />
the information about the PDO structure so that the<br />
structure is available via the network. If the allocation of<br />
application objects to a process data object permanently<br />
changes you would refer to it as dynamic mapping.<br />
