CANopen device and application profiles
The set of CANopen specifications also includes device and application profiles. Generic and specific device profiles specify the interface of a logical device. Application profiles describe a set of virtual device interfaces. A CANopen device may implement one or several virtual devices.
A network that is just made up of unconfigured devices that comply to device profiles is normally a pure master/slave system with respect to PDOs. A network with CANopen devices that comply to an application profile, provides pre-defined intercommunication between the devices.
In both approaches (device and the application profile) the system designer is able to reconfigure the default behavior in order to tailor the network communication to the system requirements.
CANopen interface profiles are specified for devices with no application functionality (e.g. non-transparent gateways). Interface profiles may be regarded as specific device profiles featuring proxy functions.
In general, standardized profiles simplify system integration by means of off-the-shelf configuration tools. Devices compliant to the same profile are interoperable and partly or completely exchangeable.
