Profiles
The communication profile
The CANopen communication protocol is based on a "communication profile", which
specifies the main communication mechanisms and their description (DS301).
The device profile
The most important types of devices used in industrial automation are described in
the "Device profiles". They also define device functionalities.
Here are some examples of standard devices:
Discrete and analog input/output splitter boxes (DS401)
Motors (DS402)
Control devices (DSP403)
Closed loop controllers (DSP404)
PLCs (DS405)
Encoders (DS406)
Device
Configuration via
the CAN Bus
The possibility of configuring devices via the CANopen bus is one of the basic
principles of the autonomy required by manufacturers (for each profile family).
