Standardized profiles Standardized profiles describe objects that are used with different de- vices without additional configuration. The users and manufacturers or- ganization CAN in Automation has standardized various profiles. These include:
•DS301 communication profile
•DSP402 device profile

DS301 communication profile The DS301 communication profile is the interface between device pro- files and CAN bus. It was specified in 1995 under the name DS301 and defines uniform standards for common data exchange between different device types under CANopen.
The objects of the communication profile in the device carry out the tasks of data exchange and parameter exchange with other network de- vices and initialize, control and monitor the device in the network.
Objects of the communication profile are:
•Process Data Objects = PDO
•Service Data Objects = SDO
•Objects with special functions for synchronization SYNC and for error messages and error response EMCY
•Network management NMT objects for initialization, error monitor- ing and device status monitoring.
DSP402 device profile The DSP402 device profile describes standardized objects for position- ing, monitoring and settings of drives. The tasks of the objects include:
•Device monitoring and status monitoring (Device Control)
•Standardized parameterization
•Changing, monitoring and execution of operating modes IMPORTANT: The product does not support the CiA 402 device profile.
