CiA 453: CANopen device profile power supply
The CANopen device profile for power supplies supports up to eight power outputs. It is suitable for programmable and non-programmable power supplies. It provides sophisticated failure indication and reporting capabilities. The profile supports AC/AC, AC/DC, DC/AC, and DC/DC converter. Most of the process and configuration parameters are optional. The finite state automaton (FSA) for power input and power outputs are similar and loosely coupled.
The profile pre-defines four TPDO and four RPDOs. The RPDOs contain the output 1 command and set values for voltage, current, and power. The TPDOs transmit the output 1 status and actual output 1 values (voltage, current, and power). If the device designer implements application-specific PDOs instead of the pre-defined, this is indicated in the device type object.
Heartbeat is mandatory. Additional Emergency error codes are defined and it is recommended to support the Emergency producer service. If necessary, you may implement up to eight instances (logical devices) of CiA 453 in one CANopen device, which would result in up to 64 power outputs implemented in one CANopen device.
