The CAN in Automation (CiA) organization has released the last part of the reviewed CiA 302 series of additional application layer functions. Part 3 specifies the configuration manager and the program download via the CANopen network.
The other parts of CiA 302 were released earlier and specify the network management including the NMT flying master (part 2), the network variables and the process image (part 4), the SDO manager (part 5), bus-line (network) redundancy (part 6), and multi-level networking (part 7).
“The completion of the CiA 302 version 4.1 is an important milestone,” said Holger Zeltwanger, CiA Managing Director.
The program download is an additional application layer function and the specification provides also hints for boot-loader persistence, access protection, and compatibility checks.
