cos_usdo_srv.h File Reference

Detailed Description

USDO services are intended for configuration and diagnostic tasks in CANopen FD systems. Nevertheless process data can be transferred via USDO services as well. The USDO service offers confirmed communication between one USDO client and one or several USDO servers. By means of the USDO protocol the USDO client has access to CANopen FD object dictionary entries supported in the CANopen FD devices in the network. The USDO services provide read and write access to sub-indexes in the USDO servers’ object dictionary (see cos_dict.h).

USDO services allow the transfer of any data size between the USDO client and the USDO server. The inherent routing capability of the USDO services enables data transfer over CANopen FD network borders; USDO client and USDO server are not necessarily connected to the same CAN.

The functions in this module are called by the CANopen slave manager on reception of a USDO request.
