CANopen Slave Protocol Stack
Version 7.08.00
|
SDO and USDO services are mutually exclusive at run-time, but in CANopen FD mode (COS_FD_SUPPORT) the SDO API delegates value access to the USDO server, since the USDO protocol allows larger / FD-specific data handling. This header declares only the narrow set of USDO functions called from cos_sdo.c, so cos_sdo.c does not need to include the full cos_usdo_srv.h.
