8. MainDevice Object Dictionary

M/O/C: Mandatory, Optional, Custom

A/F/C: Available (implemented in EC-Master), Forceable (EC_IOCTL_MASTEROD_SET_VALUE), SDO Complete Access

The following Object Descriptions contain all Object Entries, even if some of the Object Entries are not implemented in EC-Master. This is needed for Complete Access. Using Complete Access, all Object Entries of an Object can be transferred at once. The corresponding C structs for Complete Access are defined in SDK/INC/EcInterfaceCommon.h, e.g. Object 0x2002 “Bus Diagnosis Object” is structured as EC_T_OBJ2002.

The MainDevice additionally provides the ENUM description object 0x0800 in the data type area (0x0000-0x0FFF). It is required by the CoE Information Services, is read-only and carries the two entries “Signed presentation” (0x0800:01) and “Unsigned presentation” (0x0800:02). Applications do not need to access it.
