Member Data Documentation

BitLen

uint16_t TETHERCAT_SDO_INFO_ENTRY::BitLen

Bit length of the entry value.

DataType

uint16_t TETHERCAT_SDO_INFO_ENTRY::DataType

Data type index of this entry (refer to CoE data type index table).

Index

uint16_t TETHERCAT_SDO_INFO_ENTRY::Index

Object index of the entry being described.

ObjAccess

uint16_t TETHERCAT_SDO_INFO_ENTRY::ObjAccess

Access rights bitmask: bit 0 = read, bit 1 = write, bit 2 = const, bit 3 = PRE-OP, bit 4 = SAFE-OP, bit 5 = OP.

[struct]

struct { ... } TETHERCAT_SDO_INFO_ENTRY::Res

Response payload with entry type and access metadata.

SubIdx

uint8_t TETHERCAT_SDO_INFO_ENTRY::SubIdx

Sub-index of the entry within the object.

ValueInfo

uint8_t TETHERCAT_SDO_INFO_ENTRY::ValueInfo

Bitmask of which optional fields are present in Res: bit 0 = ObjAccess, bit 1 = ObjCategory, bit 2 = PdoMapping, bit 3 = UnitType, bit 4 = DefaultValue, bit 5 = MinValue, bit 6 = MaxValue.
