CAN Controller Area Network
Communication
COB Communication objects (COBs) carry data and can be transmitted through
the whole network. A COB is part of a CAN message frame.
Electronic datasheet, an ASCII file for node configuration, required when a
EDS CANopen network is configured. An EDS file contains general information
about nodes and their dictionary objects (parameters).
Network management, one of the CAN application-layer service elements in
NMT the CAN reference model. It is used for the initialization, configuration, and
fault handling of a CAN network.
Object
Stores information about all COBs identified by a device.
dictionary
Process data object, a type of COBs, used to transmit process data, such as

refers to 1, 2, 3, 4.
PDO command transmitted by the master station and received by a slave
PDOn Rx
station, where n refers to 1, 2, 3, 4.
Service data object, a type of COB, used to transmit non-time key data, such
SDO

RO Indicates read-only access.
RW Indicates the read and write access.
SYNC Indicates synchronous transmission.
Node-ID Node ID, that is, address of a communication card.
Indicates that a number with this prefix is a hexadecimal value, for example,
