Terms and
Abbreviations Used in
This Guide
CAN Controller Area Network.
CiA CAN in Automation International Users and Manufacturers Group.
CMS CAN Message Specification; one of the service elements of the CAN
Application Layer in the CAN Reference Model.
COB Communication Object; a unit of transportation on a CAN network.
Data is sent across a network inside a COB. The COB itself is part of
the CAN message frame.
Communication Module Communication Module (often abbreviated COMM. MODULE or
COMM.) is a parameter name/parameter selection name for a device
(e.g. a fieldbus adapter) through which the drive is connected to an
external serial communication network. The communication with the
communication module is activated with a drive parameter (see the
drive documentation).
Data Sets and
Data Words
Data sets are clusters of data sent through the DDCS link between the
NCAN-02 Adapter Module and the drive. Each data set consists of
three 16-bit words, i.e. data words. The Control Word (sometimes
called the Command Word) and the Status Word, References and
Actual Values (see Chapter 6) are types of data words; the contents of
some data words are user-definable.
DBT Distributor; one of the service elements of the CAN Application Layer in
the CAN Reference Model. It is the responsibility of the Distributor to
distribute COB IDs to the COBs that are used by a CMS.
EDS Electronic Data Sheet; a node-specific ASCII-format file required when
configuring the CAN network. The EDS file contains general
information on the node and its dictionary objects (parameters). EDS
files for ABB drives are available through your local ABB
representative. A listing of an EDS file can also be found in Chapter 5.
LMT Layer Management; one of the service elements of the CAN
Application Layer in the CAN Reference Model. It serves to configure
parameters for each layer in the CAN Reference Model.
