CAN

Lower layer CAN protocol for upper layer CAN protocols like CAN OPEN,
J1939 and device net-

CAN open

Upper layer protocol for CAN networks

CIA

CAN in Automation, CAN open standardization organization
(www.canorg.net)

CAN ID

ID of the CAN message seen on the bus. Consist of 11 or 29 bits. Part of the
COB Ids which can be found in object dictionary

COB ID

Consists of CAN ID and some control and informative bits. Found in object
dictionary.

Note that in older communication specifications both the CAN

ID and COB ID were named as COB ID!

Object

Variable which is accessable through CAN interface

Object Dictionary

Consists of objects, Accessable from CAN bus with SDO writ and read
operations
