Terms and abbreviations
0b ... binary value (for bit coding), e.g. 0b0001 0000
0x ... hexadecimal value, e.g. 0x64 (= 100 decimal)
Baudrate transmission speed (1 baud = 1 bit/s)
CAL CAN Application Layer
CAN-based network protocol on application level
CAN Controller Area Network (bus system for use in mobile applications)
CAN_H CAN-High; CAN connection /cable with high voltage level
CAN_L CAN-Low; CAN connection /cable with low voltage level
CANopen CAN-based network protocol on application level with an open configura-
tion interface (object directory)
CiA "CAN in Automation e.V."
(user and manufacturer organisation in Germany /Erlangen)
Definition and control body for CAN and CAN-based network protocols
CiA DS Draft Standard (published CiA specification which usually has not been
modified or supplemented for one year)
CiA DSP Draft Standard Proposal (published CiA specification draft)
CiA WD Work Draft (work draft accepted for discussion within CiA)
CiA DS 301 Specification for CANopen communication profile;
describes the basic communication between network participants, such as
the transfer of process data in real time, the exchange of data between
units or the configuration stage. Depending on the application this is com-
pleted by the following CiA specifications:
CiA DS 401 Device profile for digital and analog I/O modules
CiA DS 402 Device profile for drives
CiA DS 403 Device profile for HMI
CiA DS 404 Device profile for measurement and control technology
CiA DS 405 Specification for interfaces to programmable systems (IEC 1131)
CiA DS 406 Device profile for encoders
CiA DS 407 Application profile for local public transport
COB CANopen Communication Object (PDO, SDO EMCY, ...)
COB ID CANopen Identifier of a Communication Object
Communication cycle the synchronisation time to be monitored, max. time between 2 Sync
objects
EMCY Object Emergency Object (alarm message, device indicates an error)
Error Reg Error Register (entry with an error code)
Guarding Error Node or network participant could or can no longer be found
Guard Master: one or several slaves no longer reply
Guard Slave: no polling of the slave
Guard Time During this time the network participant expects a "Node Guarding" of the
network master
Heartbeat Cyclic monitoring with parameter setting among network participants.
In contrast to "node guarding" no superior NMT master is required.
ID Identifier; identifies a CAN message. The numerical value of the ID also
contains a priority for the access to the bus system
ID 0 = top priority
Identifier see ID
Idx index; together with the S index it forms the address of an entry in the
object directory
Life Time Factor number of attempts in case of a missing Guarding reply
Monitoring is used to describe the error class (guarding monitoring, synch etc.)
NMT network management
NMT master/slaves The NMT master controls the operating states of the NMT slaves
Node Guarding adjustable cyclic monitoring of slave network participants by a higher
master node as well as the monitoring of this polling process by the slave
participants
