Glossary

ATQA

The ATQA (Answer To reQuestA) is used to
identify the ID tag type.

CAN

Controller Area Network, bus system for
use in mobile applications.

CANopen

CAN-based network protocol on the
application level with an open configuration
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.

COB

CANopen communication object (PDO,
SDO, EMCY, ...)

EDS

Electronic data sheet

EMCY

The emergency object contains an alarm
message with which the device signals an
error.

Heartbeat

Configurable cyclic monitoring among
network participants. In contrast to "node
guarding" no superior NMT master is
required.

ID tag

An ID tag is used to identify objects. A read/
write device is used to read the ID tag via a
high-frequency radio signal. An ID tag
consists of an antenna, an analogue circuit
for receiving and transmitting (transceiver),
a digital circuit and a non-volatile memory.

LSS

Procedure to set basic device settings

NMT

Network management

Node ID

Unambiguous number of a participant in the
CANopen network.

Object

Term for data/messages which can be
exchanged in the CANopen network.

PDO

The Process Data Object transmits process
data in real time in the CANopen network,
for example the speed of a motor. PDOs
have a higher priority than SDOs; in
contrast to the SDOs they are transferred
without confirmation. PDOs consist of a
CAN message with identifier and up to 8
bytes of user data.

PDO mapping

Describes the application data transferred
with a PDO.

RPDO

Process data object received from the
device.

RSSI

The Received Signal Strength Indication is
the field strength of the received signal.

SDO

The SDO directly accesses the object
directory of a network participant (read/
write). An SDO can consist of several CAN
messages. The transfer of the individual
messages is confirmed by the addressed
participant. With the SDOs, devices can be
configured and parameters can be set.

SYNC

The SYNC telegram initiates the
synchronised transmission of process data.

TPDO

Process data object sent by the device.
