Glossary

AC or DC drives
AC or DC motors.
AI
Please see Analogue input.
Analogue input
Analogue input, detects analogue signals as voltage
signals from 0 to 10 V or as current signals from 0
to 20 mA or 4 to 20 mA; resolution is generally 10 or
12 bit, 16 bit representation.
Analogue output
Analogue input, control variable as analogue signal;
voltage signals from 0 to 10 V or -10 V to +10 V or
as current signals from 0 to 20 mA or 4 to 20 mA;
resolution is generally 10 or 12 bit, representation
16 bit representation.
AO
Please see Analogue output.
AUX IN
Power supply, 24 V DC feed in
AUX OUT
Power supply, 24 V DC feed out
Baud rate
The baud rate describes the number of signal codes
(symbol) that can be transmitted per second.
Bus / power section
The section on the SAI to which the Fieldbus and
the supply voltage are connected.
Bus termination
Install the bus terminations at the physical begin-
ning and physical end, according to the CANopen
standard ISO11989 using the following values: An
active bus termination must be fitted at the begin-
ning and end of each CAN-bus segment, according
to CANopen-Norm ISO11898.
CAL
CAN Application Layer. Application layer (ISO/OSI
layer 7) as specified by the CiA.
CAN
Controller Area Network.
170
CiA
CAN in Automation - the organization of the CAN-
bus device manufacturers and users
CiA Draft Standard 102
Description of the physical CAN communications
(level 2) for industrial applications.
CiA Draft Standard 301
Description of the application and communication
profile for industrial systems.
CiA Draft Standard 401
Description of the device profile for general input
and output modules.
CMS
CAN-based Message Specification A service ele-
ment which makes the application level available for
object manipulation.
COB
Communication Object Messages are sent on the
network as COBs and dealt with as communication
objects.
COB-ID
COB Identifier Each communications object is iden-
tified by a unique COB-ID.
The COB-ID indicates the priority of the communi-
cations object.
Coding A
Special coding for male or female M12 connectors
for purposes of recognition and non-reversal. On
SAI modules, coding A is utilised for the power sup-
ply as well as inputs and outputs. DeviceNet and
CANopen Fieldbus systems have also specified the
A-coded version.
Coding B
Special coding for male or female M12 connectors
for purposes of recognition and non-reversal. Cod-
ing B is used for the PROFIBUS-DP Fieldbus.
Configuration

Configuration menu
This is used to enter and configure the hardware of
a control system.
