Information Reason for return
If possible, the reason for returning the component/device should be stated. If necessary, at least one contact for
queries should be stated.
This is important in order to keep repair times as short and efficient as possible.
On request you can also obtain a suitable return goods voucher from Getriebebau NORD.
Unless otherwise agreed, the device is reset to the factory settings after inspection or repair.
ATTENTION Possible Consequential Damage
In order to rule out the possibility that the cause of a device fault is due to an optional module, the connected
optional modules should also be returned in case of a fault.

ASIC Integrated circuit specific to the application
Baud rate The transmission rate for serial interfaces in bits per second
Binary code The designation for a code in which messages are communicated by "0" and "1" signals.
Bit / Byte A bit (binary digit) is the smallest unit of information in the binary system. A byte consists
of 8 bits.
Broadcast In a network, all slave participants are addressed simultaneously by the master.
CAN Controller Area Network is an asynchronous serial field bus system
CANopen Designates a communications protocol based on CAN
COB - ID Communication Object Identifier à Identifier of a CAN/CANopen message
EDS Electronic Data Sheet
EMCY message Emergency message (error telegram)
Little Endian Describes the sequence in which the bytes are processed in a data word. In this case
first the Low byte and then the High byte
Identifier Unique definition of a message ("addressing") à Address of a CAN message box (i.e.
addressing of a message and not the participant); a node may have several identifiers.
ISO The International Standards Organisation is the international association of
standardisation organisations and produces international standards in all fields, with the
exception of electricity and electronics.
Node Bus participant, e.g. an FI, I/O module, etc.
OSI layer model The Open Systems Interconnection Reference Model (OSI) defines the elements,
structures and tasks necessary for data communication and assigns these to the times
for the communication process in seven consecutive layers.
Polling Cyclical querying of individual components by a central component (NMT master / NMT
slave)
Producer-consumer
model A participant (producer) places data on the bus, all other participants (consumers)
receive this message and decide on the basis of the identifier, whether this message is
relevant to them.
