MAC = M anufacturer‘s A ddress C ode
= manufacturer's serial number.
→ID =
Id entifier
Every network card has a MAC address, a clearly defined worldwide unique numerical code, more or
less a kind of serial number. Such a MAC address is a sequence of 6 hexadecimal numbers, e.g. "00-
0C-6E-D0-02-3F".

MRAM = M agnetoresistive R andom A ccess M emory
The information is stored by means of magnetic storage elements. The property of certain materials is
used to change their electrical resistance when exposed to magnetic fields.
Advantages of MRAM as compared to conventional RAM memories:
• non volatile (like FRAM), but:
• access time only approx. 35 ns,
• unlimited number of access cycles possible.

NMT
NMT = N etwork M anagemen t = (here: in the CANopen protocol).
The NMT master controls the operating states of the NMT slaves.

Node
This means a participant in the network.

Node Guarding
Node = here: network participant
Configurable cyclic monitoring of each
→slave configured accordingly. The →master verfies if the
slaves reply in time. The slaves verify if the master regularly sends requests. In this way failed network
participants can be quickly identified and reported.
