A/B slave
→Slave with an A or B being appended to its address number and which is
therefore allowed twice on
→the master.
Address
This is the "name" of the bus participant. All participants need a clearly defined
unique address so that the signals can be exchanged without problem.

Baud
Baud, abbrev.: Bd = unit of measurement for the data transmission speed. Do
not confuse baud with "bits per second" (bps, bits/s). Baud indicates the number
of changes of state (steps, cycles) per second over a transmission length. But it
is not defined how many bits per step are transmitted. The name baud can be
traced back to the French inventor J. M. Baudot whose code was used for telex
machines.
1 MBd = 1024 x 1024 Bd = 1 048 576 Bd
Bus

CAN is a priority-controlled fieldbus system for larger data volumes. It is
available in different variants, e.g. CANopen, CAN in Automation (CiA) or
→DeviceNet. CAN can be used e.g. as a supplier for AS-i over larger distances.
Corresponding

DeviceNet
Fieldbus system for larger data volumes based on
→CAN technology, requires
special cables, complex connection technology. Can be used e.g. as a supplier
for AS-i over longer distances. Corresponding
→gateways are available.

DHCP is a protocol which offers the dynamic configuration of IP addresses and
thus coherent information. The protocol supports use of IP addresses which are
only available in limited number by a centralised management of the address
assignment.
The participant logs onto a server with this service when it is switched on in a
network for the first time. The server assigns a local free IP address to the
participant.

ompatibility
According to the EC directive (89/336 EEC) regarding electromagnetic
compatibility (short EMC Directive) there are requirements regarding the capacity
of electrical and electronic equipment, installations, systems or components to
operate satisfactorily in the given electromagnetic environment. The devices
must not interfer with their environment and must not be negatively influenced by
external electromagnetic interference.
