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".
Marginalia
Marginal column beside a text used for notes and comments. Because of its
outstanding position well suited for quickly finding certain sections in the text.
Master
Handles the complete organisation on the bus. The master decides on the bus
access time and polls the
→
slaves cyclically.
Master-slave
communication
AS-i strictly operates to the master-slave principle. The master polls all slaves
one after the other in always the same order. Only one master per network line
is allowed (
→
cyclic polling).

DPV1
The DPV1 protocol is a communication protocol based on a
→
master/slave
architecture and was generated by Modicon* in 1979 for communication with
its PLCs. In the industry, DPV1 has become a de facto standard.
DPV1/TCP is based on
→
Ethernet TCP/IP. DPV1/TCP ports the protocol
defined for the serial interface to TCP. The
→
IP address clearly identifies each
unit a network. Therefore the slave address was used to identify one of several
logical units (unit IDs) in a physical device. To do so, extended IP addressing
is used.
Example: 192.168.83.28.1 means unit ID 1 on IP address 192.168.83.28.
*) Modicon passed from AEG to the Schneider group in 1994.

Password
In the menu [System Setup] in the menu item [Password] the operation can be
restricted or enabled. On delivery, the unit is in the user mode. By entering an
invalid password (e.g. 1000) all menu items which can change settings are
blocked.
