39 Glossary
Address
Unique number of a device connected to the network. With PROFIBUS this can
be 0 to 126. 127 is a broadcast address.
Analyzer
Software tool to observe the protocol traffic. Combi-Analyzers can also inspect
the signal quality.
Other term: Bus Monitor.
Example: ProfiTrace.
Bit Time (TBit)
To help simplify timing calculations, it is convenient to normalize the time units.
One Bit Time is the time it takes to transmit one bit and is the reciprocal of the
baudrate and is calculated as follows; TBit = 1 (bit) / baudrate (bps).
Examples:
12 Mbps --> TBit = 83 ns
1,5 Mbps --> TBit = 667 ns
C
Capacitance.
Class 1 master
A class 1 master is normally a PLC or DCS system. The class 1 master handles the
cyclical Data Exchange with the slaves assigned to it.
Class 2 master
A class 2 master is usually a laptop or programming console that is provided for
commissioning, maintenance or diagnostic purposes.
Data Exchange
The state of a slave after parameterization and configuration has been
completed, in which it cyclically exchanges I/O data with the master. Normally
the slave stays forever in Data Exchange until the bus communication or device
are stopped.
DGND
Digital Ground.
DIN
German Institute for Standardization (www.din.de).
DNS
Domain Name Service
When ComBricks is sending an e-mail, it uses a DNS server to look up the domain
name it is trying to access and convert it to an IP address. ComBricks uses a
default DNS server, but if your email server does not support this one, you can
enter an alternative DNS server.
DP-V0
DP-V0 is the basic stage of the PROFIBUS DP communication protocol. DP-V0
devices (master and slaves) perform the following basic functionalities:
Cyclic exchange of I/O data between controlling and slave devices
Device, Identifier (module) and Channel related Diagnosis
Parameterization of DP-slaves
Configuration of DP-slaves
