Glossary
Configuration
The systematic arrangement of the different ET 200S modules (setup)
Device database file
A device database file contains all the DP slave-specific properties. The format of
the DDB file is defined in IEC 61784-1:2002 Ed1 CP 3/1.
Diagnostics
Diagnostics involves the identification, localization, classification, display, and
further evaluation of errors, faults, and messages.
Diagnostics includes monitoring functions that run automatically while the system
is in operation. This increases the availability of systems by reducing setup times
and downtimes.
Direct-on-line starter
A direct-on-line starter is a ³ motor starter that switches a motor on or off directly.
It consists of a circuit breaker and a contactor.
Distributed I/O systems
These are input/output units that are not located in the base unit; instead, they are
distributed at some distance from the CPU. The following are examples of such
units:
S ET 200M, ET 200X, ET 200L, ET 200S
S DP/AS-i Link
S S5-95U with PROFIBUS-DP slave interface
S Other DP slaves from either Siemens or other vendors
The distributed I/O systems are connected to the DP master by means of
PROFIBUS-DP.
DP master
A ³ master that complies with IEC 61784-1:2002 Ed1 CP 3/1 is known as a DP
master.
DP slave
A ³ slave running on the PROFIBUS on the basis of the PROFIBUS-DP protocol
in accordance with IEC 61784-1:2002 Ed1 CP 3/1 is known as a DP slave.
