Siemens SIMATIC ET 200iSP User Manual

CPU
Central Processing Unit > Central processing unit of an automation system.
Derating
Adjustment of the permissible ambient temperature depending on the air pressure (usually
corresponds to a speci󹪝c geographical installation position - elevation above sea level).
Device
A device can only exchange data after being requested to do so by the master. Devices are, for
example, DP devices - stations of the distributed I/O with PROFIBUS DP interface module. Master
and devices are only available for PROFIBUS.
Diagnostics
The detection, localization, classi󹪝cation, visualization and further evaluation of errors, faults
and messages.
Diagnostics provides monitoring functions which run automatically while the plant is in use. This
increases plant availability by reducing commissioning times and down times.
Distributed I/O systems
are input/output units that are not used in the central device but are con󹪝gured remotely by the
CPU of the automation system, for example:
• ET 200SP HA, ET 200M, ET 200X, ET 200L, ET 200S, ET 200iSP
• CFU
• DP/AS-I link
• Additional IO devices or DP devices from Siemens AG or other manufacturers
The distributed I/O systems are connected:
• As IO device via PROFINET IO with the IO controller of the CPU
• As DP devices via PROFIBUS DP with the DP master of the CPU
DP device
A device that is operated on the PROFIBUS with the PROFIBUS DP protocol and that behaves in
conformity with the standard IEC 61784-1:2002 Ed1 CP 3/1 is termed a DP device.
DP master
A master that behaves in conformity with IEC 61784-1:2002 Ed1 CP 3/1 is termed a DP master.
