Siemens SIMATIC ET 200iSP Operating Instructions Manual page 467

Grounding busbar EB
Terminal designation for electrical equipment operated in hazardous areas and connected to the
equipotential busbar.
GSD file
All DP device-specific properties are stored in a GSD file (General Station Description). The format
of the GSD file is to be found in the IEC 61784-1:2002 Ed1 CP 3/1 standard.
HART
engl.: Highway Adressable Remote Transducer
Hot swapping
Pulling and plugging modules during the operation of the ET 200iSP.
I&M (identification and maintenance data)
Identification and maintenance data (I&M) is information stored in a module.
Identification data (I data): Information about the module that is normally printed on the
enclosure of the module. I data is read-only.
Maintenance data (M data): System-specific information such as the installation location and
date. M data is generated during configuration and written to the module.
I/O module
See electronic module
IO controller
Device used to address connected I/O devices. This means: The IO controller exchanges input
and output signals with assigned I/O devices. The CPU is often an IO controller. IO controllers and
IO devices are only available for PROFINET.
IO device
Distributed field device that can be assigned to one or more IO controllers (e.g. distributed I/O
system, valve terminals, frequency converters, switches). IO controllers and IO devices are only
available for PROFINET.
Isolated
For isolated I/O modules, the reference potentials of the control and load circuits are electrically
isolated, for example, by means of optical isolators, relays, or transformers. Input/output circuits
may be grouped.
