Siemens SIMATIC ET 200iSP

Grounding busbar EB
Terminal designation for electrical equipment operated in hazardous areas and connected to the
equipotential busbar.
GSD 󹪝le
All DP device-speci󹪝c properties are stored in a GSD 󹪝le (General Station Description). The format
of the GSD 󹪝le 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 (identi󹪝cation and maintenance data)
Identi󹪝cation and maintenance data (I&M) is information stored in a module.
Identi󹪝cation 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-speci󹪝c information such as the installation location and
date. M data is generated during con󹪝guration 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 󹪝eld 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.
