Glossary
HSE device
Any device connected directly to High-speed Ethernet (HSE) media that
contains a conformant FOUNDATION fieldbus. HSE communication stack,
including a configurable network management agent. For example, linking
devices, I/O gateways, and HSE field devices.
HSE host Non-HSE device capable of communicating with HSE devices. For example,
configurators and operator workstations.
HSE linking device
Device used to interconnect FOUNDATION fieldbus H1 fieldbus networks
and/or segments to High-speed Ethernet (
HSE ) to create a larger system.
HSE switch Standard Ethernet equipment used to interconnect multiple High-speed
Ethernet (HSE) devices, such as HSE linking devices and HSE field devices to
form a larger HSE network.
IEC
Acronym for
International Electrotechnical Commission, which is a technical
standards committee that is at the same level as the ISO.
IEEE Acronym for Institute of Electrical and Electronic Engineers, which specifies a
family of standards for data communication over local and metropolitan
area networks.
input parameter
A block parameter that receives data from another block.
input/output subsystem interface
A device used to connect other types of communication protocols to fieldbus
segments.

ISA
Acronym for International Society for Measurement and Control.
interchangeability The capability to substitute a device from one manufacturer with that of another
manufacturer on a fieldbus network without loss of functionality or degree
of integration.
interoperability Capability for a device from one manufacturer to interact with that of another
manufacturer on a fieldbus network without loss of functionality.
IS
Abbreviation for intrinsic safety, a protection technique for safe operation of
electronic equipment in explosive atmospheres. The concept was developed for
safe operation of process control instrumentation in hazardous areas by making
sure that the available electrical and thermal energy in the system is always low
enough that ignition of the hazardous atmosphere cannot occur.
LAS
See
link active scheduler .
link
A logical link is a connection between function blocks; a physical link is a
connection between fieldbus devices.
