What is a fieldbus?the fundamental task of a fieldbus system is to exchange
information
in a digital way
with less wiring (unlike point to point connections )
with a number of participants
in a safe way (communication layers)
fast (real-time)

Requirements of process industry
Requirements of the process industry for a fieldbus system
open and standardized
robust and easy technology
high degree of freedom to chose
exchange and connection of new devices during operation
to be used in hazardous areas (Eex)
offer additional information as diagnosis …..

HSE physical layer
defined by the IEEE 802.3 specifications
100 Mbit/s
HSE uses two Ethernet transport protocols to send data over the network
100BASE-T: two pairs of high-quality twisted-pair wires
100BASE-F: fiber optic cables
In each case, the length of a twisted-pair segment may be up to 100 meters (328 feet). Possible to expand with repeaters

Installation and commissioning
Field devices and components: Less cable (shorter stub lines)Fewer switching cabinets and control boxesParameterization from the control room
Decentralized Control System:Fewer components eliminates possibilities for errorsField device diagnostics, suppy detailed causes of error and malfunction (error transparency)

Maintenance and inspection
Reduction of plant stoppage times because:Detailed diagnostics data from the devices!Device exchange via Plug&playFunctionality uploads/downloads when device is exchangedNo dismantling of devices purely“on suspicion”Multivariable devices offer substitute values when a device fails

Device identification
Each device also have a user-definable tag name.There are 32 characters available for assigning tag names to a
deviceThis tag name becomes a reference name for the Host system or
configuration tools
My name is:
