FOUNDATION fieldbus was originally intended as a replacement for the 4-20 mA standard.
Foundation Fieldbus is an all-digital, serial, two-way communications system that serves as the base-level network in a plant or factory automation environment
A typical fieldbus segment consists of the following components.H1 - fieldbus interface card FPS - Fieldbus Power Supply and Signal Conditioner PS - Bulk power (Vdc) to Fieldbus Power Supply T - Terminator And fieldbus devices, (e.g. transmitters, transducers, etc

INTRODUCTION
FOUNDATION Fieldbus (FF) is a fieldbus protocol based on
international standards and designed for applications in the manufacturing industry, process automation and
buildings automation. The guidelines for this fieldbus standard are published by the Fieldbus Foundation.

FF defines two communication profiles, H1 and HSE. The H1 profile, with a transmission rate of 31.25 kilobits per second,
is preferably used for direct communication between field
devices in one link (H1 link). The HSE profile, which is based on standard Ethernet and typically features a transmission
rate of 100 megabits per second, serves first and foremost as a powerful backbone for the connection between H1 links. The devices that are already available on the market and support the HSE profile are FF linking devices. They serve as
a gateway between the field devices on the H1 links and the
HSE backbone. Device Management FOUNDATION Fieldbus supports the ABB Linking Device LD 800HSE.

In an 800xA environment a FOUNDATION Fieldbus network (FF network) is linked with the IEC 61131 controller via a
FOUNDATION Fieldbus HSE communication interface
module CI860 in the AC 800M; this module is installed as an HSE host on the powerful HSE subnet.

ADVANTAGES:
FOUNDATION Fieldbus provides an open standard for process automation applications and is supported by all the major control and automation product manufacturers. It consists of a low-speed bus (H1) designed for the interconnection of “field” equipment such as sensors, actuators, and I/O, and a high-speed bus (HSE, High Speed Ethernet) allowing optimization of network design and integration of high speed controllers (such as PLC or DCS), H1 subsystems (via linking devices), data servers and workstations. FOUNDATION Fieldbus provides built-in capability to distribute the control application across the network.
