18 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

28 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.

29 FF defines two communication profiles, H1 and HSE. The H1 profile, with a transmission rate of 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.

30 In an 800xA environment a FOUNDATION Fieldbus network (FF network) is linked with the IEC 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.

31 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.

32 Device Management FOUNDATION Fieldbus consists of a set of software components for efficient planning, commissioning, and maintaining of field devices within ABB s Industrial IT 800xA system. The main components are: Fieldbus Builder FOUNDATION Fieldbus OPC Server FOUNDATION Fieldbus Device Library Wizard Device Type Objects

33 Fieldbus Builder FOUNDATION Fieldbus The FOUNDATION Fieldbus network and application configuration is done by the Fieldbus Builder FOUNDATION Fieldbus. It acts as an integrated application within the Industrial IT 800xA environment. The main tasks are: Managing the FOUNDATION Fieldbus network Creating FF Applications running on H1 links

34 Parameterization of field devices Generation of H1 schedules and configuration data for Link Active Scheduler (LAS) Managing device and function block libraries (this includes expanding the set of devices which are available as device type objects via import of Device Description files and Capabilities files) Download and commissioning Network and device diagnosis Configuration of OPC Server FOUNDATION Fieldbus
