LD 800HSE EX ABB 3BSE073314R1 FOUNDATION Fieldbus Linking Device

Description:

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 kbit/s, 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 Mbit/s, serves first and foremost as a powerful backbone for the connection between H1 links. The first 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 subnet

Features

The LD 800HSE is a gateway between an FF High Speed Ethernet (FF-HSE) subnet and FF-H1 links. It supports device redundancy.

The linking device is registered as class 42c of the HSE profile, therefore providing the following functions:

• It supports up to four separate galvanically isolated FF-H1 links. In each of these links, the linking device operates as the Link Master as well as the SM Time Publisher
• Identification of devices connected to the H1 links
• Configuration of connected H1 devices through System Management and Network Management via HSE
• Access to the function blocks of connected H1 devices via HSE
• Republishing of process data between H1 links
• Republishing of process data from H1 to HSE and vice versa

• Distribution of alarms and events sent by H1 devices

For System 800xA SV5.1 onwards, LD 800HSE supports multi user engineering. It allows concurrent configuration and commissioning via several parallel sessions:

• Configuration and commissioning: One H1 link allows configuration and commissioning for one client of the Fieldbus Builder FOUNDATION Fieldbus. This can be done with as many clients as H1 links are available per subnet.

• Parameterization: An unlimited number of users is possible here allowing a quasi-parallel access to single block parameters. In all situations, LD 800HSE ensures a consistent configuration and operational status without limitations to its redundancy status.
