Description

LD800HSE 3BDH000320R02

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 of the Linking Device
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
