1.1 Features of the Linking Device
The LD 810HSE Ex 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 Link Master as well as 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
