The FOUNDATION Fieldbus Linking Device LD 800HSE EX is registered according to class 42c of the HSE profile, therefore providing the following functions:

• 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

In each of the four H1 channels the Linking Device operates as the Link Master as well as the SM Time Publisher.

Function

LD 800HSE EX is a highly compact gateway between four FF H1 links and FF HSE suited for redundant use. The linking device meets protection class IP20 and is DIN rack mountable. It is powered by 24 Vdc and supports Ethernet 10 Mbit/s and 100 Mbit/s.
