FouNDATIoN Fieldbus Linking Device

LD 800HSE

LD 800HSE serves as a gateway between High

Speed Ethernet (HSE Subnet) and the FOUNDATION

Fieldbus field devices on H1 links. The provision of

data from a H1 link to the HSE Subnet, as well as

from one H1 link to another, is guaranteed by the

communication – typical of FOUNDATION Fieldbus –

between field devices on various H1 links and field

devices on the HSE Subnet. In addition, the client/

server gateway allows function blocks in H1 devices

to be accessed via the HSE interface. LD 800HSE is

also designed for redundancy.

other fieldbus devices

To protect the fieldbus segment and the links, the

Fieldbus Barrier FB 900 series can be used. The PC

900 Power Conditioner provides a higher supply

current for a H1 link. These devices are described
