Item Description
1 RSFieldbus workstation
2 24V DC power supply
3 Linking device - 1757-FFLD or 1757-FFLDC

Figure 5 shows an example of a typical fieldbus system. The HSE protocol is
established during the initial download of the RSFieldbus software. Data is
transferred and stored to the workstation through the Ethernet or ControlNet
networks depending on your application requirements and the selected
linking device.
The 1757-FFLD linking device connects field devices on H1 segments to Logix
controllers by using an Ethernet transmission. The 1757-FFLDC bridges data
flow between H1 segments on the ControlNet network.

You must have at least one power conditioner per power supply on the H1 line,
and two terminators; one each at opposite ends of the bus, as shown in
Figure 9.
