Connect the FBUS-HSE/H1 LD to the Fieldbus Network
The FBUS-HSE/H1 LD can be one of up to 32 devices connected to a
Fieldbus H1 network. The connection is made through one of the two 9-pin
male D-sub Fieldbus H1 connectors on the FBUS-HSE/H1 LD, shown in
Figure 2-4.
Use a Fieldbus cable with a 9-pin female D-sub connector to connect the
FBUS-HSE/H1 LD to a properly terminated Fieldbus network. When you
are using only an FBUS-HSE/H1 LD, the power hub is not being used for
power. For other Foundation Fieldbus devices that use bus powering, you
would apply power to the hub, from which devices would get their power.
Refer to the Fieldbus Foundation Wiring and Installation 31.25 kbit/s,
Voltage Mode, Wire Medium Application Guide for specific information
about wiring and installing a Fieldbus network. If you want to make your
own Fieldbus cable, refer to the Fieldbus Standard for Use in Industrial
Control Systems, Part 2, ISA-S50.02.1992. The FBUS-HSE/H1 LD
Fieldbus connector pinout is shown in Figure 2-6.
