fieldbus systems
The Rosemount 2230 Display supports the FOUNDATION fieldbus (FF)
technology and lets you integrate a 2230 into an existing FF network. As long
as the power supply meets certain requirements (see Figure 3-5 and
Figure 3-6) the 2230
(1)
will be able to operate as any other FF device.
Figure 3-5. Example of an I.S.
FOUNDATION fieldbus system
Ensure that the power supply is able to provide the total current needed for all
the connected devices. See “Power Requirements” on page 3-7 for further
information.
Ensure that the 2230 and other devices connected to the FOUNDATION
fieldbus (FF) system are compliant with the FISCO or Entity parameters of the
power supply.
Ensure that the short circuit protection of the Segment Coupler
(2)
matches the
current consumption of the connected devices.
