Fieldbus Network Setup
The FP-3000 network module provides a Fieldbus interface to conventional
analog and discrete I/O devices. For example, the FP-3000 makes a
4–20 mA pressure transmitter connected to a FieldPoint 8-channel analog
input module behave like a Fieldbus pressure transmitter. By using an
FP-3000 network module, you can significantly reduce wiring and
installation costs. Instead of running a pair of wires from each 4–20 mA
device to your controller, you can mount an FP-3000 network module in the
field and run a single pair of wires (called the trunk) from your PC to the
FP-3000. You connect the 4–20 mA devices to the FieldPoint I/O modules
by short stretches of wire.
