Figure 1-1. 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.
