FP-3000 Network Module Description
The FP-3000 is an intelligent network interface and controller module that
manages a bank of up to nine FieldPoint I/O modules and terminal bases.
The FP-3000 network module and the terminal bases snap together to form
a high-speed data bus for communications between the FP-3000 network
module and any I/O modules in the bank. The FP-3000 includes an H1
Fieldbus interface for direct connection to an H1 F
O U N D A T IO N
Fieldbus link
(also known as a segment). Refer to the F OUNDATION Fieldbus Overview
document for more information on F O U N D A T IO N Fieldbus. Under the best
circumstances, you can connect at most 32 FP-3000 network modules to a
single F
O U N D A TIO N Fieldbus link (without repeaters). The actual number of
FP-3000 network modules that can be connected depends on your network
setup and your applications.
The FP-3000 network module allows you to bring conventional analog and
discrete I/O devices onto a F
O U N D A TIO N Fieldbus network. 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
