FP-1000 and FP-1001

Chapter

Network Module Overview

This chapter prov ides an o ve rview of the Fie ldPoin t ne twork mo dules .
The FP-1000 FieldPoint network module connects an industrial RS-232

network to FieldPoint I/O modu les. The FP-1001 Fiel dPoint ne twork
module connects an industrial RS-485 netwo rk to FieldPoint I/O
modules.

The FP-1000 and FP-1001 support stan dard co mmands (subs et of
Optomux command set), and a set of extended commands to completely
support the FieldPoint I/O modules. Both network modules can co-exist
with other Optomux devices on the same network.

The FP-1000 and FP-10 01 use the Op tomux p rotocol. The refor e, a f ter
you have configure d the FieldPoin t ba nk ( ne twork mod ule a nd I/O
modules), you can use any application software that supports Optomux
to communicate wi th Field Point m od ules in the ba nk.

In a distributed application, many FieldPo int ba nks a re n etwor ked
together. You can netw ork up to 25 FieldPoi nt bank s to each
RS-232/RS-485 port of y our ho st c ompute r. Eac h ban k ca n c ont ain up
to nine I/O modules, thus connecting up to 225 I/O modules per RS-232
(or RS-485) port in your host co mpu ter. You c an furth er in cr ease you r
field I/O count by using more RS-232/RS-485 por ts in your host
computer.

FP-1000 Connects to RS-232

The FP-1000 connec ts dir ectly to the RS- 232 p ort that is a vailable on
most host computers. Since RS-232 is a point-to-poin t network that
allows connection to only one device, the FP-1000 provides an RS-485
repeater so that you can build a network with multiple FieldPoint banks.

National Instruments Corporation 1-1 FieldPoint FP-1000/FP-1001 User Manual

Chapter 1 FP-1000 and FP-1001 Network Module Overview

FP-1001 Connects to RS-485

The FP-1001 FieldPoint netw ork modu le co nnects dire ctly to an
RS-485 adapter card that is installed in your host computer. Since
RS-485 is inherently a multidrop n etwork , the FP-1001 do es not
provide a separate RS-485 repeater. You can network multiple FP-1001
modules in multidrop fashion.

The FP-1001 communicates over RS-485, utilizing full-duplex mode. It
is optically isolated, which prevents fault coupling between the RS-485
network and the FP-1001.

Configuration

This chapter describes how to insta ll a nd co nfig ure y our FieldP oint
network module, connect it to an RS-232 or RS-485 network, a nd
connect power to the netwo rk module.

Installing the Network Module

The FieldPoint network m odule s ha ve rugge d, simple clips fo r
mounting reliably onto a standard 35 mm DIN rail. Follow these step s
to mount the network module onto a DIN rail. Terminal ba ses must be
connected to the network module before power is applied.

1. Use a flat-bladed screwdriver to open the DIN rail clip to the
unlocked position, as shown in Figure 2-1.

Figure 2-1.

2. Hook the lip on the rear of the network module onto the top of a
35 mm DIN rail and press the ne twork module down onto the DIN
rail as shown in Figure 2-2.

Removing the Network Module

To remove a network module, unlock it from the DIN rail by placing a
screwdriver in the slot on the rail snap a nd o pen ing it to th e unloc ked
position as shown in Figure 2-1. T hen d isco nnect the termina l b ase
from the network module’s local bus connector, and lift the module off
of the rail.

Connecting Terminal Bases

Follow these steps to connect a terminal base and a network module.

Note: Ensure that power is not applied to the network module, before you install

or remove terminal bases.

1. Remove the protective cover from the network module’s local bus
connector (see Figure 2-2).

2. Install the terminal base onto the DIN rail in the same way you
installed the network module. Refer to the operating instructions
for the FP-TB-1/2 more information on how to install your terminal
base onto the DIN rail.

4. To add more terminal bases, install them on the rail and mate their

described in the RS-232 In terface Specification s and RS-485 Inte rface
Specifications sections later in this chapter.

Connect the RS-232 por t of the FP-10 00 to y our ho st c ompute r’s
RS-232 port. Use a 9-pin Dsub male-to- female “ straight-thr ough”
cable. Do not use a null modem cable (usually female-to-female).

You can connec t on ly on e FP-1000 ne twork m odule f or each RS-2 32
port in your host computer. You can add more FieldPoint banks without
using more RS-232 p orts of your host co mp uter, by co nnec ting o ne or

method is to connect the FP-1001 directly to your host computer, if your
host computer provid es an RS- 485 interf ace (c ontac t N atio nal
