Chapter

FP-1000 and FP-1001

Network Module Overview

This chapter provides an overview of the FieldPoint network modules.

The FP-1000 FieldPoint network module connects an industrial RS-232

network to FieldPoint I/O modules. The FP-1001 FieldPoint network

module connects an industrial RS-485 network to FieldPoint I/O

modules.

The FP-1000 and FP-1001 support standard commands (subset 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-1001 use the Optomux protocol. Therefore, after

you have configured the FieldPoint bank (network module and I/O

modules), you can use any application software that supports Optomux

to communicate with FieldPoint modules in the bank.

In a distributed application, many FieldPoint banks are networked

together. You can network up to 25 FieldPoint banks to each

RS-232/RS-485 port of your host computer. Each bank can contain up

to nine I/O modules, thus connecting up to 225 I/O modules per RS-232

(or RS-485) port in your host computer. You can further increase your

field I/O count by using more RS-232/RS-485 ports in your host

computer.

FP-1000 Connects to RS-232

The FP-1000 connects directly to the RS-232 port that is available on

most host computers. Since RS-232 is a point-to-point 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.

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 network module connects directly to an

RS-485 adapter card that is installed in your host computer. Since

RS-485 is inherently a multidrop network, the FP-1001 does 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.

Chapter

Installation and

Configuration

This chapter describes how to install and configure your FieldPoint

network module, connect it to an RS-232 or RS-485 network, and

connect power to the network module.

Installing the Network Module

The FieldPoint network modules have rugged, simple clips for

mounting reliably onto a standard 35 mm DIN rail. Follow these steps

to mount the network module onto a DIN rail. Terminal bases 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.

Rail Clip Unlocked

Rail Clip Locked

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 and opening it to the unlocked

position as shown in Figure 2-1. Then disconnect the terminal base

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.

3. Attach the terminal base to the network module by firmly mating

the local bus connectors.

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

local bus connectors together.

5. Place the protective cover that you removed from the network

module on the last terminal base on the bank, as shown in

Connecting the FP-1000 to the Network

This section describes the network configurations possible with the

FP-1000 FieldPoint network module. The connector pinouts are

described in the RS-232 Interface Specifications and RS-485 Interface

Specifications sections later in this chapter.

Connect the RS-232 port of the FP-1000 to your host computer’s

RS-232 port. Use a 9-pin Dsub male-to-female “straight-through”

cable. Do not use a null modem cable (usually female-to-female).

You can connect only one FP-1000 network module for each RS-232

port in your host computer. You can add more FieldPoint banks without

using more RS-232 ports of your host computer, by connecting one or

more (up to 24) FP-1001 network modules to the RS-485 repeater port

of the FP-1000. This network configuration is shown in Figure 2-5.

This section describes the network configurations possible with the

FP-1001 FieldPoint network module. The connector pinouts are

described in the RS-485 Interface Specifications section later in this

chapter.

One option for connecting the FP-1001 is to connect it to the RS-485

repeater port of an FP-1000 as shown in Figure 2-5. An alternative

method is to connect the FP-1001 directly to your host computer, if your

host computer provides an RS-485 interface (contact National

Instruments for information about available RS-485 hardware). You

can connect up to 25 FP-1001 network modules to each RS-485 port on

the host computer. This network configuration is shown in Figure 2-6.

The multidrop topology used in the networking configurations provides

protection against power failures at individual FieldPoint banks. It

eliminates the possibility that a power failure at one FP-1001 bank

might affect the communication between other banks in your network.

Because the FP-1000 provides an RS-485 repeater, a power failure at

that bank will affect communications.

Connecting to the Serial Ports

The following sections give information about the RS-232 and RS-485

ports on the network modules, and how to connect to them.

The RS-232 port on the FP-1000 network module is a full-duplex

interface. The RS-485 port on the FP-1000 and FP-1001 network

modules are optically isolated, full-duplex interfaces.

Caution: The RS-485 interface on both the FP-1000 and the FP-1001 modules is

isolated from the rest of the FieldPoint system, including the power supply,

backplane, and the RS-232 interface on the FP-1000. It is isolated with a

galvanic and optical isolation barrier, which has been designed and tested

to withstand fault voltages of up to 2500 Vrms. However, the safety rating

of this barrier is only for working voltages of up to 250 Vrms. Do not use

the isolation barrier of the RS-485 interface as a way to protect human

contact from common mode voltages of more than 250 Vrms. Also note that

while the RS-232 interface on the FP-1000 is isolated from the RS-485

interface, it is NOT isolated from the power supply inputs (the V and C

terminals).

2-5

FieldPoint FP-1000/FP-1001 User Manual

Chapter 2

Installation and Configuration

Both serial interfaces are self-configured to use the following

parameters:

1 Start Bit, 8 Data Bits, 1 Stop Bit, No Parity

The supported baud rates are 300, 1200, 2400, 9600, 19200, 38400,

57600, and 115200. Refer to the Configuring the Network Module

section for information about setting the baud rate for your modules.

Host computer RS-232 ports and RS-485 interface boards provide FIFO

buffers for transmit and receive that help to decrease the overhead on

host computers. National Instruments recommends that you enable

these FIFO buffers in your host computer or RS-485 interface board for

best performance.

RS-232 Interface Specifications

RS-232 specifies a maximum cabling distance of 50 ft, but

improvements in line drivers and cabling technology often allow you to

design your network beyond the recommendations of the specification.

The RS-232 connector is 9-pin female Dsub connector whose pinout is

shown in Figure 2-7.

Legend:

NC = Not Connected

GND = Ground

RX = Recieve

TX = Transmit

RTS = Request to Send

DSR = Data Set Ready

Figure 2-7. RS-232 Connector Pinout for the FP-1000

FieldPoint FP-1000/FP-1001 User Manual

2-6

Chapter 2

Installation and Configuration

The FP-1000 does not use RS-232 hardware handshaking, but it still

asserts the RTS and DSR signals for host computers or software that

may require these signals. A host computer that does not use these

signals does not need to connect to them.

RS-485 Interface Specifications

RS-485 specifies a maximum cabling distance of 4000 ft, but

improvements in line drivers and cabling technology often allow you to

design your network beyond the recommendations of the specification.

If even longer distances are desirable, you can use RS-485 repeaters.

An RS-485 stub is created when you tap the RS-485 backbone to form

a T-junction. RS-485 stubs must be less than 3 in. long. However, you

can create longer stubs by using an RS-485 repeater to start the stub,

ensuring that the repeater is close to the junction.

The RS-485 connector is a 5-pin Combicon connector whose pinout is

shown in Figure 2-8.

Figure 2-8. RS-485 Connector Pinout for the FP-1000 and FP-1001

RS-485 Network Termination and Biasing

An RS-485 network must be terminated at each end of the network, but

not anywhere else. At each end bank, termination resistors should be

installed between the RX pair and between the TX pair. These network

terminating resistors are nominally 120 Ω and are provided in your kit.

To install them, twist the resistor leads with the RS-485 signal wires and

then insert them into the RS-485 Combicon adapter as shown in

Figure 2-9. The 120 Ω resistor in the figure is a terminating resistor.

Figure 2-9. Terminating RS-485 Using the Combicon Adapter

An RS-485 network also needs biasing resistors to protect the devices

on the network against noise during intervals when no RS-485 drivers

are transmitting on the network. The host computer’s RS-485 interface

normally has provision for such biasing resistors. When you are using

FP-1001 network modules directly connected to a host computer’s

RS-485 interface, you should use the biasing feature of the host

computer’s RS-485 interface for better reliability and noise immunity.

The RS-485 repeater interface on the FP-1000 already has biasing

resistors, so you do not need to do anything when connecting one or

more FP-1001 modules to the FP-1000.

Figures 2-10 and 2-11 show typical RS-232 and RS-485 signal

connections and termination for a FieldPoint network. Figure 2-10 is a

Chapter 2

Installation and Configuration

Follow these steps to set the address and baud rate for your network

module.

1. Choose and set a network address. Refer to the following section,

Setting the Network Address, for more information.

2. Choose and set the baud rate. For more information, refer to the

section, Setting the Baud Rate, later in this chapter.

3. Write your address and baud rate settings in the space provided on

the network module label.

4. Apply (or cycle) power to the bank, to enable the network module

for the new network address and baud rate.

5. Make the same address and baud rate changes in your FieldPoint

software. Refer to the FieldPoint software online help for more

information.

Setting the Network Address

Switches 1-5 set the network module address. The addresses of the

terminal bases in a FieldPoint bank are automatically configured by the

network module to be sequentially higher than the network module’s

address. For example, if the network module is set to address 20, the I/O

module in the terminal base adjacent to the network module is at

address 21, the next I/O module is at address 22, and so on. A terminal

base is assigned an address whether an I/O module is inserted on it or

not.

Note:

If you are connecting more than one network module to the same host

computer port, ensure that each network module has a unique address.

Connecting Power to the FP-1000 or FP-1001

An 11-30 VDC power supply is required by each FieldPoint network

module. The network module filters and regulates this supplied power

and provides power for all the I/O modules in the bank. Therefore you

need not provide power separately to each FieldPoint I/O module in the

bank.

The power connector is a 4-pin screw terminal connector whose pinout

is shown in Figure 2-13.

Figure 2-13. FP-1000 and FP-1001 Power Connector Pinout

The two terminals labeled V are internally connected on the network

module, as are the two terminals labeled C. Power must be applied to

one V and C pair for operation of the FieldPoint bank. If you want to

power your field I/O devices from the same power supply, the second

V and C pair provides a convenient means of connecting power to the

V and C terminals of a terminal base. Figure 2-13 shows this optional

connection.

If your field I/O devices need to be powered separately, you can use the

terminals provided on each terminal base for such power supply

connections. Refer to the documentation that came with your terminal

base and I/O module for more information on powering your field I/O

devices.

Calculating Power for a FieldPoint Bank

The power requirements for a FieldPoint bank that uses an FP-1000 or

FP-1001 network module are calculated as follows:

Power = 1 watt + 1.15 * ∑(I/O Module Consumption)

The operating instructions for each FieldPoint I/O module contain

power consumption information.

Chapter

Feature Set Description

This chapter describes the feature set for the FP-1000 and FP-1001

network modules.

Both the FP-1000 and FP-1001 have an identical feature set, so this

chapter uses the term network module to refer to either one. Any specific

differences are noted.

High-Speed Local Bus

The network modules provide a high-speed local bus for

communication to the I/O modules in the bank. The high-speed local

bus has low overhead that enables fast response to commands from the

host computer.

Network Watchdog Timer

The network module can detect unexpected periods of network

inactivity and respond to it in a user-defined way. The network

watchdog timer feature enables you to guard your system against

failures in the network connection, cables, or host computer, and to put

the channel outputs in a user-defined state (the watchdog state) if such

failures do occur.

You can set the watchdog output values to be different from the

power-up output values. Some system applications do not differentiate

between power-up output values and watchdog output values, while

other applications treat the two conditions differently. The network

module supports both types of applications.

By default, the watchdog timer for the bank is disabled on power up. To

use the watchdog timer, set up the following parameters. You can use

either the FieldPoint Explorer software or the FieldPoint command set.

•

Watchdog data value for each channel.

Watchdog data enable/disable status for each channel.

3-1

FieldPoint FP-1000/FP-1001 User Manual

Chapter 3

Feature Set Description

•

Watchdog enabled/disabled status for each I/O module.

Watchdog timeout value for the bank.

Note:

Each bank has only one watchdog timeout value that is common for all the

modules in that bank. In addition, the current watchdog timeout value is

not stored when you store the SnapShot.

SnapShot Feature

Many applications require that, upon startup, the system’s I/O power up

with user-specified configuration and output levels rather than factory

default settings. The SnapShot feature provides you with a single-step

method to store the current state of your FieldPoint bank for use as the

power-up state of the bank.

If you subsequently enable the SnapShot feature, you can ensure that

your system will power up with the configuration and output levels that

you specified when storing the SnapShot.

Prior to storing the SnapShot, you should bring all the channels to the

desired power-up settings. You can use either the FieldPoint Server

software or the FieldPoint command set to change the configuration of

the FieldPoint bank, and then store the SnapShot. The SnapShot stores

all the following information in a single step:

•

Attribute and range settings of each channel.

Output values of each channel.

Watchdog data values of each channel. See the Network Watchdog

Timer section in this chapter for more information.

•

Watchdog data enabled (or disabled) status for each channel. See

the Network Watchdog Timer section in this chapter for more

information.

Watchdog enabled (or disabled) status of each module. See the

Network Watchdog Timer section in this chapter for more

information.

After you store the SnapShot information, you can still choose whether

the network module uses that stored information during future

power-ups. Enable the SnapShot feature if you want the FieldPoint bank

to power-up with the stored SnapShot information.

FieldPoint FP-1000/FP-1001 User Manual

3-2

Chapter 3

Feature Set Description

If you have enabled the SnapShot feature, the network module restores

the stored settings to all I/O modules and channels in the bank every

time you power up, until you disable the SnapShot feature. If the

SnapShot feature is disabled, the FieldPoint bank will power up with

factory-default settings.

At some time you might want to change the stored SnapShot

information. To make incremental changes in the stored SnapShot

information, you can use the features described in the next section,

Programmable Power-Up State.

Note:

The current watchdog timeout value for the FieldPoint bank is not saved

when you store the SnapShot.

The SnapShot feature inherently requires that the entire FieldPoint bank

be at your desired power-up state, since when you store the SnapShot

information, the current settings of the entire bank are stored for use at

future power-ups.

Programmable Power-Up State

The SnapShot feature described in the SnapShot section provides you

with a single-step method to store the current state of the FieldPoint

bank for use as the power-up state. The FieldPoint network module

provides an alternative method to define power-up states that allows

you to store the SnapShot information with more flexibility, as

described in this section.

The Programmable Power-Up State feature enables you to define the

power-up configuration on a module-by-module basis. In addition, you

do not need to actually set any of the channels to the desired power-up

state. You can therefore define the power-up states regardless of the

current settings of any channel of a module.

Optionally, you can utilize the Programmable Power-Up State feature

to incrementally modify previously stored SnapShot information.

If you subsequently enable the SnapShot feature, you can ensure that

your system will power up with the configuration and output levels that

you specified when storing the Programmable Power-Up States.

You can utilize the Programmable Power-Up State feature to

individually store the following information. You can use either the

FieldPoint Explorer software or the FieldPoint command set.

If you have enabled the SnapShot feature, the network module restores

your desired settings to all I/O modules and channels in the bank every

time you power up, until you disable the SnapShot feature.

HotPnP (Hot Plug and Play)

The HotPnP feature simplifies system installation, configuration, and

maintenance. With the HotPnP feature, you can remove or insert I/O

modules into the FieldPoint terminal bases while power is on, even if

the system is already engaged in network activity. You do not need to

power down the entire system or even a bank to insert, remove, or

replace I/O modules. In addition, you do not need to change the

operation of the host computer or software to use the HotPnP feature.

When you insert an I/O module with the power on, it is automatically

recognized, configured, and made available on the network. The

following sections describe how the HotPnP feature works under

different conditions.

Note:

An I/O module can be hot-inserted only if an empty terminal base is already

available in the bank. You should not add or remove terminal bases while

power is applied to the bank.

FieldPoint FP-1000/FP-1001 User Manual

3-4

Chapter 3

Feature Set Description

HotPnP During Power-Up

Upon power-up, the network module automatically uploads an

electronic data sheet (EDS) from each I/O module in its bank. The

network module then configures each I/O module in the bank to factory

default settings in the module’s EDS, or stored SnapShot settings if the

SnapShot feature is enabled.

HotPnP During Operation

You may need to insert or replace one or more I/O modules in a bank

while your system is operational (power is on and the network may or

may not be active).

Inserting New I/O Modules

When a new I/O module is inserted, the network module automatically

uploads the EDS and configures the I/O module to factory default

settings in the module’s EDS, or to stored SnapShot settings if the

SnapShot feature is enabled. This configuration is accomplished

without any intervention from the host computer or software.

While one or more new I/O modules in a bank are being serviced by the

HotPnP feature, the other I/O modules in the bank remain fully

operational and accessible on the network without any interruptions. As

soon as the network module configures the new I/O module via the

HotPnP service, that I/O module becomes automatically accessible on

the network.

Replacing I/O Modules

When an I/O module is removed, the network module does not

undertake any special course of action for the bank. The host computer

(or the software executing on it) may be unaware that the I/O module is

missing, and may continue to send commands to the missing I/O

module. Each command returns an error response, but the network

module remembers the commands sent to the missing I/O module.

When a new I/O module is connected in place of the one that was

removed, the network module first verifies that the replacement I/O

module is compatible with the one that was removed. If the I/O module

is the same as, or is compatible with, the one removed, the network

module configures the replacement I/O module with its predecessor’s

configuration and output value settings. It also applies the effects of any

commands sent by the host computer while the I/O module was missing.

3-5

FieldPoint FP-1000/FP-1001 User Manual

Chapter 3

Feature Set Description

If the replacement module is incompatible with the one that was

removed, the network module looks at the information stored in the

SnapShot. If the SnapShot is enabled and the replacement module is

compatible with the information in the SnapShot, the network module

configures the replacement module with the SnapShot configuration.

Otherwise, the network module configures the replacement module to

factory default settings.

Feature Set Description

Power-On Self Test (POST)

The power-on self test (POST) is a test suite that the network module

performs at power up to verify its own operational status. The test is

non-invasive and therefore does not affect the operation of the network,

nor does it affect any of your field wiring connected to the terminal

bases in the bank.

If the self-test suite fails, the network module does not participate in the

network communication traffic, thereby eliminating potential conflicts

with the other banks in your network.

The network module indicates POST failure via the STATUS LED.

Refer to the next section, LED Indicators, for more information.

LED Indicators

The network module has four LED indicators: POWER, NETWORK,

ACCESS, and STATUS. Figures 3-1 shows the LEDs on the network

modules.

network increases.

The yellow ACCESS LED flashes when the network module or any of

the I/O modules in its bank respond to the host computer. This LED

indicates that a module in the bank was addressed by a correctly

formatted command, and that the module is responding to that

command (either with a success or error response).

The red STATUS LED is lit when the network module detects a failure.

If STATUS is not lit, the network module has not detected a failure. The

Using the FieldPoint

Software

This chapter describes how to use the FieldPoint hardware with various

servers and software packages.

FieldPoint Software Overview

Your FieldPoint software consists of three parts: the FieldPoint

Explorer, the FieldPoint Server, and a FieldPoint driver for Lookout.

The FieldPoint Explorer and the FieldPoint Server are both 32-bit

applications that run on Windows 95 or Windows NT.

•

The FieldPoint Explorer is a configuration utility for FieldPoint

modules. The FieldPoint Explorer configures the FieldPoint

hardware; the FieldPoint server, which is used with BridgeVIEW,

LabVIEW, LabWindows^®/CVI, and OPC (OLE for Process

Control) client software; and the FieldPoint driver for the Lookout

software package.

The FieldPoint Server manages the communications between the

host computer and the FieldPoint hardware. The FieldPoint Server

is an interface to the BridgeVIEW, LabVIEW, and

LabWindows/CVI software packages from National Instruments.

In addition, it provides an OPC interface for other software

packages that have OPC client capability.

The FieldPoint driver for Lookout manages the communications

between a host computer running Lookout and the FieldPoint

hardware.

You can also choose to communicate with the FieldPoint system using

an Optomux compatible server, or by using the FieldPoint command

set. If you use either of these methods, refer the FieldPoint FP-1000 and

FP-1001 Programmer Reference Manual. You may, however, still use

the FieldPoint Explorer to configure the FieldPoint devices before

running your software.

Using the FieldPoint Software

Using the FieldPoint Explorer

You can use the FieldPoint Explorer to accomplish the following tasks:

•

Configure the characteristics and hardware of a FieldPoint device

network

Configure the tag name space and I/O items of the FieldPoint

Server

Write and read I/O values to and from the FieldPoint hardware

After configuring the FieldPoint system with FieldPoint Explorer, you

can save the configuration in an Industrial Automation Kernel (IAK)

file (.iakfile). This file contains the configuration information

necessary for the FieldPoint Server.

The FieldPoint Explorer includes online help. To get started, run the

FieldPoint Explorer program and select FieldPoint from the Help menu.

Using the FieldPoint Server with BridgeVIEW

To use the FieldPoint Server with BridgeVIEW, you must export the

configuration information saved by the FieldPoint Explorer in an .iak

file to the BridgeVIEW server configuration data store, the Common

Configuration Database (CCDB). After you have configured and tested

your FieldPoint network from FieldPoint Explorer, select Export to

Active CCDB from the File menu option to export the current IAK

configuration to BridgeVIEW.

Once the IAK configuration information is exported to BridgeVIEW,

you can automatically generate BridgeVIEW tags from your FieldPoint

items by launching the BridgeVIEW Tag Configuration Editor and

clicking on the Tag Wizard button.

Refer to the BridgeVIEW user manual for more information about

BridgeVIEW server configuration, the tag configuration editor, the tag

wizard, and the active CCDB files.

Note:

If you edit, rename, or move your .iak configuration file after you export

it to the BridgeVIEW active CCDB, you must export the .iak

configuration file again. Also, if you select another CCDB file as the active

CCDB, you must export the .iak configuration file again, to the newly

selected active CCDB file.

Using the FieldPoint Software

Using the FieldPoint Server with LabVIEW

To use the FieldPoint server from LabVIEW, first configure and test

your FieldPoint device network from FieldPoint Explorer. After you are

satisfied with the configuration, save your .iak configuration file. You

can then access named FieldPoint item values using the LabVIEW

FieldPoint Server Interface.

The LabVIEW FieldPoint Server Interface consists of seven VIs that

are used as an interface to the FieldPoint Server, as well as example VIs

that demonstrate the use of this interface.

•

The FP Open.vi and the FP Close.vi are used to open and close a

communications session to the FieldPoint server, using the

configuration information stored in an IAK file.

•

The FP Create Tag.vi is used to establish a communications session

with an I/O point defined in the IAK file.

After establishing this session, use the FP Read.vi, FP Write.vi, or

FP Advise.vi to communicate with the device.

The FP Get Configuration Info.vi is used to read the names of

communication resources, devices, and I/O items defined in the

IAK file.

During the FieldPoint Server installation, these VIs are installed and

made available in the LabVIEW function palette. For more information

on how to use these functions or the example VIs, refer to the file

Fplvreadme.wri that is installed with the FieldPoint Server, or refer

to the FieldPoint Server online help.

Using the FieldPoint Server with LabWindows/CVI

The LabWindows/CVI interface to the FieldPoint Server is an

instrument driver that has C functions similar to the VIs in the

LabVIEW FieldPoint Server interface. This instrument driver is

installed with the FieldPoint Server if LabWindows/CVI was already

installed on the computer.

After opening a session to the FieldPoint network using the

configuration information in an IAK file, you may either read or write

data using blocking calls or using callbacks. The function panels for

each of these C routines includes information on how to use the

functions.

Using the FieldPoint Software

Using the FieldPoint Lookout Driver

The FieldPoint Lookout driver uses the configuration information in the

IAK file created by the FieldPoint Explorer for its own configuration.

The tag names used with the FieldPoint Lookout driver are the same as

the names assigned using FieldPoint Explorer. There is a separate disk

in your kit that contains the FieldPoint Lookout driver. This disk also

contains documentation for this driver in the lkreadme.wrifile.

Using FieldPoint with Optomux Servers

The protocol used by FieldPoint is compatible with the Optomux

protocol, and you may use Optomux servers to communicate with the

FieldPoint system. However, Optomux servers do not include

provisions for setting all the configurable parameters of a FieldPoint

system (such as input ranges and power up settings). Thus, you should

use FieldPoint Explorer to set up (and optionally store using SnapShot)

the configuration of the FieldPoint hardware before using an Optomux

server.

Refer to the FieldPoint FP-1000 and FP-1001 Programmer Reference

Manual for a description of which Optomux commands are supported,

and how to scale the data returned when using this protocol.
