SECTION 1
1-1 THE NGA 2000 CONCEPT - INTRODUCTION
NGA 2000 stands for "Next Generation Analyzer". It describes a new concept in gas Analyzer design. The basis for this concept is the
division of the traditional Analyzer functions into
modular parts, connected by a digital communication link called LON.
Traditional Analyzers contain the "physics" - the
mechanism for detecting the gas in question and a means of controlling the operation of and
getting data from the physics. This normally
consists of a display with associated controls on
the front of the box, and "I/O" (input/output)
consisting of an analog or sometimes RS232
output, together with some relay contacts, on
the back. Power is supplied by an AC connection to the wall plug. Each Analyzer in a system
has to contain all of these components.
In the NGA 2000 concept, the physics is separated from everything else into an "Analyzer
module", and a single "Control module" or
"Platform" (so called) contains the control, display, I/O and power supply components.
Communication between the Analyzer module
and the Control module is by means of a sophisticated digital communication system made
by the Echelon Corporation, called LONWORKS™ or LON™. There are many subtleties involved in such systems, but the NGA
2000 and the LON hide almost all of these from
the user. A great deal of the sophistication of
the NGA 2000 concept is involved in making the
communication system extremely simple to use
and in removing the complexity that, for example, your MIS administrator has to deal with
while managing the LAN (Local Area Network)
you probably have to use at work!
A typical NGA 2000 system then consists of a
number of different types of Analyzer modules
connected to a single Platform, with some selection of I/O provided according to the particular needs of the user. Control of the entire
system takes place through the single Platform,
and any I/O to the system goes through it. (It is
also possible for a computer to talk directly to
the Analyzer modules without the need of a
Platform, but that is outside the scope of this
document.)
1-2 THE DIGITAL COMMUNICATIONS SYSTEM –
INTRODUCTION
The NGA 2000 uses a proprietary digital communication system made by Echelon Corporation, called LONWORKS™ or LON™ for short.
It is a sophisticated system that deals with most
of the subtleties required without user intervention or knowledge, but there are certain aspects
of it of which you should be aware.
The LON sends data in packets called "Variables". These are named, so that, for example,
the main output of an Analyzer is contained in a
variable called "PVA". Its range is contained in
a variable called "CRANGE". These variables
are emitted by the source and read by other
modules on the network that are interested in
them.
I/O Modules contain input variables of the same
name, and when the I/O is "bound" to an Analyzer module, the contents of the Analyzer's
PVA are automatically communicated to the
I/O's PVA, so that it now knows what the Analyzer's reading is. It can convert it to a 4-20mA
signal, or whatever it is configured to do. Obviously it is important that the I/O Module knows
which Analyzer to listen to!
The way we tell the I/O Module which Analyzer
it should pay attention to is to "bind" it to that
Analyzer. This process selects an Analyzer,
selects an I/O Module, and ties them together
so that the set of Analyzer variables is bound to
the equivalent set of I/O variables, and the two
act as if they are one unit. The process itself is
described below, and it is much easier in V2.3
than in V2.2 and earlier versions. It is the only
thing you have to do to configure the LON.

Model NGA 2000 Platform
The other thing to realize is that the LON is extremely reliable. Any apparent problem with it
has always been proved to be from some obvious error, like a broken wire. It is possible to
overload it, and there is information in this and
the reference manual about this, but once a
system has been setup the LON itself keeps
working. If there is a problem, look for other
things besides the LON to be at fault!
1-3 PLATFORM OVERVIEW
This manual describes the Control and I/O capabilities of the Platform part of an NGA 2000
system.
NGA 2000 system consists of three basic elements:
• Platform components
• Analyzer modules
• Input/Output (I/O) Modules
The Platform serves as a local operator interface for up to six (ten for V2.3 and higher) Analyzer modules. It consists of a group of
components that can be assembled in many
different configurations depending on the user's
needs. It can be composed of any workable
collection of the following:
• Operator Interface - Front Panel,
Display and Keypad
• Power Input Module/ Power Supply
Board
• Platform Controller Computer
• One or more of a number of I/O
Modules
• Enclosure.
The NGA 2000 family of gas Analyzer modules
utilizes proven methodologies such as:
• Non-dispersive infrared (NDIR) to
measure gases such as carbon
monoxide (CO), carbon dioxide
) and sulfur dioxide (SO2)
(CO
2
• Paramagnetic (PMD) for meas-
urement of oxygen
• Chemiluminescence (CLD) for
measurement of nitrogen oxides
(NO and NO
• Flame ionization detection (FID) for
measurement of total hydrocarbons (THC).
• Further modules made in Europe
and described in their own manuals. These include the MLT (a
multi-analysis module) and the
NGA 2000 II series.
These gas detectors are packaged in standard
sized modules that can be linked together via
the LON communications network. The modularity of NGA 2000 allows for the use of multiple
interchangeable Analyzer modules with no
change in overall operational characteristics.
The I/O Modules provide signal input and output
capability outside of the NGA 2000 communications network and are designed for easy installation in the Platform. I/O Module options
provide analog and digital signals, dry contact
closures for alarms and calibration valve sequencing, and accept remote signals for range
change and calibration initiation. These I/O
Modules contain a small computer that operates
autonomously providing I/O capability through
the LON connection without burdening the
Analyzer module computers.
)
X
The Platform is also available in a dual version,
with two complete independent sets of electronics in one enclosure. Such dual versions
act as two separate Platforms and allow two independent Analyzer systems to be run from one
place. The front panel in this case consists of
two half panels directly mounted on the chassis
with no hinges.
1-2 Description and Specifications Rosemount Analytical Inc. A Division of Emerson Process Management
The SIO Board and DIO Board are extensions
to the Platform Controller Board. They plug into
the back of the Platform just as do the I/O Module boards, but they do not contain on board
intelligence. The Platform will only accept one
SIO board but it is possible to add up to four
DIO boards - but only if the software in the
Platform is V3.3, or higher. (At the time of writing, this software is not available in the USA.)
Model NGA 2000 Platform
Instruction Manual
760006-A
September 2001
The LON I/O Module boards allow for external
LON connections to the Platform.
Components that comprise the Platform and the
I/O Modules can be assembled in other configurations depending on user needs.
NOTE
The Platform controller board software
must be of a later major revision than
any Analyzer module software. For
example, a V2.2 Platform controller
board will work with V2.2.1 Analyzer
modules, but not with V2.3 Analyzer
modules. The ".1" after the V2.2 refers
to a minor revision, which is compatible with the V2.2 Platform controller
board software.
NOTE
It is strongly recommended that you
note the actual software revisions that
you have. Service or support people
will be able to diagnose any problem
you may have more easily if this information is immediately available.
The revision is marked on each component, as well as noted in their Manufacturing data menus.
1-4 THE LON – THE NGA DIGITAL COMMUNI-
CATIONS NETWORK
The NGA 2000 Digital Communications Network
operates over a bi-directional, peer-to-peer, twowire system at a rate of 78 kbps. Modules are
connected with RJ-45 modular connectors and
UL level 4, 100 Ohm LAN cable. This means
that there is a single wire connection between
all the modules on the network. It plugs into
each module using a plug much like standard
telephones use. (In fact the wiring is not critical,
plain wire connections will work well over reasonably short distances such as 100 feet.)
The network utilizes LONWORKS®, an open
control networking technology developed by the
Echelon Corporation. This uses the
LONTALK™ protocol. The combination of the
NGA 2000 modular architecture with the robust
LONTALK™ protocol allows the capability to
“multi-drop” nodes to create a distributed net-
work. This is to say that it is possible to connect
many devices onto the same network, and the
network protocol keeps everything working
without conflicts.
Every Analyzer modules or I/O Module node
that communicates to the network contains a
NEURON CHIP. This chip integrates three microprocessors, ROM, RAM, and EEPROM
memories, timers, multifunctional I/O, and the
network interface. From the user perspective
the inner complexities of the LON are thoroughly hidden from view and can safely be ignored.
The network is self-installing upon startup. The
Platform acts as a Network Manager, assigning
addresses and generating its own database
automatically. Manual intervention is only
needed to determine linkages (“binding”) between Analyzer modules and I/O Modules. This
means that all you have to do is to connect everything and power it up, and then tell it which I/O
Module is connected to which Analyzer. Once
this has been done once, it never needs to be
done again unless modules are exchanged or
added.
Each NGA 2000 Analyzer module transmits
over two hundred pieces of data (called variables) that are characteristic of its specific gas
detection methodology. In addition to the main
reading - the primary or process variable (gas
concentration), many other parameters and
pieces of diagnostic information are available.
This data includes:
• Manufacturing data such as serial
number and software revision
• Configuration setup for calibration
control, component temperature
and other alarm set points, and
linearization parameters
• Operational status conditions such
as faults and calibration
• Secondary variables such as type
of gas measured, flow, temperature, and pressure readings
• Historical data such as known
good calibration values and factory
configuration settings

1-5 PC INTERFACE
There are several ways of using the NGA 2000
system with a PC. The Platform can support
RS232 or RS485 interfaces, using either AK or
Modbus as the protocol. Modbus is described
in detail in this manual, and AK is touched on
here and more extensively in the NGA 2000
Reference manual.
It is also possible to setup a PC to communicate
directly with the LON. The easiest way is to use
the Rosemount Analytical DDE Server, together
with a set of suitable hardware. This is described briefly in the NGA 2000 Reference
manual, and in detail in the DDE Server manual.

Variable and I/O Modules can still send accurate data to external recording devices. If
the controller loses contact with an Analyzer, it indicates this fact with the phrase
“No Data” replacing the normal Analyzer
reading.
c. Power Input Module/Power Supply
Power can be supplied to all NGA 2000
components through the Power Input Module, which plugs into the Backplane. External line voltage (85 to 264 VAC, 50 to 60
Hz) is supplied to the Power Input Module
and conditioned for usage by other NGA
2000 components. See Figure 1-3 and Figure 1-10.
The Power Supply Board also plugs into the
Backplane and conditions incoming power
for usage by all modules (only one Analyzer
module). The Power Supply Board provides
+24 VDC at 5A.
Alternatively, the user may supply regulated
24 VDC directly to the Platform through the
Power Input Module. If multiple Analyzer
modules are used, a larger 30 A Bulk Power
Supply is required to power the system.
If the user initially applies AC power and
then applies DC power, the DC circuitry assumes control, and all components may
continue operating without interruption but
may reset depending on the current draw. If
the user initially applies DC power, application of AC power will have no effect. DC
power will remain in control. If both AC and
DC power have been applied, removal of
DC power will reset the system, and AC circuitry will then assume control.

1-9 MULTIPLE MODULE COMPONENTS AND
SYSTEM INTEGRATION
The Rosemount Analytical NGA 2000 architecture provides significant system integration capabilities.
The compact 5.25" height and component
modularity allow for space efficient mounting,
thus decreasing the required panel or rack
space required by conventional Analyzers. The
Analyzer modules may be mounted virtually
anywhere inside a panel; they can be rack
mounted, floor mounted, installed inside the
Platform, or even externally located.
Since a single Platform can accommodate up to
ten Analyzer modules and up to five I/O Modules, the total number of "Nodes" allowed in any
one Platform group is fifteen. This combination
of Nodes may consist of any number of Ana-
lyzer modules and I/O Modules which total fifteen or less. Should additional I/O Modules be
required, these may be housed in an ancillary
Analyzer enclosure. Additionally, some Analyzer modules, such as the MCFID (Multi Component Flame Ionization Detector), or MLT
(Multi Method Multi Component) Analyzer modules, actually provide discrete analysis of more
than a single component and thus are considered, by the Platform, to be more than a single
Analyzer. Once a "Node Group" has been configured it may be networked with additional
Node Groups by means of a Router Assembly
(see Figure 1-9) which provides a discrete address for that Node Group and isolates it from
other Node Groups.
Individual Analyzer modules require 24 VDC
power. As shown in Figure 1-8, this power may
be provided by individual power supplies located in the Platform or by the 30 A Bulk Power
Supply which can provide up to 30 amps of 24
VDC power. The 30 A Bulk Power Supply can
provide power for up to 10 NGA 2000 components.
Table 1-1 may be used to calculate the total
number of Analyzer modules and I/O Modules
which may be supported by a single Platform
(Node count ≤ 15), and the total power requirements for any single Node Group (30 A Bulk
Power Supply ≤ 30 Amps).

The Dual Analyzer Enclosure simply provides
space for two Analyzer modules as well as rear
panel power and network connections for both.
The front is a blank panel. Note the following
about the Dual Analyzer Enclosure:
If two Analyzer modules are installed, the network connection between the two Analyzers
must be made
If only one Analyzer module is installed, only
one cable need be connected to the network or
Platform supporting the Analyzer module
If a standard Platform is used in conjunction
with multiple module components, power should
be connected to the Platform's 24 VDC connector on the Power Input Module and the network cable should be connected to the Network
Port (see Figure 1-3).
The Single Analyzer Enclosure provides additional flexibility in system design. It is a standard
Platform (with room for one Analyzer module)
with no front panel display. It can be ordered
with or without a 5 A Power Supply Module, depending on whether the user can provide
24 VDC power.
and multiple Analyzer modules) where the standard integral 5A Power Supply Module housed
inside the Platform is not sufficient. The supplemental 30 A Bulk Power Supply is capable of
powering up to 10 NGA 2000 components, but
is limited to 30 Amps (refer to Table 1-1)
WARNING.
OVERHEATING HAZARD
To prevent the 30 A Bulk Power Supply from
overheating ventilation openings on the top,
bottom and rear of the enclosure should not
be blocked.
NOTE
Early multi-module power supplies
were supplied with 5A fuses installed,
these fuses were inadequate for the
HFID (Heated FID) and WNX (Wet NOx)
Analyzer modules. When powering
these modules, 8A fuses are recommended. The internal wiring is adequate for this current, early
supplemental supplies are, however,
limited to 25 A total.
The 30 A Bulk Power Supply provides the ad-
ditional 24 VDC energy necessary to power an
entire system (standard Platform, I/O Modules,
