Low Power High Performance Process
Automation Controller
Bristol® ControlWave® LP, from Emerson Process
Management, is a low power high performance pro-
cess automation controller that performs complex
control strategies, collects, time stamps, and stores
data, and communicates in local, remote, and wide
area networks. ControlWave LP offers the features
of an RTU and an automation controller with DCS
functionality.
Designed for control and data acquisition ap-
plications, the ControlWave LP is easily installed
in"remote areas and offers one of the industries
widest operating temperature ranges. Additionally,
due to its small form factor and rugged industrial
design, ControlWave LP offers an outstanding ability
to match the requirements of the most demanding
process plant and remote SCADA system environ-
ments. Above all, Emerson has developed this inno-
vative controller to provide cost-effective solutions
by minimizing the time required for installation and
conguration.
The ControlWave LP complements the ControlWave
and Network 3000 family of process automation
controllers and RTU’s. The ControlWave LP is
compact in size and offers the full programmabil-
ity of ControlWave Designer IEC 61131 compliant
software, and communicates via standard BSAP, as
well as other industry standard protocols.
The ControlWave LP is available in an open chassis
assembly for mounting to a panel or within an enclo-
sure. The unit is a three-board assembly consisting
of a CPU board, a Multifunction Input/Output board,
and a Power Supply/Sequencer board. All eld

OpenBSI
Simply Creative
OpenBSI (Open Bristol System Interface) is a set
of network setup, communication diagnostic, and
data viewing utilities that provide access to both
ControlWave and Network 3000 controllers and
RTUs. OpenBSI is the only product available in the
industry to bring such unique functionality and ease
of use to the network level. At the core is the com-
munication interface, written as a Windows 98/NT &
2000 communication server API through which other
client applications communicate with the Bristol net-
works. OpenBSI supports both serial BSAP protocol
and Ethernet Internet Protocol communication to
ControlWave and Network 3000 RTUs and control-
lers. Above this communication layer are a group
of applications known as OpenBSI Utilities. These
client utilities communicate through the server to
collect and manage data gathered from the network,
generate les based on collected historical data,
collect alarms, and monitor and control OpenBSI
communications.
OpenBSI Utilities
OpenBSI Utilities provide a full set of communica-
tion and data access capabilities for operators
directly connected to the ControlWave network as
well as remote operators connected through one
of the main operator PCs. The OpenBSI includes
utilities to easily create the OPC server database
from the ControlWave application conguration les,
then provide access to those variables to any OPC
compliant HMI product for operator display and
interaction with the ControlWave network. HistTools

NetView is the basic conguration and application
interface for all network operations. NetView uses
a tree structure for network graphical display in the
Windows Explorer style. Network nodes can be
added on-line by simply dragging the node Icon into
the tree. This invokes a conguration Wizard simpli-
fying network setup. Through the NetView Wizard,
the necessary network parameters are entered for
node and IP address, alarm and message routing,
and network communication media. Once cong-
ured, selecting any node allows direct access to the
common OpenBSI utilities to reprogram, download a
new application to the node, review communication
statistics, view real-time data through DataViewer,
and edit controller/RTU properties.

Network 3000 nodes used to collect and display
several types of process data, including signal
values, data array values, signal lists, and audit
trail information. Operators have the ability to alter
signal values. Multiple DataView windows may be
open simultaneously.
TechTools – OPC Server & ActiveX
Controls
The Technicians Toolkits consist of a set of congu-
ration wizards and standard web pages which are
used to congure a newly installed ControlWave or
modify those parameters on an existing controller.
The key components of the Technicians Toolkit are:
WebBSI- A set of Active X controls allowing commu-
nication access to ControlWave are provided for en-
gineers to develop their own custom web pages us-
ing any standard package such as Microsoft® Front-
Page. Active X controls allow data to be viewed in
any compliant container (such as Microsoft Excel
and Word or Visual Basic), or a compliant web page
Browser such as Microsoft Internet Explorer.
Real-time ActiveX Controls
One of the many benets TechTools brings to
you is our use of open standards such as ActiveX
Controls. AcitveX is another of the Microsoft stan-
dards, which allow plug and play with any ActiveX
container, using Microsoft ActiveX container tech-
nology such as Visual Basic, HTML web pages, and
Microsoft Excel
The set of available ActiveX Controls provides the
basic functions necessary to communicate and col-
lect data from ControlWave.

High Historical Data Integrity
The ControlWave Historical Data Collection sys-
tem provides time-stamped historical data storage
in ControlWave nonvolatile Flash memory. The
historical data is collected, through OpenBSI, on a
schedule or demand basis and converted to .CSV
and ODBE compliant le formats for use spread-
•
•
•
sheet and database reports. If data is missed due
to a communication failure, it is collected when the
communication is reestablished and the PC histori-
cal database is backlled with the missing data.
This distributed historical database architecture
proveides the greatest data reliability and integrity
during communication or PC downtime.
Another important historical feature is the Audit
storage and collection system. The audit trail is a
le stored in ControlWave Flash memory containing
signicant events and time-stamped alarms. The
alarms stored in the Audit system provide a histori-
cal archive in addition to the real-time alarm report-
ing system. This le is also collected through Open-
BSI and presented as a text le in the PC. This
Archive Collection – collection and storage to
disk of the ControlWave archive data
Audit Collection - collection and storage to disk
of the ControlWave audit data.
Exports data les to third party, .CSV & ODBC
applications
DDE compliant for use with other popular
Windows applications
OPC Server
With industry demand for open standards,
ControlWave answers the call by embracing tech-
nologies that open the door for maximizing your
efciency and productivity. The OPC standard was
developed by the OPC Foundation comprised of
hardware and software suppliers from the process
control community. OPC allows the engineer to
select best in class hardware and software with con-
dence in their interoperability. Our OpenBSI OPC
Server was among the rst to comply with the OPC
Foundation alarm and event server specication.

Communication Protocols
Like all Emerson products, ControlWave supports
BSAP (Bristol Standard Asynchronous Protocol),
Modbus, DF1 and serial ASCII as standard func-
tions. These protocols are implemented in ash-
ware so no additional hardware is required to use
any one or a combination of all protocols.
All of Emerson’s Bristol Network 3000 and
ControlWave RTU and controller products support
BSAP protocol. BSAP is widely accepted as provid-
ing exceptional data integrity and greatly simpli-
es communication between controllers. BSAP is
provided with interfaces for Master/Slave, vertical
networks and Client/Server, horizontal networks. In
either case, variable lists are created in each con-
troller that are easily passed from server to client or
slave to master.
BSAP meets the denition of an industry-standard,
open-architecture protocol because if conforms to
ISO standards 2629, 1745 and 2111, it is not propri-
etary in that Emerson does not charge a license fee
and makes the protocol and documentation avail-
able to anyone.
While BSAP is an open protocol, the added func-
tionality of the messages passed provide much
more capability than is found other networks.

Modbus - Modbus is often considered a de-facto
standard protocol because broad usage as ei-
ther the primary or a secondary offering in many
measurement and control related products. Even
with its common use, Modbus protocol actually
has many variations. Consider Modbus RTU and
Modbus ASCII, Master &

Slave, Serial and TCP/IP Open Modbus. In addi-
tion there are consideration regarding supported
function codes, oating point values and byte order.
Emerson’s Bristol products supports the following:
Modbus serial and TCP/IP Open Modbus
(Ethernet)
Master and Slave
Modbus RTU and ASCII
Modes 1 - 7, 8, 15 & 16
IP modes 51, 52 & 53
Integer and IEEE 4 byte oating point
Allen Bradley DF-1
DF-1 protocol is the primary mechanism to inter-
face to Allen Bradley PLCs and interface devices.
ControlWave and Network 3000 both support DF-1
half-duplex master protocol.
Generic Serial Protocol
The Generic Serial Protocol is a Master and Slave
protocol used to send and receive messages typi-
cally with third party serial ASCII devices. This
protocol can be used to interface with such devices
and message boards, card readers and many mea-
surement devices.
Multi-User Security Access
Security is an essential element of any open
system, particularly those with Internet access.
ControlWave employs a User Name/Password ac-
cess system protected by a 56-bit encryption tech-
nique through the TCP connection. There can be up
to thirty-two users, who sign-in using their name and
password. Both the name and the password can be
up to sixteen characters.

The security system provides for up to sixty-four
access rights to read and write data values and les
via FTP, access and congure historical and audit
data information, edit conguration, run internal
diagnostics, read and reset system status. It further
allows the programming software to read, write and
download the ControlWave.
The Secure Data Advantage
ControlWave sets a new standard for providing in-
telligent control at the point where control is needed.
Whether you need control on the plant oor or at a
remote site in the “middle of nowhere” ControlWave
is the solution for control, communication and
secure data to help you make the right operating
decisions.
ControlWave was designed to provide the optimum
level of data security using a distributed database
architecture. All data including time & date stamped
alarms, alarm limits, and historical data are stored
locally in each industrially rugged ControlWave,
thereby distributing your data integrity risk. To
further ensure that the data is always current and
historically accurate, the historical data is stored
in non-volatile ash memory within ControlWave.
Historical data is even maintained during and after
program downloading.
When historical data is collected from ControlWave,
it is converted and appended to .CSV and/or ODBC
compliant databases but does not destroy the origi-
nal historical data stored in ControlWave. Thus, a
exible and secure historical data system is clearly
recognized as a benet to virtually every industrial
application.
The Bridge Between Systems
Continuing our tradition of introducing innovative
new solutions while maintaining compatibility with
existing systems, Emerson again provides a migra-
tion path for existing customers by bridging the new
ControlWave system with Network 3000 systems
already in place. The network bridge is enabled
by employing the open architecture technologies
afforded by TCP/IP and OPC in both networks.
TCP/IP allows seamless Ethernet connectivity to
both networks as well as the corporate Intranet so
both ControlWave and Network 3000 controllers
can reside and communicate on the same LAN.
Emerson’s Bristol OpenBSI OPC Server facilitates
the merging of the two networks for technical, engi-
neering and operator data access. The data source,
conguration and path are completely transparent to
the OPC client. Real-time data can also be passed
between the two communication networks making
this a total Plant Automation Management Solution.
