Overview

Introduced initially in 1988, the 3330, 3335 and

3310 have retained their status as the RTU of

choice by many loyal customers. However, with the

growing popularity of Bristol® ControlWave®, from

Emerson Process Management, the latest genera-

tion hybrid PLC/RTU products, customers have

expressed interest in an inexpensive migration path

to allow them to realize all of the benefits of the

new ControlWave technology without replacing their

entire SCADA system.

The new CPU products, named CW_10, CW_30,

CW_35 and CW_31 (generically CW_XX), are

intended to offer a cost-effective upgrade path to the

ControlWave architecture for existing 33XX systems

by allowing you to maintain your investment in I/O,

wiring, cabinets and enclosures, communication

infrastructure and application program development.

The CW_XX CPUs are direct replacements for the

33XX CPUs. You can easily remove the existing

CPU and communication cards and replace them

with the new ControlWave architecture cards.

The CW_XX CPUs support all of the commonly

used analog, discrete and counter I/O cards, as

well as modems and radios currently installed in the

RTUs. Communication compatibility is maintained

through the same use of BSAP and Modbus proto-

cols as were used in the 33XX.

Benefits

The ControlWave architecture offers several ad-

vantages over existing 3310/3330/3335s including

increased compatibility with industry standards such

as IEC 61131-3 programming, Ethernet, IP and FTP

communication, support for 56 bit encrypted User

Name/Password security sign-on and multiple user

access levels. It also offers much greater execution

speed, lower power consumption and a larger and

more flexible memory model.

Faster performance allows more demanding

applications
More memory allows larger applications and

data storage
Lower power consumption minimizes solar and

battery requirements
ControlWave Designer offers increased

programming flexibility

Historical data is maintained on application

download for higher data integrity
CW_XX dual Ethernet option allows network

segmentation without expensive external

routers
Enhanced security protection
Buffered communication ports enhance

throughput and allow multiple slave ports
