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 benets 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.
Benets
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 exible 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 exibility
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
