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

Features

•150 MHz, ARM CPU

•Real-time clock

•Conforms to DPC3330, 3335 and RTU3310 chassis design

•Supports most existing 33XX I/O cards

•ControlWave Designer IEC 61131-3 programming
