Emerson Introduces Upgraded CPUs for Bristol Network RTUs

Upgrade CPUs provide a migration path from the installed base of Emerson Process Management’s Bristol Network 3000 RTUs to the company's Bristol ControlWave remote automation system. The migration is made by replacing installed Network 3000 CPU's with the new upgrade CW_35 and CW_31CPUs.

Introduced in 1990, Bristol Network 3000 featured the 3335 RTU and 3331 I/O expansion rack that have retained their status as the RTU of choice by many. However, with Bristol ControlWave, the latest generation 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 system for SCADA applications.

The new CW_35 and CW_31CPU products are intended to offer a cost-effective upgrade path to the Bristol ControlWave architecture, allowing existing Network 3000 customers to maintain their investment in I/O, wiring, communication infrastructure and application program development. The new CPUs are direct replacements for the CPUs in the 3335 RTU and 3331 I/O rack.
