Emerson Expands Bristol® ControlWave® Remote Automation Technology for Oil & Gas and Water and Wastewater Industries

New standards-based ControlWave ExpressPAC breaks the price/performance barrier for small integrated RTU's

WATERTOWN, CONN (April 20, 2006) - Expanding its recently acquired Bristol® ControlWave® remote automation technology, Emerson Process Management introduces the ControlWave ExpressPAC, a highly integrated pre-engineered package solution that combines the new ControlWave Express RTU with a variety of options commonly required in SCADA applications.

ControlWave is a flexible remote automation system based on worldwide industry standards for programming and communications. ControlWave combines the best technologies provided by PLC, RTU and automation architectures into a Hybrid system well suited to remote applications in the energy, water, and wastewater industries.

Adding significant scalability to the ControlWave family, the pre-engineered ExpressPAC breaks the price/performance barrier for small integrated RTU products, offering proven ControlWave technology in a value-priced, space efficient package required in small I/O point applications such as water pump, tank, well and reservoir control, wastewater lift station and storm water monitoring, and natural gas well, storage and plunger lift control.

ControlWave ExpressPAC includes an Express RTU, a compact Nema 4X rated enclosure, power supply and solar panel options with battery backup, operator display/keypad input options, and wireless communication options. ExpressPAC eliminates the need for in-house panel and packaging design and fabrication resulting in lower initial installation cost. This also standardizes the maintenance effort to reduce the long term cost of ownership.

ControlWave ExpressPAC offers rugged, long-term reliability, wide temperature operation from -40 to +70° C for remote sites, and very low power consumption for solar applications. In addition, the system has been designed to meet CE and U.L. Class I, Div. 2 hazardous location requirements.

Emerson has leveraged Bristol communications and advanced control technology to design ControlWave ExpressPAC for use in large or small RTU applications. The ExpressPAC has three serial communication ports and one optional 10/100 Mb Ethernet I/P port. Bristol ExpressPAC facilitates communication with other devices through widely accepted networks such as TCP/IP open Modbus, serial Modbus, DF1, DNP3 and HART. Bristol BSAP protocol is a standard feature. For open access to most HMI products, Emerson's flexible, easy to implement Bristol OPC Server is offered.

ControlWave ExpressPAC includes the ControlWave Designer programming software that supports all five IEC 61131-3 programming languages. The Designer programming software is enhanced with a powerful library of ACCOL III process control function blocks allowing the use of a single controller for logic, control functions, measurement, calculations and data storage. Engineers can also develop their own reusable function blocks, further reducing engineering time and cost. These capabilities are further enhanced with time stamped alarming and historical archive storage within the PLC/RTU to provide maximum data integrity. This data is automatically recovered following a communication failure.
