| Emerson introduces new Bristol remote terminal unit Emerson Process Management introduces the ControlWave Express, a versatile, compact, low profile remote terminal unit, RTU, with low power consumption for remote installations. Users can use the Express RTU hardware as a component of networked systems for remote applications, or have the option of selecting the RTU as part of the Bristol ExpressPAC, a complete package system for SCADA applications. ControlWave is a flexible remote automation system. The ControlWave architecture combines the best automation technologies and concepts into a hybrid system well suited to meet the remote application requirements of the energy, water, and wastewater industries. ControlWave technologies are being used to reduce project costs and increase operations efficiency in hundreds of remote automation applications globally. ControlWave Express offers rugged, long-term reliability, wide temperature operation from -40 to +70° C for remote installations and very low power consumption for solar applications. As for communication ports, the Express has three serial communication ports and one optional 10/100 Mb Ethernet I/P port. The system facilitates communication with other devices through widely accepted networks such as BSAP, TCP/IP open Modbus, serial Modbus, DF1, DNP3 and HART, which are all standard options within every unit. For open access to most HMI products, Emerson's flexible, easy to implement Bristol OPC Server is offered. ControlWave Express 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, process control functions, measurement, calculations and data storage. write your comments about the article :: © 2006 Construction News :: home page |
