康涅狄格州Watertown市4月2日新聞――艾默生過程管理公司宣布擴展Bristol® ControlWave® Micro Hybrid RTU以太網I/O。擴展的Micro RTU擁有雙以太網端口不需外部路由器現在即可支持更多的應用。 新型雙端口以太網CPU和I/O擴展CPU允許主機通信和擴展I/O通信分離，這種配置的優(yōu)點是運用以太網高速鏈路連接到擴展/遠程 I/O裝置，最快提升速度，使寬帶連接到控制I/O。 Bristol ControlWave Micro Hybrid /RTU基于世界編程和通信行業(yè)標準，是一個靈活的控制器，為所有能源行業(yè)，水行業(yè)和廢水處理行業(yè)的遠程測量，控制和SCADA應用提供高性價比和高性能值。ControlWave技術用于降低全球成千上萬的遠程自動化應用的工程成本，提高操作效率。 ControlWave Micro可擴展到多達十四個I/O插槽，對于帶更多I/O接口的應用，新型雙以太網接口CPU可以和許多I/O智能插槽擴展器連接，每個CPU可連接多達十四個I/O插槽，I/O智能插槽擴展器可以與主控制器本地連接，也可以遠程連接到任何銅導線或無線以太網IP，該功能降低了維修時間和成本，因為只有主控制器運用控制和通信編程。 I/O智能插槽擴展器有一到十四個可選擇的插槽，因此分布式I/O可以按照每個位置的要求定制尺寸。ControlWave Micro I/O為非常經濟實惠的分布式I/O解決方案提供多種混合式數字和模擬輸入和輸出I/O模塊。 以太網端口作為一個凈增值，通過集成Modbus TCP/IP，DNP3 和 CIP 協(xié)議還可以用于介入第三方設備，甚至串行協(xié)議可以在IP通信結構內部穿過以太網端口到達一個遠程終端，在這里信息自動轉換成串口格式。 艾默生公司的Bristol ControlWave設計編程軟件符合PLC編程IEC 61131-3國際標準。設計家支持所有五種IEC 61131-3編程語言，并加強了功能強大的ACCOL III過程控制功能模塊，該模塊允許運用單一控制器控制邏輯和過程控制功能，測量，計算和數據存儲。工程師還可以研發(fā)自己的可以再次使用的功能模塊，進一步降低工程時間和成本。通過RTU內的計時打印報警和歷史文檔存儲進一步加強了這些功能，提供最完整的數據。通信失敗則數據自動恢復。 original text [COLOR=#708090]Emerson expands Ethernet I/O of Bristol® ControlWave® Micro Hybrid RTU to support larger applications WATERTOWN, CONN （April 2, 2007） — Emerson Process Management announces Ethernet I/O expansion for the Bristol® ControlWave® Micro Hybrid RTU. The expanded Micro RTU now supports larger applications with the new dual Ethernet ports that provide network segmentation without the need for external routers. The functionality is provided in new Dual Port Ethernet CPU and I/O Expansion CPUs that allow separation of host communications from expansion I/O communications. The advantage of this configuration is dedicated connectivity to expanded/remote I/O installations using the speed of an Ethernet backbone, maximizing the speed and bandwidth available to Control I/O. Based on worldwide industry standards for programming and communications, the Bristol ControlWave Micro Hybrid /RTU is a flexible standards-based controller offering exceptional price/performance value for all remote measurement, control, and SCADA applications 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. The ControlWave Micro base chassis is expandable with up to fourteen slots of I/O. For applications with larger concentrations of I/O, the new Dual Port Ethernet CPU allows communication with several I/O Expansion chassis, each with up to fourteen I/O slots. I/O Expansion chassis may be local to the main controller or remote anywhere with copper or wireless Ethernet IP connectivity. This capability reduces engineering time and cost because only the main controller is programmed with the control and communication strategy. I/O expansion chassis are available with a selection of one to fourteen slots so the distributed I/O may be sized for each location’s requirement. ControlWave Micro I/O offers a variety of mixed digital and analog input and output I/O modules for an extremely cost effective distributed I/O solution. As an added value, the Ethernet ports can also be used to interface to third party devices through the integral Modbus TCP/IP, DNP3 and CIP protocols. Even serial protocols may ’tunnel’ through the Ethernet port, within an IP messaging structure, to a remote terminal server where the messages are automatically converted back to serial format. Emerson’s Bristol ControlWave Designer programming software is compliant with the IEC 61131-3 international standard for PLC programming. Designer supports all five IEC 61131-3 programming languages and 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. 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 RTU to provide maximum data integrity. This data is automatically recovered following a communication failure. [/COLOR]
