ABB 81EA11D-E GJR2374800R0210 模拟量输入模块

【产品详情】

ABB 81EA11D-E GJR2374800R0210 模拟量输入模块在系统体系结构上，从传统的单机向多CPU和分布式及远程控制系统发展；在编程语言上，文本化和图形化的语言多样性，创造了更具表达控制要求、文字处理、通信能力的编程环境。

从应用范围和应用水平上，除了继续发展机械加工自动生产线的控制系统外，则是发展以PLC为基础的DCS系统、监控和数据采SCADA系统、柔性制造系统（FMS）、安全联锁保护（ESD）系统、运动控制系统等，全方位地产提高PLC的应用范围和水平。

进入90年代后期，由于用户对开放性的强烈要求和压力，由于信息技术的大力推动，PLC如果还停留在原有的专用而又封闭的系统概念上，它将坐以待毙。于是PLC进入了其发展的第四阶段。其特征是：

在保留PLC功能的前提下，采用面向现场总线网络的体系结构，采用开放的通信接口，如以太网、高速串口等。

【英文介绍】

ABB 81EA11D-E GJR2374800R0210 analog input module in the system architecture, from the traditional stand-alone to multi-CPU and distributed and remote control system development; In terms of programming languages, the diversity of textual and graphical languages has created a programming environment with more expressive control requirements, word processing and communication capabilities.

From the application range and application level, in addition to continuing to develop the control system of mechanical processing automatic production line, it is the development of PLC-based DCS system, monitoring and data acquisition SCADA system, flexible manufacturing system (FMS), safety interlock protection (ESD) system, motion control system, etc., to improve the application range and level of PLC in an all-round way.

Into the late 1990s, due to the user's strong requirements and pressure on openness, due to the strong promotion of information technology, if the PLC still stays in the original dedicated and closed system concept, it will be waiting for death. So PLC entered the fourth stage of its development. Its characteristics are:

Under the premise of retaining the PLC function, the architecture oriented to fieldbus network is adopted, and the open communication interface is adopted, such as Ethernet and high-speed serial port.
