工程自动化方案

将应用于工程自动化的系统划分为适合于每个工厂的小型系统（水处理、焚烧、化学、纤维等），分别执行作用；中央监控单元和子单元系统连接到高速网络以形成一个集成系统。晓星重工业的工程自动化方案，在水处理、工厂和一般工业领域拥有30多年的系统建设经验，在国内外市场提供了100多次系统供货，满足了多样顾客需求。

特点及优点

即时性: 使用高速（100MbPS）串行通信，称为TC(Time Critical)-net I/O loop。; 在专用处理器内部使用IEC61131-3语言执行高速控制。; 同时满足高速顺序控制左旭的多维复杂标签（tag）和高速机械控制
可信度及稳定性: 以小单位系统分散控制功能，最大限度减少发生异常时的影响; 实现模块富余，并在内存中有一个内置的纠错电路
整体运作: 将分布式系统集中在中央系统中，用于各种数据处理和灵活管理。; 提供国际标准连接，可兼容Modbus、Profibus等通用工业串行协议
用户便利性: 在中央系统中，有几种类型的屏幕配置可用于过程控制。; 内置复杂演算、数据收集、报告功能，即使增加个别系统，也能轻易连接; 通过标准工程工具，控制命令简化过程，可实现简单的工程操作。
