西门子控制系统特点：
1、良好的系统安全性和可靠性
系统的建立不破坏现有生产设备的成熟小闭环系统的运行。系统采用分布式网络结构，网络上任何一台设备发生故障不影响其它设备的运行。
2、系统具有完备的自诊断能力。
PLC设备对PLC本身和IO口均具有自诊断能力。网络通讯系统均有检验和应答功能以及自诊断功能以保证通讯传输中的正确性。
3、计算机设置WATCHDOG技术防止程序“跑飞"。
系统构成的所有硬件均采用国内外公司的产品，这些产品在国内许多企业已广泛使用，实践证明它们是成熟的产品。控制室采用触摸屏系统平台，为全自动化改造的计算机联网提供了良好的外部环境，同时也给公司的全面计算机管理创造了条件。监控软件支持全局数据共享，每一台新增的工作站都可以获得所有数据而无须进行复杂的系统规划;开放性的软件设计使得用户能轻松开发出第三方接口。
