USC-8000 面向安全设计


安全状态定义:控制器IOBUS静默、DI/AI上报0、DO不输出、AO输出0mA

核心设计:1oo2架构可以在单故障下执行安全功能

关键设计:针对故障的诊断,对失效的处理

通信设计:用于连接控制器和IO模块的IOBUS

工程软件:针对功能安全的反编译和对比

认证边界:控制器、IO模块、 IOBUS 、Workbench

可靠性:针对功能安全是高可靠的,常规应用下的可靠性指标不能直接引用功能安全分析的结果

检修要求:一年一次,目的是对DU(不可诊断危险失效)进行测试。


USC-8000 面向非安全设计


背景:安全和非安全混合在一起使用的情况下,安全对于非安全的应用有各种限制,例如:故障后输出的状态、输入接线、写控制器内部变量等。

实现:基于通信板卡

数据中心:实现不同数据的汇集和交换。

边缘计算(开发中):采用高级语言对数据进行边缘处理,python。

可编程控制(开发中):常规PLC

可编程网关(开发中):不同协议实现数据交换,并且对数据进行处理,比如:bit合并,数值缩放等。
