产品详细资料
如果需要增加输入的容错性,也可以配置三输入模块布置。当配置三输入模块布置时,输入模块在无故障条件下以2oo3D运行,在检测到任何模块中的个故障时降级至1oo2D,然后在检测到任意两个模块中的故障时降级为1ooD,并且当所有三个模块都有故障时,将失效安全。处理器将在无故障条件下以1o2D运行,在任一处理器模块出现次故障时将降级至1o1D,并且当两个处理器模块都出现故障时,处理器将失效安全。对于高需求应用,除非安全要求规范(SRS)中定义了补偿措施并记录在操作程序中,否则应用程序必须设计为在MTTR内未更换因危险故障导致的模块故障时关闭安全仪表功能。
A triple input module arrangement can also be configured if it is required to increase the fault tolerance of the input. When a triple input module arrangement is configured the input modules operate in a 2oo3D under no fault conditions, degrade to 1oo2D on detection of the first fault in any module, then degrade to 1oo1D on the detection of faults in any two modules, and will fail-safe when there are faults on all three modules. The processor will operate in 1oo2D under no fault conditions, will degrade to 1oo1D on the first fault in either processor module and will fail-safe when there are faults on both processor modules. For high demand applications, unless compensating measures are defined in the Safety Requirements Specification (SRS) and documented in operating procedures, the application program must be designed to shut down safety instrumented functions if a module failure due to a dangerous fault has not been replaced within the MTTR.
