2.产 品 详 情 资 料：
WOODWARD 5466-041的主要功能是作为PM865硬件和软件执行的监视器，这两个模块一起构成了一个符合IEC61508的SIL2标准的系统，由TÜV认证。SM810运行SIL3认证的操作系统，例如：•双重和反相存储器•内部电压双重过电压保护•两个独立的看门狗定时器振荡器监控•固件和数据存储上的CRC SM811与SIL2的SM810类似，但也可以与PM865一起构成符合IEC61508的SIL3的控制器，WOODWARD 5466-041。在具有S800高完整性模块的高完整性系统中使用的ModuleBus电报使用长帧的概念。长帧是通过安全标头扩展的ModuleBus电报，包括附加诊断数据和CRC32。发送至S800 I/O高完整性模块的S800模块总线报文使用来自PM865的数据和来自SM810/SM811的反相CRC32。I/O模块检查安全头是否正确。通过ModuleBus从S800 I/O高完整性模块接收的数据具有由SM810/SM811和PM865独立验证的安全标头。安全标头中的任何CRC32或其他故障将导致重试传输，如果重复，则会导致故障S800 I/O高完整性模块关闭。WOODWARD 5466-041
The main function of the SM810 is to act as a monitor for the HW and SW execution of PM865 and these two modules together are a SIL2 compliant system according to IEC61508, certified by WOODWARD 5466-041. The SM810 is running a SIL3 certified operating system and have a high degree of self-diagnostic including, for example: • Double and inverted memory • Double over voltage protection on internal voltages • Two independent watchdog timersOscillator supervision • CRC on firmware and data storage An SM811 operates like an SM810 for SIL2 but can also together with the PM865 form a controller compliant with SIL3 according to IEC61508, certified by TÜV. The ModuleBus telegrams used in a High Integrity system with the S800 High Integrity modules use the concept of long frames. Long frames are ModuleBus telegrams that are extended with a safety header, comprising additional diagnostics data and CRC32. S800 ModuleBus telegrams sent to the S800 I/O High Integrity modules uses data from the PM865 and an inverted CRC32 from the SM810/SM811. The I/O module checks that the safety header is correct. Data received from the S800 I/O High Integrity modules over the ModuleBus have the safety header independently verified by both SM810/SM811 and PM865. Any CRC32 or other faults in the safety header will result in a retry transmission and, if repeated, a shutdown of the faulty S800 I/O High Integrity module.WOODWARD 5466-041
