2.產 品 詳 情 資 料：
WOODWARD 5466-041的主要功能是作為PM865硬件和軟件執行的監視器，這兩個模塊一起構成了一個符合IEC61508的SIL2標準的系統，由TüV認證。SM810運行SIL3認證的操作系統，例如：?雙重和反相存儲器?內部電壓雙重過電壓保護?兩個獨立的看門狗定時器振蕩器監控?固件和數據存儲上的CRC SM811與SIL2的SM810類似，但也可以與PM865一起構成符合IEC61508的SIL3的控制器，WOODWARD 5466-041。在具有S800高完整性模塊的高完整性系統中使用的ModuleBus電報使用長幀的概念。長幀是通過安全標頭擴展的ModuleBus電報，包括附加診斷數據和CRC32。發送至S800 I/O高完整性模塊的S800模塊總線報文使用來自PM865的數據和來自SM810/SM811的反相CRC32。I/O模塊檢查安全頭是否正確。通過ModuleBus從S800 I/O高完整性模塊接收的數據具有由SM810/SM811和PM865獨立驗證的安全標頭。安全標頭中的任何CRC32或其他故障將導致重試傳輸，如果重復，則會導致故障S800 I/O高完整性模塊關閉。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
