Dear MDehshat, I think, that you want to calculate the SIL of your entire plant, don't you? In this case you have to find out all risk factors, which your system could bring, how often they appear and how you can avoid them. This will be the input for the SIL-calculation of your system. The PFD / PFH - values of the CPU / SM are only a part of the entire calculation. More information about Functional safety and the IEC61508 are available on http://www.iec.ch/zone/fsafety/fsafety_entry.htm Regards, yy1 |

Dear MDehshat, I think the 'Safety Evaluation Tool' could help you: http://www.automation.siemens.com/cd/safety/html_76/produkte/si_normen/tool.htm Regards, yy1 |
