Page 6: Planning
SAFETY MANUAL SIL K*D0-SD*-(EX)*.****(.SP), HIC2871 Planning Planning System Structure 2.1.1 Low Demand Mode If there are two loops, one for the standard operation and another one for the functional safety, then usually the demand rate for the safety loop is assumed to be less than once per year. -
Page 7: Assumptions
SAFETY MANUAL SIL K*D0-SD*-(EX)*.****(.SP), HIC2871 Planning Assumptions The following assumptions have been made during the FMEDA analysis: Failure rate based on the Siemens SN29500 data base. The stress levels are average for an industrial environment and can be compared to the Ground Fixed Classification of MIL-HNBK-217F. -
