2) Valid for averaged ambient temperatures up to 40 °C (104 °F) in accordance with general standard for devices
with SIL capability.
3) PTC = Proof Test Coverage (diagnostic coverage achieved by device failure detection during manual proof testing)
4) This value takes into account all failure types of the electronic components as per Siemens SN29500
5) All diagnostic functions are executed at least once during this time.
6) Maximum time between fault detection and fault response.
7) The process safety time is the diagnostics test interval * 100 (calculation according to IEC 61508).
8) MTTFd as per ISO 13849/IEC 62061 also includes soft errors (sporadic bit errors in data memories).
