Chapter 1

PFH and PFDavg Data

The information in this document has been compiled as part of the AADvance Eurocard IEC 61508 certification, the failure modes and Failure Mode Effect and Diagnostic Analysis (FMEDA) of each module having been inspected and verified by an independent certification body.

The tables provide failure rates and PFH & PFD avg data for AADvance Eurocard Controller used in applications with an 8 or 24 hour MTTR and with 6 months, 1 year, 5 years or 10 years Manual Test Interval (MTI). If the AADvance system is to be used in an application with any other MTTR or MTI, use the data from the next column with a higher MTTR or MTI than that of the application.

If a de-energize to action system is configured to provide a shutdown on the first fault, the MTTR has a negligible effect, hence, the tables in the PFD Data can be used for any MTTR.

System Configurations The PFH and PFD calculations are derived from IEC 61508 Section 6 and the examples below show how the calculations are used to define the probability of failure for a Safety Instrumented Function.

Example 1 This illustrates a SIL3 SIF with one signal input and one signal output; it has a MTI of 1 year and a MTTR of 8 hours, it is configured as a de-energized to trip arrangement.

Module Module Description SFF de HFT SFF e HFT

NOTE The examples show standard AADvance modules, however. the same calculations are used for Eurocard modules and Eurocard values have been used in these calculations.

NOTE The Soft Error values used to calculate PFD/PFH figures are, in line with industry common practice and JESD89a, calculated with Neutron flux values at sea level (NY,NY).Values measured at high altitude would be expected to yield worse values. Similarly subsea applications are likely to experience lower values of Neutron flux.Contact Rockwell Automation for additional information.



Refer to the Table 4.

Example 2 This illustrates a SIL 3 SIF with 2 inputs on dual input modules and 1 output with an MTI of 1 year and MTTR = 8 hours, configured as 1oo2 de-energize to trip.

Refer to Table 4.

Example 3 SIL3 SIF with 2 inputs on dual input modules and 1 output with a MTI of 1 year and MTTR = 8 hours as 1oo2 de-energize to trip.



Refer to Table 4.

Example 4 This illustrates a SIL 3 with 1 dual input and 2 outputs, with a MTI of 1 year and MTTR = 8 hours, configured as 1oo2 de-energize to trip.

Refer to Table 4.



Example 5 This illustrates a SIL 3 SIF distributed between two controllers, with one signal input and one signal output; it has a MTI of 1 year and a MTTR of 8 hours, it is configured as a de-energize to trip arrangement.

Refer to Table 4.
