Chapter 1

PFH and PFDavg Data

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

The tables provide failure rates and PFH & PFD avg data for AADvance 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

Chapter 1 PFH and PFDavg Data

PFH Data The following table provides the probability of failures per hour for both energize to action and de-energize to action for SIF configurations designed for High Demand applications.

Table 11 - PFH Data

Binding and Peer-to-Peer Communications Data

The PFH and PFD values for the Bindings and Peer-to-Peer Communications Data for each segment are as follows:

• PFH = 1E-11• PFD = 1E-7

Safe Failure Fraction (SFF) and Hardware Fault Tolerance (HFT)

The following table provides the SFF and HFT data for SIF configurations energize to action and de-energize to action mode.

SFFde applies to a normally energized system that is de-energized to action.

PFH and PFDavg Data Chapter 1

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.

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.
