Appendix
D
Safety Data
This appendix lists calculated values for probability of failure on demand (PFD),
probability of failure per hour (PFH), and mean time to failure (MTTF). PFD
and PFH calculations comply with IEC61508, edition 2, 2010.
Calculated values of probability of failure on demand and probability of failure
per hour appear in the table and must be calculated for the devices within the
system to comply with the SIL level required for application.
Users must be responsible for following the requirements of ISO 13849-1:2008,
to assess performance levels in their safety system.
Within the proof test interval, every I/O module must be functionally tested by
individually toggling each input point and verifying that it is detected by the
controller.
Additionally, each output point must be individually toggled by the controller
and user-verified that the output point changes state.
For more information, refer to these publications.
