Description
This APP allows the SIL (PFD and RRF) calculation of a SIF modelled as input+logic solver+output. It also calculates the MTTFs as per ISA-84 formulae. The inputs for the calculations are the failure rates in FIT (the app provides a converter from flr/hrs) and a simple wizard to calculate Lambdas from PFD, Proof test interval and MTTF. Addittionally it calculates, given the HFT and the SFF, the architectural constraints supporting both IEC-61508 and IEC-61511 tables. The APP can save and restore csv backups.* text size issue fixed * ability to select A type for logic solvers* possibility to save/load individual devices (in, logic solver or out)* MooN approximate calculation for both PFD and MTTFs

Excellent App.
As simple as useful... must to have!
Easy to use and straight forward.
It is very handy to have one......hope to update with latest inclusion/ exclusion of respective STD reference
Must have, nice and easy to use
