I need to create SR ,RS block because I am using sil2 block. SR,RS basic block is sil3.
My basic SR ,RS block is sil3 ,I can't convert to sil2 bcos tat is basic library block .how to I create sil2 SR ,RS BLOCK.
You can use SIL3 blocks in SIL2 applications and SILx in non-sil applications.
I would suggest a basic working knowledge of SIL and safety instrumented systems would be a good thing to have before taking on the responsibility of designing SIL compliant software.
