Using soft key in a SIL3 AC800 HI app
I have a softkey input to a Sil 3 app ( motor start). I want to use a function block to implement it . When using SDbool i need to be a safety operator role which imply the security message to use the softkey.
Is there any other way ( or another function block ) to be used without the safety op role required.

Just use a signal from a Non SIL application and send that to the SIL application with diagram etc.
Obviously this is only allowed if the Motor Start signal is NOT part of a SIL loop. Normally the start of motors, sequences etc are not classed as SIL but this is application specific and must be clarified in a case by case basis.
