Hello,

Yes in SIL, either one option as I remember is to make your application as first NON-SIL,make the modification in PLC Hardware tree IO property as INVERTED, and then again convert it to SIL.

Second,program where you are generating and Connecting your that DO.

Use another boolean Tag there,make your Block FB output parameter as Inverted inside your Library block only.

Connect new tag instead of direct DO, use MOVE block and do the desired modification for NEGATE/INVERT. And,then move that your Negated output to DO IO
