Non SIL Feedback signals for a SIL3 Valve
The feedback signals for a SIL3 SDValve are Non SIL. I have created Communication variables from Non SIL to SIL but not able to connect to the ports FBOpen and FBClose of the SDValve block. it shows error "Error 1765 : Not Allowed to be modified"

Hi
The SDValve is a bit strange. If you absolutely need the feedback in the SIL application I think you can create a new Global variable (BoolIO).
Write the value from the nonSIL to the new global. Connect the global variable to the valve block.
gOpenFB.value := CommVar;
Valve block:
FBOpen := gOpenFB;
Hope it works
