Converting LD to FBD

How would I create the following in Function Block?

I'm using Unity Pro but if you can show me an example in any logic software, I can build it in Unity.

Basically if EFV (Effluent valve) is closed, I want a ZERO value to be transferred. If it's not closed, I want it to show the NTU value but I need to work off of the same Input. In other words I don't have a EFV_Open contact to work with.

I'm having a hard time figuring out how to duplicate the NC contact portion.
