6.3. INV(Inverting):Inverting​

 

Symbol

Description

It reverses the result until Rung (activate ßà deactivate).

This process implements /(AxB)=/A+/B or /(A+B)=/Ax/B according to the law of De Morgan, so it can simply form AND logic without branches instead of using OR logic with many branches.

Therefore, as (R1+R2+R3) = /(/R1x/R2x/R3), both of two below logics will have same results.
