Tutorials using Cond. Fill (Multi-Bool)

What Cond. Fill (Multi-Bool) does

Several booleans, in priority order, plus a fallback colour. The first row whose parameter is true wins; if none is, the fallback applies.

That ordering is the point, and it is what makes this the right binding for real plant state. Faults sit at the top, because a fault must beat a position. Limit switches sit below, because open and closed only matter while nothing is wrong. And “neither limit made” needs no row of its own — it is what the fallback covers, which is how two limit switches give you four states from two parameters.

So choose the fallback deliberately. It is a state the operator will see rather than an error colour: on a valve it is travelling, on a hopper it is between levels.

Rows are read top to bottom, so reordering them changes behaviour. If two can be true at once — and in a plant they will be — the higher one is the answer, every time. Each row’s colour can be fixed or supplied as a parameter, independently of the others.
