The four constant kitControl components are:

Each object simply provides a linkable status-type output value, and offers a default “Set” action for changing that value (in the case of the BooleanConst object, two default actions are “Active” and “Inactive”). A constant object may be handy when the same target property of multiple components needs to be adjusted simultaneously. Constants may also help clarify logic on a wire sheet.

Constant components are far simpler than writable control points (no priorities, status processing, and so forth).
