How can I check that unselected object is active or not by Makinom node?

the object to check is at the Hierarchy but there is not selected by player.

Depends on which game object it is.

Beside the available objects (e.g. player, machine object, etc.), you can also define actors in the Settings node of the schematic - they're also available in this selection when set up.
E.g. the Game Object actor type allows you to select a game object from the scene in your machine component using the schematic.

You can also search for game objects by name or tag, but disabled game objects can't be found by Unity, so using a directly referenced game object (via Game Object actor) is probably the best way.
