Abstract
Apparatus for controlling a downhole device in a well has a body with a control slot and pin movable in the slot. The slot has a first inactive loop in which the pin can cycle between different idling configurations, and a second active loop in which the pin can move between different configurations which correspond to active and inactive configurations of the downhole device. The pin can be switched between the first and second loops, and can cycle between the different configurations within without switching between the different loops. The slot can be provided on a piston, and the axial movement of the piston in the bore can drive the relative movement of the pin and the slot.
