Abstract
A system is provided for remotely controlling a downhole tool in a well. A plurality of substantially identical command signals are transmitted into the well. Each of the command signals is received at the downhole tool by a controller having information stored therein identifying an operative command signal signature associated with that tool. Upon comparing each command signal to the stored information and confirming that the command signal contains the operative command signal signature associated with that tool, a control signal is generated by the controller for each confirmed command signal. An operating element of the downhole tool is advanced one position in a repeating series of operational positions in response to each successive control signal generated by the controller.
