Abstract: Disclosed are a positioning apparatus and a PLC system using the same. The positioning apparatus of the present invention generates, for every control period, a pulse signal for indicating the position of an object to be controlled, determines the current position of the object to be controlled using the pulse signal, and if the current position is a specific position, controls the object to be controlled in synchronization with the specific position.
