Associating controller with sensors or actuators e.g. for motor vehicle level regulation system - successively polling outputs from controller while monitoring sequence of activation and responses of sensors associated with magnetically-controlled hydraulic cylinders to learn association

The outputs (1-4) of the controller are connected to the magnetic valves (B,A,C,D) controlling hydraulic cylinders (HA,HB,HC,HD) equipped with sensors (HA,HB,HC,HD) which are linked to corresp. inputs (a,b,c,d) of the controller. The variation of the state of each valve is communicated to the controller from the appropriate sensor. The control outputs are associated with the actuator inputs by successive addressing while the activated control inputs are ascertained. After polling all outputs, the controller learns the pairings of the outputs and actuator inputs. ADVANTAGE - Costly component marking for assembly is unnecessary and equipment is assembled easily.
