A magnettarget assembly 1 comprises a target 2 consisting of a plurality of segments 2. The porous structure includes a first part intended to be in contact with a stoma organ and having a first thickness, and a second part having a second thickness greater than the first thickness, the first part including a surface intended to face the abdominal wall covered by a second film of anti-adhesive material. The rinserdryer housing defines a substantially closed rinserdryer chamber. The interface interrogates the motor to acquire status and diagnostic information by receiving commands from the controller, adjusts a voltage level to a desired level, outputs the voltage signal to command and control the motor, and receives a voltage response from the motor.
