In order to provide a method for reliably detecting that an operation device, such as a sensor or an actuator, is connected to a proper connector of a control device, a connection detecting method includes the steps of reading an identification signal of the operation device, comparing the identification signal with a predetermined signal assigned to the operation device at the control device, and determining if the identification signal matches the predetermined signal. The system also includes a step of sending a connection failure warning after the determining step is repeated for predetermined times.
