    Abstract: A communication system includes a primary apparatus and a plurality of secondary apparatuses connected in a daisy chain to the primary apparatus. In each of the secondary apparatuses, a detecting unit detects a current. In response to a switching unit being in an on state, the switching unit allows a current from a primary apparatus to be applied to a detecting unit of at least one other secondary apparatus that is positioned further toward the primary apparatus side than own secondary apparatus is. In response to the switching unit being in an off state, the switching unit allows the current from the primary apparatus not to be applied to the detecting unit of the at least one other secondary apparatus and the detecting unit of the own secondary apparatus. A secondary control unit sets an ID of the secondary apparatus based on a detection result of the detecting unit.
