A transmitting system is provided in which a logical address may be set without fail and which may be good for branches of transmitting paths. The transmitting system includes a controller that may send a command message for setting an address and a plurality of transmitting modules connected in cascade to a pair of power transmission and communication lines extending from the controller. The transmitting module is composed of a switching element circuit and a signal processing circuit. The switching element circuit may open and close between input and output terminals in response to an opening/closing control signal SCTL. The signal processing circuit gives an opening control signal SCTLO to the switching element circuit when a non-set address is set in the address setting means and set the logical address from the controller to the address setting means to give a closing control signal SCTLC to the switching element circuit when a polling address of an address setting command message is identical with the non-set address set in the address setting means. <IMAGE> |
