Abstract
A network system (10) comprises a master device (5) and a plurality of slave devices (1, 2, 3), and those devices are serially connected to one another in such a way that the master device (5) comes to the most upstream side, thereby configuring an optical multidrop network which ensures data transmission and reception by optical communications among contiguous devices. Each of the slave devices (1, 2, 3) self-controls so as to be in such a state as not to receive data from any slave device on the downstream side when starting an operation, and the master device (5) controls the individual slave devices (1, 2, 3) sequentially from the upstream side to the downstream side in such a way that each slave device is capable of receiving data from a downstream side slave device.
