Abstract:
An automatic tree structure address setting method of setting addresses in respective relay units of a plurality of relay units of a plurality of relay units connected to construct a tree structure, comprising the steps of:a) selecting respective child relay units in a predetermined order if at least one child relay units is connected to a respective relay unit;b) increasing an address, and then setting the increased address in one selected child relay unit;c) repeating step a) to step b) with respect to the selected child relay unit until an address of a most downstream relay unit is set;d) repeating step c) until the setting of address of all child relay units has ended in a relay unit positioned just before a most downstream relay unit in an upstream path; ande) repeating step c) to step d) until the setting of all child relay units has ended in a relay unit positioned second before the upstream relay unit in an upstream path if address setting of all child relay units has been ended in the relay unit positioned just before the most downstream relay unit.
