PURPOSE:To automate the number setting to facilitate addition, change, and removable of slave machines, by cascading all slave machines and turning on respective internal switches of slave machines successively in a slave machine number setting mode to set numbers to slave stations. CONSTITUTION:One master machine M as a central controlling part and plural, for example, N-number (N is an integer >=2) of slave machines S1-SN as terminal equipments are connected in series successively through internal switches 13 of slave machines. A control circuit part 15 is connected to the first input/ output terminal 11 of each slave machine S, and turning-on of the internal switch 13 is controlled by this control circuit part 15. A set number set by the master machine M is stored in the control circuit part 15; and when this set number is designated and an internal switch turn-on control instruction is given, the internal switch 13 is turned on. |
