PURPOSE:To automatically select and control plural slave stations from a master station only through one operation by providing the master station with a memory means that groups the slave stations and stores them. CONSTITUTION:A memory device 12 in the master station 1 groups the slave stations 2-1-2-n and stores them. Namely, said equipment arbitrarily sets the number of groups of slave stations to which an operator wants to automatically select and control in the following format: the number of processed stations/ station (a)/station (b).../station (n). Consequently, by controlling the set data, all the groups of slave stations can be automatically selected and controlled only through one operation. Thus operation time can be shortened, and operational errors can be prevented.
