PURPOSE:To enable number change of slave station simply through operation at the setting section of a central processor, when the number of consumer increases or decreases, by inputting relation between the position number of slave station and the slave station number through the setting section thereby modifying arrangement of current information, transfer trip signal, and the like. CONSTITUTION:When the number of consumer changes from 3 to 4, SUB No(SUB4) of slave is added. At the same time, number of terminal of a central processing unit(not shown in the figure) is changed from 3 to 4, and SUB 4 circuit is added. Furthermore, relation between position No and slave station is inputted through a setting section(position No.1= SUB1, position No.2=SUB2, position No.3=SUB3 are changed to position No.1=SUB1, position No.2=SUB4, position No.3=SUB2, position No No.4=SUB3).
