Abstract

PURPOSE:To transmit multiple address communication data as low order and high order multiple address communication data to a high hierarchy and low hierarchy transmission lines by fetching the multiple address communication data flowing to the high order hierarchy and low hierarchy transmission line via an interface and editing it. CONSTITUTION:The high order multiple address communication data from high order A-C equipments 2-4 of a high order hierarchy transmission line 1 is edited to a low order mltiple address communication data by a setting data, which is stored in a memory 9c via a high order transmission interface 9a. Then a CPU 9d edits the set data in the memory 9c into a low order multiple address communication data and it is sent from the low order transmission interface 9b to the low order transmission line 5 and the low order A-C equipments 6-8 receive the data. Moreover, in editing the low order multiple address communication data to the high order multiple address data, it is executed similarly as above by a transmission coupler 9.
