Abstract

PURPOSE:To make the assignment of transmission line average for station devices, by sequentially renewing the station device number of an inquiry command from a control station, in a system where a plurality of station devices are connected to a pair of transmission line. CONSTITUTION:Assuming that no station devices 41, 43 and 46 use a transmission line 1. If a control station 3 outputs a command RQP(#3) which inquires the request of use of the line 1, timings t0, t1- at each time T from the trailing of the command RQP(#3) can be recognized as the timings for the devices 43 and 44. Thus, the use of the line 1 is permitted to the station device 43, when the device 43 transmits the command RQP(#3) in the timing of t0. When the end of use is detected by a control station 3, since a signal having only one renewed number such as command RQP(#4) is transmitted, the use of the transmission line 1 with equality is possible.
