Filed: 1984-04-20
Abstract: PURPOSE:To improve the overall efficiency of a system where plural stations are used with a certain station defined as a master station to give polling successively to other slave stations and these slave stations give answers for data communication, by defining a certain slave station as a temporary master station to give polling to other slave stations in case the original master station is incapable of polling. CONSTITUTION:When a master station is incapable of polling by some reason, other slave stations detect this fact and decide automatically a tempoary master station. After a power supply is applied, the proper value is set at a time A26 by a timer start signal 27 through a timer setting part 1. Then a command reception check part 2 checks whether or not the polling or response given from another station is received by a signal reception part A21. When an affirmative result is obtained, a slave station 3 is decided. While the time is counted by a counting part A if no affirmative answer is obtained. Then a time-out check part 5 checks the time-out state. When an affirmative result is obtained, a master station 6 is decided. Then the polling 29 of the master station is given to other stations.
