<p><P>PROBLEM TO BE SOLVED: To reduce the repetition of unnecessary calls and a wasteful waiting time between a master unit and a slave unit. <P>SOLUTION: The slave unit 2 has a transmission and reception part 3 which transmits and receives data to and from the master unit 1, a data error detection part 5 which determines whether data received by the transmission and reception part 3 include an error, and a receiving operation time control part 8 which changes a predetermined receiving operation time. Moreover, when the data error detection part 5 determines that the data include the error, the receiving operation time control part 8 extends a receiving operation time of the transmission and reception part 3 so as to receive data sent newly from the master unit 1. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
