Abstract:

A master apparatus (100) and a slave apparatus (200) participate in a token passing, while an IO apparatus (300) does not participate in the token passing. The IO apparatus (300) transmits, to the master apparatus (100) and slave apparatus (200), a SendPermitRequest frame that informs, as data transmission schedule time, a time at which the IO apparatus (300) is scheduled to transmit data. If the data transmission schedule time comes while the master apparatus (100) and slave apparatus (200) hold the token, the master apparatus (100) and slave apparatus (200) transmit, to the IO apparatus (300), a SendPermit frame that gives a data transmission right.
