ABSTRACT:
A communication control device receives and transmits control data and/or communication data through a ring communication network. The apparatus comprises a wait time decision unit for deciding, according to a state of the network, a wait time for detecting a reception of the control data circulating through the network; a wait time holding unit for holding the wait time decided by the wait time decision unit; and a time counting unit for counting time from a reception of the control data and providing a broken control data report signal if the control data is not again received within the wait time.
