Multiplex transmission method
摘要:
In a multiplex transmission method, refresh transmission operations at a predetermined period, and event transmission operations are time-divisionally performed in a multiplex transmission mode, and a predetermined non-transmission time is set before start of each refresh transmission operation. When another transmission operation is performed within the non-transmission time, a communication is performed, while the predetermined period of the refresh transmission operations is properly permitted to be delayed to assure the non-transmission time for such a communication state.
