Abstract
Idle messages are transmitted by an expansion node into the ring topology until the first idle message arrives to the expansion node after having passed through the entire ring. Frames may then be transmitted by the expansion node at every cycle time. The expansion node has an expansion buffer that may receive incoming frames and stores the frames until the next cycle time. The frame stored in the buffer may then be transferred to transmission side of the expansion node and transmitted into the ring topology. If there is no frame stored in the buffer at the beginning of a new cycle time, the expansion node may generate a new frame and transmit the new frame into the ring topology.
