摘要

The redundant Ethernet connection has a switch matrix (19,20), which is inserted between data receiving unit (1,2) and transmission circuits (29,30). The switch matrix has two data inputs (25,27) for the transmission circuits and a data output (15,18) for data receiving unit. The switch matrix recognizes an arising error and subsequently switches the switch matrix-data output to another switch matrix-data input with functional transmission circuit during the data communication over switch matrix-data input connected with the switch matrix-data output.
