According to error rate relatively high（The number of data message that is namely imperfect or erroneously being transmitted by the first communication connection
Amount）To recognize too poor transmission quality.
In the embodiment according to Fig. 2, network components 14a identifies that the be connected with control station 12b first communication is connected 15b
Failure.Which create failure message A, the failure message description failure of communication connection 15b and be sent to the message
Field apparatus 11a-c.Failure message A for example can be multi-broadcast message（Multicast-Nachricht）（Simultaneously namely
To the message that multiple recipients send）.Specifically, failure message A for example can be so-called according to SNMP（SNMP-Simple
Network Management Protocol, Simple Network Management Protocol）" Trap " message, or according to IEC61850
GOOSE message（GOOSE-Generic Object Oriented Substation Event）.Two kinds of message are all to many
The message of the report event that individual recipient sends, quickly and efficiently to announce the event of generation in a network.Should trigger
Each event of corresponding message can be parameterized by user herein.In this case in first network part 14a with
It is the event of triggering failure message A that the failure of the first communication connection 15a-c of control station 12a-c is parameterized.
The medium access control device 18 of field apparatus 11a-c receives failure message A.Known according to failure message A,
One network components 14a and control station（Specifically control station 12b）Between communication connection（Specifically communication connection 15b）Generation event
Barrier.Thus the redundancy triggered by respective medium access control device 18 in field apparatus 11a-c switches.Control is in respective matchmaker
The redundancy switch unit 20 that is included in Jie's access control apparatus 18 and disable（So far it is activation）First PORT COM
19a and activate（So far it is disabling）PORT COM 19b.Because two PORT COMs 19a, 19b and identical medium
Access control apparatus 18 are connected and therefore use identical MAC Address, so the switching can extremely rapidly（At several milliseconds
It is interior）And the articulamentum of the communication device 17b in each field apparatus 11a-c（The layer 2-3 of osi layer model）On carry out, and
The application component 17a of each field apparatus 11a-c is not interfered with.
Because（It is now activation）Second PORT COM 19b is connected with the second network components 14b, then can pass through in the future
The communication connections of second network components 14b and second 16a-c（Herein as a example by communicating connection 16b）Equipment at the scene（Herein for example
Field apparatus 11a）With control station（It is, for example, herein that the first communication broken down connects the control station 12b that 15b is related to）Between
Carry out data message D3Other communication.The the first communication connection 15b for breaking down can be changed or repaired afterwards, so that so
Switch for other redundancy possible in the future afterwards（When the second communication connection 16a-c breaks down）First network is provided again
The communications of part 14a and first connect 15a-c for using.
