43、principles for high availability networks that meet the requirements for industrial automation networks. In the fault-free state of the network, the protocols of the IEC 62439 series provide ISO/IEC 8802-3 (IEEE 802.3) compatible, reliable data communication, and preserve determinism of real-time da

44、ta communication. In cases of fault, removal, and insertion of a component, they provide deterministic recovery times. These protocols retain fully the typical Ethernet communication capabilities as used in the office world, so that the software involved remains applicable. The market is in need of

45、several network solutions, each with different performance characteristics and functional capabilities, matching diverse application requirements. These solutions support different redundancy topologies and mechanisms which are introduced in IEC 62439-1 and specified in the other Parts of the IEC 62

46、439 series. IEC 62439-1 also distinguishes between the different solutions, giving guidance to the user. The IEC 62439 series follows the general structure and terms of IEC 61158 series. The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that complianc

47、e with this document may involve the use of a patent concerning a full-duplex Ethernet in which each device periodically transmits a message representing its connectivity to the other devices , allowing them to choose a redundant path in case of failure, given in 7.1 and 7.3. IEC takes no position c

48、oncerning the evidence, validity and scope of this patent right. The holder of this patent right has assured the IEC that he/she is willing to negotiate licences either free of charge or under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respec

49、t, the statement of the holder of this patent right is registered with IEC. Information may be obtained from: Fieldbus Foundation 9005 Mountain Ridge Drive Bowie Bldg Suite 190 Austin, TX 78759 USA Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above.
