HARTING Ethernet Cabling – 4-polesIntroductionB·16The chapter on „HARTING Ethernet Cabling – 4-poles” describes the complete HARTING product linefor installing Ethernet cabling at machines, plants andproduction facilities in an industrial environment.The product line includes: - versions, designed for on-site assembly versions ersin IP 20 and IP 65 / IP 67 versions The four-wire cabling is specially designed forEthernet transmission of data with a max. transmissionrate of 100 Mbit/sec.Data can be reliable transmitted at either 10 Mbit/sec.or 100 MBit/sec., with the clear assignment of the tactsof the RJ45 connector. 10Base-T 100Base-T (Fast Ethernet)Cabling components based on the M12 D-codingsystem are also a part of the four-wire cable productline, since both RJ45 and M12 connectors are commonin automation engineering.In addition to IEEE 802.3 Ethernet, the followingEthernet-based Fieldbus applications, with or withoutreal-time functionality, can be transmitted (not acomplete listing): according to IEC 61784-5-3 This type of cabling is driven by the progressiveimplementation of various Fieldbus systems onEthernet platforms.The special requirements placed on the cabling areoften developed by manufacturing companies anduser organizations. These requirements sometimescationsand networks.Withal these somewhat proprietary trends indevelopment, there is also a movement towardsinternational standardization, for example withinthe IEC SC65C committee.
