LÜTZE Ethernet Connectivity - Solutions from a single source The requirements placed on efficient manufacturing systems are becoming more and more complex. Increased networking between production and management means that more and more automation systems are requiring the use of PC-based controllers and Ethernet communication networks. Ethernet is the name of a widely used, standardised communication infrastructure with various communication media.Together with higher-level communication software, Ethernet is today the basis for a large number of industrial local networks. In contrast to...

Cables - A lot depends on them The classical Ethernet began with the coaxial cable.Today, new installations use only symmetric cables, so-called balanced cables, or fibre-optic cables. Copper cables Various types of copper cable are used.The term "symmetric cable" does not refer to the structure of the cable, but rather exclusively to its electrical characteristics and the signal transmission. The symmetrical transmission of a signal requires two conductors; full duplex thus requires four conductors. A 10/100MB Ethernet cable that is suitable for industrial use will thus have at least four...

Pin assignment The most commonly used Ethernet connector is the so called RJ45 connector, which is available in shielded and unshielded variants. Of the RJ45 connector's eight pins, four are used for 10/100MBit/s, and all eight for 1000MBit/s. Colour coded according to EN 50173 - hard wiring In the EN 50173 standard, two colour codings are defined for installation, namely T568A and T568B. The user is free to choose between them, but should ensure during installation that the selected coding is maintained throughout the entire installation. Mixing the two codings will result in malfunctions...

7 Fibre-optic cables The advantages of fibre-optic cables are clear: wide bandwidth, data integrity, data security, immunity to interference and larger maximum length. They also offer additional interesting benefits compared to copper- based solutions, such as high quality electrical isolation between the individual components, low cable weight per meter, no electromagnetic radiation, laying directly next to high-energy cables and the immunity of the bit error rate to any type of electromagnetic disturbance. Operation of a fibre-optic line thus requires no additional measures with regard to...

In order to prevent damage to fibre-optic cables, whether immediately or during use, great care should be taken when laying them. The VDE laying regulations always apply. In addition, further specifications for indoor and outdoor laying according to DIN VDE 0899 Part 3 must be observed. Fibre-optic cable connectors In day-to-day industrial applications, four different types of connector are mainly used. These are SC, (V)ST, FSMA and MTRJ connectors. Other types of connector, such as ESCON, MIC, Mini-BNC, FC/PV, LC or Volition have to date been used on a very small scale. The connector used...

Ethernet components need power: The elimination of local power supplies by use of Power over Ethernet (PoE) can provide significantcost savings with systems such as VoiP, Web-Cams, embeded PCs, IP sensors, local automation and security systems.
