PROFIBUS systems are especially made for process automation (PA). PROFIBUS is standardised acc. to IEC 61158 that means best interoperability of components from different manufacturers. The modular peripheral construction (DP: decentralised periphery) of the bus system simplifies installation and maintenance. The PROFIBUS type A is generally used in current systems, cables of PROFIBUS type B are only used for replacement purpose in already existing systems.Fast Connect cable constructionThese cables mostly have a radial symmetric construction. This enables the use of special stripping tools that make possible a quicker and easier harnessing and installation.
