Convergence data limits for office/automation networks Not every Ethernet-based network can be planned, implemented and operated in the same way, and an inappropriate approach to achieving complete network convergence can be very costly for customers. But now, special network designs geared towards applications requirements are finding their way into industry. A WELL-THOUGHT-OUT CONNECTION between a organization’s office/data center and automation networks is a major challenge, especially in view of the tasks involved with the digitalization of industry and the comprehensive networking of all corporate areas and the extensive exchange of data. Since more and more companies today rely on Ethernet-based communication in industrial networks, special network designs geared towards the requirements of the applications have found their way into various industry sectors. Many IT departments are attempting to implement the connection required for the production networks using well-known procedures for the design and operation of office networks, break up existing Factory hall 2 Industrial Ethernet (Fiber Optic) - 1 Gbps industrial network structures, and integrate the automation devices into the existing IT infrastructure. However, this entails substantial risks for the companies. First of all, it should be noted that experienced providers consider the industrial network to be an integral part of the automation, and choose an entirely different approach to tackling greenfield and brownfield projects as compared to the planning of office and data center networks. The goal is to combine functional data exchange with failsafe automation. Structural/technical characteristics Industrial network infrastructure differs depending on the specific requirements of the Industrial Ethernet (Fiber Optic) - 1 Gbps individual industry sector and the needs of an individual company. In manufacturing companies, for example, the relevant areas of the industrial network part, depending on the network structure, range from the cell level and machine level (also called the access level) to the distribution level with the cell aggregations (including the shop floor aggregation, hall or station aggregation), and the connection of a possible industrial data center to the backbone aggregation. The latter, in turn, must be connected to the core area of the corporate network comprising the data center network structure via suitable interfaces and taking the security policy into consideration.
