Network topology is a term that describes network connections in homes, cities, offices, factories, etc. Fieldbuses and Industrial Ethernet protocols, such as PROFIBUS and PROFINET, offer a wide variety of topology options. This White Paper describes the different network topologies available for industrial environments. Then, it summarizes potential benefits and challenges for each topology in a PROFINET network.
Are you ready to add PROFINET to your automation device? There are many choices of ways to add PROFINET to an automation device that it can seem daunting to know where to start. The starting point depends on the type of product, its existing design, quantity expected, and time to market needed. This brochure will explain the process and help you select a partner to expedite it: "The Easy Way to PROFINET - North American Edition".
Automation networks have always been designed to meet two key criteria: reliability and availability. Reliability is the first priority. Data that enters the network should be unchanged and always make it to its destination. Availability is a more complex problem because it’s not just about moving bits across a network. Redundancy mechanisms turn a reliable system into a highly available system, adding extra components or functionality to maintain reliable operation through a number of failures. This White Paper goes over the four components of a PROFINET redundant network. Then, it covers PROFINET’s scalable system redundancy configurations.
Even though wireless access points are becoming more popular, most of today’s network connections are wired and require cabling. PROFINET cable manufacturers offer a range of cable types and classes for different applications, including those with special properties. These cables come in two flavors: copper and fiber optics. This paper will give an overview of each, use cases, and implementation. Topics include copper cables, fiber cables, special features, and installation considerations.
Las redes PROFINET están construidas en base al estándar Ethernet IEEE 802.3. Aun cuando los puntos de acceso inalámbricos están ganando popularidad, la mayor parte de las conexiones de red actuales usan cables de cobre y requieren del correspondiente cableado. Los fabricantes de cable PROFINET ofrecen un amplio rango de tipos y clases de cables adecuados para diferentes aplicaciones, incluyendo aquellas que requieren propiedades especiales. Estos cables están disponibles en dos clases: cobre y fibras ópticas. Este documento presenta una visión general de ambas clases, su uso adecuado y su implementación.
PROFIBUS is a classical serial fieldbus and PROFINET is an industrial Ethernet standard. They share similarities due to their common source, but PROFINET has additional capabilities that allow faster and more flexible communication. This white paper will explore the differences between them and explain migration strategies from PROFIBUS to PROFINET.
PROFIBUS y PROFINET son dos diferentes protocolos de comunicación para uso en automatización industrial ampliamente implementados y desarrollados por la misma organización, PI (PROFIBUS & PROFINET International). PROFIBUS es un bus de campo en serie clásico basado en RS-485 y PROFINET es un estándar de Ethernet industrial. Comparten similitudes debido a su origen común, pero PROFINET tiene capacidades adicionales que le permiten ofrecer una comunicación más rápida y más flexible. Este documento técnico explorará las diferencias entre ellos y explicará las estrategias de migración de PROFIBUS a PROFINET.
Industrial communication is one of the key technologies for modern automation. In Industrie 4.0, Industrial Internet of Things, and Big Data environments, industrial communication is of central importance. Easy-to-handle solutions with high-performance capability for real-time communications, high availability, flexible topologies, and integration are needed to make use of the many possibilities of the digital world. This white paper reports the functions and capabilities of PROFINET that meet the demands of process automation.
What are the five critical things an IT professional needs to know about bringing Ethernet to the plant floor? First, it is important that IT professionals and automation engineers work together to create a robust, secure Ethernet infrastructure for the factory. Read this White Paper for insight into issues IT professionals should consider as they connect Industrial Ethernet-like PROFINET to the plant floor.
PROFINET offers a variety of possible topologies: tree, line, ring, star, etc. Nearly all PROFINET devices have two ports on them, and behind these two ports, there is an integrated switch which allows the creation of a line topology. Star topologies may be more efficient solutions in some cases and for that, you have dedicated Ethernet switches. Switches come in two broad flavors: managed and unmanaged. Even though you may be able to use both in a PROFINET network, they are very different...
