PROFINET Application Profiles: PROFIsafe, PROFIenergy, PROFIdrive

PROFIBUS and PROFINET International (PI) has specified over a dozen PROFINET Application Profiles. Application Profiles are an additional layer above the PROFINET protocol. A PROFINET product that supports one or multiple Application Profiles offers further functionality besides the standard PROFINET capabilities. The most commonly implemented Application Profiles are PROFIsafe for functional safety, PROFIenergy for energy management, and PROFIdrive for interoperable drive devices.

PROFINET Redundancy: It’s all about UPtime

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.

PROFINET Cabling: Overview and Implementation Considerations

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.

Cableado Profinet: Visión General y Consideraciones para Implementación

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 vs PROFINET: Comparison and Migration Strategies

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 vs PROFINET: Comparación y Estrategias de Migración

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.
