  • APL: cómo llevar Ethernet a zonas peligrosas

    “La materialización de esta visión comenzó en 2011, cuando un grupo de proveedores de soluciones, a petición de varios grupos de usuarios finales, comenzaron una investigación técnica de una capa física avanzada independiente de protocolo (conocida como APL) que dará la posibilidad de utilizar Ethernet en lugares peligrosos (seguridad intrínseca)”. Documento técnico de APL Decripción Para…

  • PROFIdrive for Interoperable Drive Devices

    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 PROFINET Application Profiles are PROFIsafe for functional safety, PROFIenergy for…

  • PROFINET IRT- Isochronous Real Time

    PROFINET employs its first two communication channels: TCP/IP and UDP/IP, and Real-Time (RT) for most data exchange. It employs TCP/IP (or UDP/IP) communications for non-time-critical tasks, such as configuration, diagnostics, and parameterization. And PROFINET RT handles time-critical data exchange. Yet, some industrial applications require faster performance. For those applications, PROFINET employs the Isochronous Real-Time (IRT)…

  • PROFINET RT: Real-Time Performance

    Every industrial network has a unique set of requirements as it must fulfill a variety of different tasks. Some tasks require high-speed synchronized communication. Others are not as time-critical. PROFINET is the world’s most advanced Industrial Ethernet solution. It is a communication protocol to exchange data between controllers and devices. PROFINET can operate in challenging…

  • PROFINET Optional Features

    All PROFINET products are developed according to international standards and certified by PROFIBUS and PROFINET International (PI). Aside from the mandatory characteristics in each PROFINET device, PI defines a list of optional features. The next section covers a brief definition of several PROFINET optional features. The list below is not comprehensive, but it includes the…

  • The Difference between PROFIBUS and PROFINET

    What is the difference between PROFIBUS and PROFINET? We get this question fairly often. This article covers a comparison between PROFIBUS and PROFINET. In short: PROFIBUS is a classic serial Fieldbus, and PROFINET is an industrial Ethernet protocol. PROFIBUS and PROFINET are both IEC standards created by the same organization: PROFIBUS and PROFINET International. Because…

  • PROFINET Profiles, Additional Layers of Functionality

    PROFIBUS and PROFINET International (PI) working groups develop Application profiles to ensure the openness, interoperability, and interchangeability of devices. PROFINET Application Profiles are vendor-independent specifications. They are implemented into PROFINET devices to enable the uniform behavior of devices from different manufacturers. These Application Profiles relate to device families or unique industry sector solutions. Application Profiles…

  • PROFINET Redundancy: Device, Controller, Network, and Media

    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. PROFINET allows you to build a reliable network according to your specific requirements. Specifically, PROFINET offers four redundancy options: Device Redundancy, Controller Redundancy, Network Redundancy, and Media Redundancy. Device Redundancy…

  • PROFIsafe: Functional Safety Over the Bus

    Functional safety (fail-safe) is the overall part of safety which aims to prevent hazards due to the incorrect functioning of industrial machinery. Traditionally, functional safety systems relied on separately wired circuits that are expensive to build, commission, and maintain. Nowadays, functional safety can be done over the fieldbus, shifting from safety in hard relays to…
