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.
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. These features are not required in all PROFINET devices; nonetheless, they can provide tremendous added value.
Wireless connections open up a wide variety of applications which are very difficult or impossible with regular cabling. PROFINET supports WLAN and Bluetooth as part of its specification. PROFINET enables wireless connections without limitations, even with safety messages (PROFIsafe).
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.
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.
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.
