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...
Fieldbus systems have a proven track record that goes back to the early 1990’s, and PROFIBUS has been at the forefront. With over 50 million nodes installed, thousands of applications, and over a decade's worth of experience, users are installing PROFIBUS as the network of choice in the chemical, pharmaceutical, food processing, bio-gas, offshore oil production, and mining industries.
In today’s information-age, it should be easier than ever to make decisions based on the technical merit of an automation backbone, instead of following a particular vendor’s Industrial Ethernet protocol of choice.
With over 25 million installed nodes, PROFINET is one of the most widely used Industrial Ethernet standards worldwide. But even though millions of users are familiar with PROFINET, not all users understand how it works. This white paper describes PROFINET’s 3 communication channels: TCP/IP and UDP/IP, Real-Time, and Isochronous Real-Time.
We live in a multi-protocol world – and this will likely not change anytime soon. Different protocols work better in different applications. I have not come to bury Modbus or Profibus, nor to praise them, but rather to add some perspective and knowledge. An introduction is provided to each technology on the basic underpinnings. This is followed by application examples and finally a side-by-side comparison.
PROFINET and PROFIdrive form the basis for high-performance and future-proof drive technologies. Together they offer a comprehensive range of applications, scalable performance with short cycle times, and user-friendly, cost-effective implementation. In combination with PROFIdrive, PROFINET becomes is the ideal solution for all drive tasks.
Automation users worldwide are driven to minimize energy consumption, to cut costs and comply with increasingly stringent ‘green’ obligations. PROFIenergy offers a solution, enabling the deployment of smart energy management strategies over PROFINET. This white paper introduces the PROFIenergy Profile and gives an in-depth overview with use cases and implementation.
"University of Cologne AIT; PROFIenergy Study" details the study performed at an automotive plant of energy consumption. It presents real quantitative data and the significant potential savings of using PROFIenergy.
Profibus & PROFINET International has mated safety with industrial networking to create solutions for “networked safety” based on all available media. End-users are now taking advantage of PROFIsafe to unify their network architectures and eliminate the need for a second, parallel bus while maintaining conformity with safety standards up to SIL3. This white paper presents compelling benefits for using PROFIsafe and two success stories.
Process fieldbuses and open fieldbus safety protocols have caught the attention of process users in recent years thanks to the potential to cut costs and improve diagnostics. Separate the facts from the hype in this ARC white paper: Profisafe and Profibus for High Availability and Safety in the Process Industries.
