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.
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.
Have you heard of the seven-layer stack used to define network functionality? It collapses to four layers in the Ethernet world… and PROFINET does not need all four of those. This illustrated white paper provides insight into the layers and how they are used.
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.
