PROFINET – The Solution Platform for Process Automation

Filed under

Industrial communication is one of the key technologies for modern automation. It provides control and monitoring of machines and manufacturing and productions processes, the connection of insular solutions, and the linking of neighbor areas such as logistics, quality assurance, and maintenance and to higher-level company systems. 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 – even over great distances – are needed to make use of the many possibilities of the digital world.

This white paper reports which functions and capabilities of PROFINET are currently meeting the demands of process automation and which can be implemented and then used in products in the future, based on specifications that are complete or in progress.

PROFINET of Things

Filed under

PROFINET is foundational to the Industrial Internet of Things (IIoT) which lies in the overlap of the Internet of Things (IoT) and Industrie 4.0. There are differences between IoT and IIoT. This paper will extend that into the PROFINET of Things. Not just any Industrial Ethernet can claim to be foundational to IIoT; here are the benefits of PROFINET that differentiate it from the others – all in the context of IIoT.

PROFIBUS for Process Reprint

Filed under

Whether or not a new path is better is often decided only after it has been tread. Without new paths, however, there is no progress. This principle applies especially nowadays to the field of automation engineering, particularly in light of the much discussed innovative activities related to the terms “Cyber Physical Systems”, “Internet of Things”, and “Industry 4.0”. In spite of the hype surrounding these terms, there are in fact very concrete objectives out there whose purpose is to increase the efficiency, speed, flexibility, and safety of the process industry.

This magazine reprint provides 20 pages of benefits of using PROFIBUS with links to relevant videos.

PROFINET versus EtherNet/IP

Filed under

PI North America has often been called upon to compare PROFINET and EtherNet/IP. This white paper answers that call.

Disclaimer: we are not experts at EtherNet/IP, but we've researched publicly available information. Consider this document our opinion of the differences.

IT Professional’s Guide to Industrial Ethernet

Filed under

What are the five critical things an IT professional needs to know about bringing Ethernet to the plant floor?

It's important that IT professionals and automation engineers work together to create a robust, secure Ethernet infrastructure for the factory. This white paper can help.

6 PROFINET Myths – and the much better realities

Filed under

As more factory automation and process control applications advance from serial fieldbus communications to Ethernet based communications, there is confusion about the truths associated with Industrial Ethernet. Industrial Ethernet is not just one thing; it actually comes in more than one ‘flavor’, or protocol. Oftentimes, the lack of transparency surrounding one Industrial Ethernet protocol bleeds over into the information regarding another. Read this White Paper to find out what is myth and what is reality.

Ethernet Switches: Managed vs. Unmanaged for PROFINET

Filed under

Nearly all PROFINET devices have two ports on them, and behind these two ports is a switch. This makes it easy to create a Line topology. But there are often instances, where a Star topology would be a more efficient solution. To accomplish this, an external dedicated switch is required.

6 Reasons to Give PROFIBUS PA Another Look

Filed under

With over 8 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.

The 7 Step Industrial Ethernet Checklist

Filed under

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.

PROFINET for network geeks (and those who want to be)

Filed under

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.

Six PROFINET Highlights

This brief white paper highlights six of PROFINET's benefits: diagnostics, energy management, performance, security, wireless, and safety.

Time to migrate to Industrial Ethernet

Filed under

Users of industrial Ethernet in general and PROFINET in particular can realize greater productivity in several ways. One is by way of more flexibility, using wireless PLCs and mixing topologies, to tailor plant layouts for optimal output instead of having to adapt output to plant layouts. Another is greater efficiency, thanks to standardized cabling and plug-and-play parts and energy savings. The third is improved overall performance, given faster transmission speeds, much larger data packets, and greater precision control.

Profibus and Modbus: a comparison

Filed under

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.

Guide to Implementing PROFIBUS PA Field Devices

Filed under

This White Paper discusses the individual hardware and software aspects of implementing a PROFIBUS PA field device. This goal can be reached by following implementation approaches based on using pre-engineered hardware and software components.

Four-Pair PROFINET Cabling

Filed under

Today, Industrial Ethernet is being very successfully used in the automation environment to establish communication between devices. Four-pair PROFINET cables can address more demanding plant and system concepts and provide a technology that is fit for the future.
