PROFINET vs Ethernet: Definitions and a Comparison

loading… What is the difference between PROFINET and Ethernet? Can you give us a PROFINET vs Ethernet comparison? We get these questions quite often. And they are kind of difficult to answer because PROFINET and Ethernet are complementing technologies, not competing technologies. This short post will illustrate the comparison between PROFINET and Ethernet. Let’s start…

PROFINET Switch Options and Features

loading… PROFINET offers a variety of possible topologies: tree, line, ring, star, etc. Nearly all PROFINET devices have at least two ports on them, and behind these two ports, there is an integrated switch that allows the creation of line topologies. Star topologies are efficient solutions in some applications, and for that, you have dedicated…

PROFINET IRT- Isochronous Real Time

loading… 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…
