A Complete Comparison: PROFINET RT vs IRT

In the PROFINET world, PROFINET Real Time (RT) and PROFINET Isochronous Real Time (IRT) are common terms. PROFINET RT and IRT can be employed to deliver data within a PROFINET network. PROFINET RT is equipped in all PROFINET components and fulfills the majority of industrial automation timing requirements. PROFINET IRT is optional as it is…

Can PROFINET and Ethernet Employ the Same Switch?

Switches are crucial components in industrial networks. They are commonly implemented in PROFINET configurations to deploy various topology options (i.e., tree, star, line, ring). But are those switches able to handle PROFINET telegrams and other Ethernet traffic? PROFINET can coexist with other Ethernet-based protocols in the same network and share network infrastructure, such as switches…

The Difference Between Ethernet and Industrial Ethernet

The terms Ethernet and Industrial Ethernet often create confusion as they are often used interchangeably. This post makes a comparison between Ethernet and Industrial Ethernet. Ethernet and Industrial Ethernet are the same thing. The only difference is that Industrial Ethernet includes running Ethernet traffic over more ruggedized hardware. For example, the cabling employed for Ethernet-based…

PROFINET Network Overview

When building an industrial network with PROFINET, you will employ three major pieces of hardware: controllers, devices, and general infrastructure. Controllers can be PLCs, DCSs, or PACs. Devices can be I/O blocks, RFID readers, drives, process instruments, proxies, or even other controllers. And cables, connectors, switches, and other components make up the network infrastructure. You…

What is PROFINET? – PROFINET Explained

This article answers a very general but common question: What is PROFINET? PROFINET is an open Industrial Ethernet solution based on international standards. It is a communication protocol designed to exchange data between controllers and devices in an automation setting. It was introduced in the early 2000s and is the most well-adopted Industrial Ethernet solution….

Is PROFIBUS Based on Ethernet?

Industrial communication protocols, such as PROFIBUS and PROFINET, are based on different physical layers. PROFIBUS is based on RS-485, which is a common serial communication method. PROFIBUS networks can achieve speeds of up to 12 Mbit/s, though most networks run at 1.5 Mbit/s. The telegram size can be up to 244 bytes, and the address…

How to Configure a PROFINET Network (Full Demonstration)

This video will show you how to configure a PROFINET network. PROFINET controllers have an associated engineering tool to configure the network. Even though engineering tools vary across manufacturers, there is a standard process for configuration. First, import the GSD file and configure the network in the Engineering Tool. Second, configure the devices and download…

The Difference Between PROFINET and PROFIsafe

PROFINET and PROFIsafe have very similar names and were both created by PROFIBUS and PROFINET International (PI). Besides the similarities in origin and name, PROFINET and PROFIsafe are different technologies. PROFINET is an open industrial Ethernet standard that offers real-time data exchange while maintaining openness for flexible plant and machine concepts. Aside from the standard…

What Is the Difference Between PROFIBUS DP and PA?

There are two flavors of PROFIBUS: PROFIBUS Decentralized Peripherals (DP) and Process Automation (PA). Each type targets different applications. PROFIBUS PA is used in process automation. The physical layer of PROFIBUS PA is Manchester Encoded Bus Powered (MBP), and the physical layer for PROFIBUS DP is RS-485. Even though a different physical layer is employed,…
