PROFINET vs Ethernet: Definitions and a Comparison

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 by…

PROFINET Conformance Classes

All PROFINET products are developed according to international standards and certified by PROFIBUS and PROFINET International (PI). Every PROFINET device has a defined set of features that are mandatory based on its conformance class. There are three PROFINET conformance classes: A, B, and C. Conformance Class A (CC-A) is the most basic, while C (CC-C)…

Dynamic Reconfiguration

The process industries have many challenging production requirements. For example, in some applications, systems must run continuously without interruptions; not even emergency stops are possible. For those scenarios, PROFIBUS and PROFINET International (PI) specified a PROFINET feature to ensure continuous processes. Such feature is Dynamic Reconfiguration (DR). DR allows users to reconfigure, insert, remove, or…

PROFIsafe over Wireless

Nowadays, functional safety can be implemented over the bus shifting from safety in hard-wired relays to safety performed in logic. PROFIsafe is an additional software layer that provides functional safety over the bus in PROFINET networks. PROFIsafe ensures the integrity of failsafe signals transmitted between safety devices and a safety controller meeting the relevant safety…

PROFINET I-Device

I-Device is an optional PROFINET feature, which operates on the controller level. This feature allows a controller to be both a device and controller simultaneously, allowing for controller to controller (some might say peer to peer) communications with PROFINET.  I-Device functionality brings many benefits. For example, it enables the setup of communications between IO controllers…

Industrial Wireless Access Points

PROFINET supports WLAN and Bluetooth as part of its specification. PROFINET enables wireless connections without limitations*, even with safety messages (PROFIsafe). Since PROFINET is based on standard Ethernet, it does not require specialized networking hardware. Commercial off-the-shelf Wireless Access Points (WAPs) can be part of a PROFINET network. Even though specialized industrial WAPs are not…
