PROFINET Installation Considerations

It is crucial to start a PROFINET project by reading the installation guidelines. The PROFINET guidelines help ensure your networks are stable and efficient. This year, some blogposts(like this one) will cover installation topics. Here are some tips and best practices for your PROFINET installation: Routing PROFINET Cables PROFINET Cabling should be routed appropriately and…

Scalable PROFINET System Redundancy

Redundancy is a requirement in many process automation systems.  Four PROFINET system redundancy configurations have been defined by PROFIBUS & PROFINET International: S1, S2, R1, and R2. First, S or R denotes whether a PROFINET node implements either a Single or a set of Redundant Network Access Point (NAP).  Then, the number following S or R determines the number…

PROFINET Redundant Components

Generally, in an automation network, there are many components that can potentially fail. Depending on the end user’s requirement, PROFINET allows them to build a reliable network according to their specific goals. Specifically, there are four PROFINET redundant components: Media Redundancy, Controller Redundancy, Device Redundancy, and Network Redundancy. Device Redundancy A network with device redundancy has a…

Switches and Ring Topologies

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. Some topologies permit redundant media and decrease the chance of failure. Specifically, PROFINET allows you to…

Bringing Ethernet to the Plant Floor

Bringing Ethernet to the Plant Floor? Seven critical things to know before you do it. 1.  Do not to take Office topologies to the plant floor but implement plant/machine topologies with Ethernet. Office Ethernet infrastructures are typically based on commercial grade products meant to be located in a temperature controlled environment and Ethernet switches designed…

Six Profinet Highlights

Profinet provides one network for all applications: factory automation, process automation, and motion control. Although, there are many benefits to using Profinet, let’s focus on six of them: Diagnostics During commissioning, maintenance, or when an error occurs, it is necessary to obtain an overview of the plant or machine status in minimum time. The integrated…

Diagnostics and PROFINET Webinar- Q&A

A few weeks ago we hosted a webinar together with the PIC (PROFI-Interface Center) about PROFINET Diagnostics. We had many attendees and several of them had very interesting questions during the webinar. As a recap and a way to sum up most of the questions, we have answered them below. Q&A 1.-Is there a generic…

PROFINET Proxies and Gateways

Migrating from a Fieldbus or other industrial Ethernet to PROFINET is a common challenge. Every automation system is specialized in some way, and specialized components may not “speak” PROFINET. To move data from the specialized systems up to the PROFINET network, you have to add an interpreter to the network: A Proxy or a Gateway.…
