Industrial Wireless Architectures- PROFINET

PROFINET can be connected wirelessly as easily and seamlessly as it can be connected with regular wires (copper, fiber). Wireless is part of PROFINET’s specification for two wireless standards: Wi-Fi and Bluetooth. When speaking about wireless PROFINET communications for industrial automation, there are a variety of architectures available depending on the particular application. This post will go…

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…
