Abstracts from The Smart Way to Industry 4 with PROFINET Seminars


Ethernet’s copper physical layer finally unveiled
Frederic Depuydt, KU Leuven (Catholic University of Leuven, Belgium)

The components and basic properties of the 100BASE-TX physical layer for industrial wired ethernet, the “invisible” signal coding (4B/5B, scrambling, MLT3), the actual voltage signals on the copper wires, and some signal and packet measurement methods are discussed. Actual measurements in PROFINET networks illustrate signal properties, bits, bytes and messages.

Redundancy for PROFINET networks
Frederic Depuydt & Philippe Saey, KU Leuven (Catholic University of Leuven, Belgium)

When communication fails, PROFINET IO Devices go to their failsafe state. For more critical networks one could consider creating redundant paths in the PROFINET network. The working principle of industrially available redundant Ethernet technologies such as MRP, PRP and HSR is explained, measurements and some industrial case studies are discussed.

Industrial control cases with MATLAB code in PLCs, using PROFINET’s “oversampling” & “I-Device” features
Philippe Saey, KU Leuven (Catholic University of Leuven, Belgium)

PLCs running code generated from MATLAB/Simulink has recently been promoted heavily on the Hannover Messe and SPS Drives. What is this? How do we use the quite unknown oversampling and I-Device features of PROFINET to even extend the application range? Some basics and use cases from industry to inspire you!

Combining data and power: Power-over-ethernet and Power Line Communication
Jos Knockaert, UGent (Ghent University, Belgium)

Smart technologies need both power and communication. Is combining power and data in one cable a feasible and robust solution for your application? In this lecture, the basic ideas, needed technology and standardisation are explained.

EMC and HFPQ for industrial networks
Jos Knockaert, UGent (Ghent University, Belgium)

The basis for intelligent automation is communication. The increasing use of communication makes industry increasingly vulnerable to interference. This EMC lecture gives an insight into the disturbance mechanism based on real industrial cases and provides you solutions.
