OSADL Networking Week 2021

"OPC UA PubSub over TSN using open62541 and beyond"

Virtual, by live video streams and video conference
Session I - Monday, June 14, 2021 - 10am to 12pm CEST
Session II - Tuesday, June 15, 2021 - 2pm to 4pm CEST
Session III - Wednesday, June 16, 2021 - 10am to 12pm CEST

This year, the traditional face-to-face OSADL Networking Day in Heidelberg will be, once again, transformed into an online OSADL Networking Week with daily two-hour sessions over four consecutive days. The daily two-hour sessions will consist of live video stream presentations followed by a discussion via video conference, alternating in the morning and in the afternoon.

The OSADL Networking Week will take place from Monday, June 14 to Thursday, June 17, 2021. All OSADL regular, associate and academic members are cordially invited to attend the virtual OSADL Networking Week. We would be very pleased if, as in years before, the mix of specialist presentations on a current topic and the opportunity for discussion motivated many OSADL members to participate. In addition, non-member participants who are interested in OSADL and its work may also attend.

The topic of the OSADL Networking Week 2021 is "OPC UA PubSub over TSN using open62541 and beyond".


When a couple of years ago the decision was made to select OPC UA PubSub over TSN as the future worldwide standard for real-time communication it was clear that we will have a long way to go. And based on the 802.1 Qxx standardization schedule it was also relatively clear how this way would look like. However, it was less clear how the various software components could be realized and how their development would be funded. Pretty quickly, it became evident that the independence that such a worldwide universal protocol requires can only be achieved with an implementation by an Open Source community. One of these Open Source communities is the initially publicly funded open62541 project that was started a couple of years ago and is maintained, among others, by Fraunhofer IOSB. One of the important contributors to this project is the India-based company Kalycito Infotech. These two companies accepted to become operative partners in an OSADL managed and so-called mixed-funded project named "Building an Open Source OPC UA over TSN Ecosystem". This project has now reached the third phase, and the OSADL Networking Week 2021 is a welcome opportunity to present the various achievements of this project and to put it into a larger context.


The four sessions of the OSADL Networking Week on "OPC UA PubSub over TSN using open62541 and beyond" will take place virtually by live video streams. The discussion rounds at the end of each session will take place by video conference. Information how to access the live video streams and subsequent discussions will be sent to the registered participants prior to the event.
