Age: 27 days12 years ago a small group of researchers presented the first public version of Eclipse 4diac at the 2007 IEEE Conference on Industrial Informatics in Vienna. Our baby made major steps in its early life, now just passing grade school and already helping a lot of people out there.

We would like to draw your attention to a funding opportunity for experiments around Eclipse 4diac.
The European network MIDIH supports selected application and technology experiments around Big Data with a reference architecture based on a stack of proven technologies (including Eclipse 4diac) with up to 60 000 € funding. Individual applicants can - once again - submit applications until 06.08. Topics can, for example be, additive manufacturing, inter- and intralogistics, modelling/simulation, VR/AR and AI/ML.
Further information is available at https://midih.eu/opencall_2.php

Age: 51 daysHere is a new update on my GSoC project. We have now finished the first phase and i already started to fix the first bugs. Deploying FBs with very basic functionality should now work again from the development branch. The next step is to find the causes, why certain functionality is not working properly. Therefore, i created a new list of bugs as roadmap we are going to do. You can find more detailed information in the eclipse wiki

Our powered by 4diac traffic light demonstrator reached Gothenburg to take part in the workshop of the Productive 4.0 project. The 4diac application can now communicate with the Arrowhead Framework over HTTP REST and/or OPC UA.
The documentation about how to use this amazing library in 4diac can be found here. You can easily register your own services and look for orchestration rules for your devices.

Age: 69 daysMy first two weeks of GSoC are now over and i have my first results to share with you. If there are any questions, as always, feel free to ask over Mattermost or the mailing list.
I just finished the first test phase of the dynamic type loader. To summarize, simple Basic FBs can already deployed without any troubles, e.g., calculations, FOR loops and Conditions (i.e., IF, CASE). In addition, all types of ECCs i found and internal variables also work. Datatypes seem to be working too, except Time Types. There is an open bug for this already. For functions, there is an open bug too.
I newly discovered, that some of the simple Structured Text functionality is still not supported, like WHILE/REPEAT loops or standard functions.

Age: 80 daysOver the last months we where working to give the 4diac logo and icons a new more polished look. This has come to an end and we are happy to present the new logo and icon suite:
I hope you like the new logos. With this post we already updated the 4diac web-page to the new design.

It is a great pleasure for me that this year we got a student project sponsored in the Google Summer of Code. Jan Holzweber will work on our Lua-based dynamic code loading infrastructure and turn it from experimental prototype into a usable stable feature.
Please give Jan a warm welcome and your support.
I’m looking forward to work as mentor with him.

Age: 127 daysWe are proud to announce the second maintenance release for 4DIAC 1.10 providing 11 bug fixes for 4diac IDE, and 6 for 4diac FORTE.
As always please download, test, and report problems and bugs.
For 1.9.x and 1.10.x users a simple Help -> Check of Updates
should upgrade you to 1.10.2.

fortiss showed two 4diac-based demonstrators at the Inspire Automation Camp from 25th to 27th February organized by Festo in Esslingen.
A Pick-and-Place module demonstrates the skill-based approach for an automation system using OPC UA. The module consists of a vertical axis, a horizontal axis, a gripper and a conveyor belt that are controlled by a Festo CECC-D, an emBrick, a Kunbus RevolutionPi and an INSYS MRX3 respectively. This engineering approach hides the implementation complexity on the target system by providing a standardized interface to the process via skills. The gripper, for example, is controlled by a skill gripper that can be called via OPC UA.
The second demonstrator shows 4diac's TSN capabilities by sending two streams, a prioritized TSN stream and a non-prioritized best-effort stream, between two Beaglebone Black devices via 3 TTTech Akro 6/0 TSN switches. All devices have a common time base, which is achieved by the Precision Time Protocol (IEEE1588 - PTP). The prioritized stream is synchronized to a specific sending time point. The demonstrator shows on the one hand how 4diac uses the deterministic features of TSN, which means that the transmission of packets can be guaranteed and on the other hand that synchronizing the application and network schedule reduces latency and jitter of the transmitted packets.

Age: 209 daysThe European Innovation project FED4SAE is currently eliciting proposals for innovative industrial application development projects in the domain of Cyber-Physical Systems and Embedded Systems. FED4SAE is looking for companies that want to:
- Develop novel and innovative smart solutions to take a leading position in their target markets.
- Use the most advanced technologies and industrialized solutions to link the physical world with the virtual world in combining hardware and software expertise.
- Gain premium access to resources, competencies and reduce development time.
- Enter into a unique European ecosystem gathering leading industrial companies, world-class research organizations, innovation accelerators and private investors.
To do this, FED4SAE offers companies:
- Product support via industrial platforms – existing products provided by market leaders ( AVL, Intel, ST, and Thales ) – in the domain of cyber-physical and embedded systems that can bring the innovation to a state of maturity.
- Technical expertise via advanced platforms (e.g., Eclipse 4diac) by RTOs ( BME, CSEM, Digital Catapult, Fraunhofer IISB, fortiss, KTH, and Unican) – either innovative technical solutions or testbeds – which will add value to the product.
- Innovation management – focusing on business – to help your innovation get to the market via the FED4SAE and the Smart Anything Everywhere ecosystem.
- Up to €58,000 in funding – representing 70% of the declared budget in your proposal.

In our currently running usability survey a hotspot for disappointment is showing up, namely the application deployment. Interestingly we started on this already in the last release. With 4diac 1.10. the following improvements are available:
- No more connection refused error messages: 4diac IDE automatically deactivates monitoring if needed and after the deployment re-enables it.
- No more invalid state error messages: Deployment checks the running resources in a device and lets you overwrite them:
- Deploy from where you want:
With a new deploy main menu and pop-up menu you can select deployable entities (i.e., resources, devices, or full systems) and deploy them on the fly.
We hope that this makes deploying a less painful experience in 4diac IDE.
Outlook
However we know that this is only a first step. More work is needed to fully get rid of the deployment perspective as a whole.
Furthermore there is a major disturbing step in deployment that we haven’t talked about yet: FB type management. Every time you change an FB or create a new one, C++ code for the FB has to be created and 4diac FORTE needs to be recompiled.
In order to overcome this issue we added as experimental feature a dynamic type load option. Here 4diac IDE detects during deployment the availability of FB types and for missing types code is automatically generated and sent to 4diac FORTE. To enable this feature you need to compile 4diac FORTE with LUA enabled and change in the system configuration of your application the device profile to dynamic type load.
However bear in mind that this feature is still experimental. Nonetheless we need testers for it. So we are heavily looking for your feedback on it!
Your feedback really always helps and there are several ways to provide it:
- Submit issues and suggestions through our bug tracker
- Fill out our anonymous 4diac IDE UX questionnaire
- Participate in our usability assessment
Thanks in advance for your support,
The 4diac Team
