@har Hi har,
Thanks for the additional info. We are not able to provide free support on this since it's your custom Python script. The error is not related to the Rexygen ecosystem. It seems that the CPU dispatcher is being initialised multiple times.
Tomas
@har Yes, the issue is in initialisation of the Python Block. If you wait a second with the mouse on the message 
it will show you more instead of "..." which might help you to find the issue easier.
Cheers,
Tomas
Hi har,
thanks for your question. Please, can you share System Log? There should be some error which is preventing RexCore from running.
Cheers, Tomas
Hi Phil,
Thanks for your question. Please, have a look at example "0305-01 Hour Meter" - it should do the job or point you in the right direction.
Let us know if it helped.
Cheers,
Tomas
Hi Phil,
Thanks for your question.
Yes, it is possible using AlarmsTable HMI component - see docs: https://www.rexygen.com/doc/ENGLISH/MANUALS/RexHMI/RexHMI_ENG.html#x1-180002.4.3
More about the REXYGEN Alarm feature can be found here: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/ALARMS.html#x8-70002
To create a banner, you can use the Dialog feature, which is part of the Group Animation settings.
Let me know if I can be of any assistance.
Cheers,
Tomas
@MikeyH Hi Mike,
Thanks for reporting this. This is really weird. Please, can you record and share your screen? E.g. using online tool https://gifcap.dev/
Kind regards,
Tomas
@MikeyH Hi Mike!
Do you use the same versions of Development tools and REXYGEN Runtime?
The TRND not providing any data seems to be disabled - is it active in the running project?
The error message about parsing the output can be omitted - the extension returns something which throws this error. It won't affect the behaviour of the HMI. We will try to fix it. Can you share your source files with us?
Kind regards,
Tomas
@bech Hi John,
There is the exec counter feature built into the REXYGEN diagnostics. And it is accessible via special signals. The example you are looking for is "0001 Special Signals", and the parameter is excnt.
Thanks for your comment. We are working on better interconnection between the Function block documentation and the Example library. For now, you can use search input within the Examples library to help you find the right example.
Let me know if it helped.
Kind Regards,
Tomas
@MikeyH Hi Mike,
The version you have is correct. The issue is in running the HMI Designer without proper initialization. Try to run the Designer via REXYGEN TrayMon (see the screenshot)
The thing is that you need to tell the Designer which REXYGEN version is valid. The reason for this is that one Designer version is shared among all REXYGEN versions, so you don't have to install all Designer things every time you install a new REXYGEN version. If you run Designer without this connection, it won't work. Running the Designer via TrayMon should solve this.
Kind regards,
Tomas
@MikeyH Hi Mike,
Yes, your assumption is right. Always try to have the same versions both on your PC and on your target device.
The update process depends on the state of your OS image. If you don't need any fixed version of other packages for some reason, I would perform an upgrade of the whole OS:
sudo apt update
sudo apt upgrade
If it won't help, you will probably need to change the location of the REXYGEN packages - for more details, see Chapter "Manual installation" in the documentation provided with the 3.0.3 Development tools.
Let me know if it helps.

Tomas
@carvin Hi carvin,
thanks for your feedback. I would suggest to use the SRTF function block with some certain subsystem (e.g. "sybsystem_slow") within your fast task.
Would that solve your issue?
Cheers,
Tomas
@stepan-ozana Hi Stepan,
Thank you for your question. It is possible to set the start of task execution as soon as the previous task ends. More details in TASK documentation: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/TASK.html#x26-250002
Information between tasks should be always sent via Inports and Outports if possible (SETPx function blocks can introduce undesired inverse of priorities when sending data between tasks).
Second part - "on demand" execution:
Thanks for sharing your solution! It is also possible to use SRTF function block (Set run-time flags):
Doc: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/SRTF.html#x21-200002
If you need any assistance just let me know.
Cheers,
Tomas
Hi Carvin,
Thanks for the question. With all the provided information I don't see anything suspicious. Please, can you share the whole project (mdl files at minimum) just to see all other information and configuration which are not visible from the screenshot?
Just be aware that arrays and vectors in REXYGEN are connected by references so the flow of "information" is different from ordinary "wire" flow where the wire starts somewhere and goes somewhere else. Contrary reference contains the same data in every instance.
Kind regards,
Tomas
@gninaus Hi Guenther,
the fix is available in our daily build repository: https://download.rexcontrols.cz/partner/daily/
Feel free to test it and report back.
Kind Regards,
Tomas
Hi Guenther,
Thank you for your bug report. Our developers fixed that immediately. The fix is now under test, and I will let you know once it is publicly available.
Thank you for your understanding.
Cheers,
Tomas
@Scoobsalamander Hi Kris, thanks for your question!
We are still missing the converter from EtherCAT XML files to our driver which is crucial for EtherCAT setup. Do you have any EtherCAT IO modules in your mind? We can prepare a basic example for you so you can modify it according to your needs. What do you think?
Please, note that the Raspberry Pi is not the best piece of HW for challenging tasks and short communication periods 
Cheers,
Tomas
@Tourneur Hi,
glad you made it work!
Yes, it is possible to make a custom component (separate SVG file). For more details see example "0301-12 HMI with External file".
Cheers,
Tomas
@Tourneur Hi! What a progress - great!
You just need to change the pivot point by means of the Inscape editor. Feel free to Google any Inkscape-related documentation on this (e.g. https://www.tutorviacomputer.com/inkscape/rotate-flip-objects/)
Note: Once the object is "animated" by REXYGEN Extension I recommend you to delete the object, change the pivot point and make the animation again.
Good luck!
Tomas
@stepan-ozana Thanks for sharing your solution with the community!
Good luck with your project.
Tomas
@Tourneur Hi! For the gauge sketched at the beginning of this topic you don't need any hand coding and the old forum post is overkill.
Just have a look at the example 0301-08 HMI Animation DEMO and read HMI documentation - Chapter 3.3.1 Group Animation: https://www.rexygen.com/doc/ENGLISH/MANUALS/RexHMI/RexHMI_ENG.html#x1-180003.3.1
Kind regards,
Tomas
