The problem is caused by a large value in the parameters tn and tp. The change occurs, but it is very slow. For a faster transition between values, set lower parameter values. For an immediate change, set 0.

@stepan-ozana Hello,
thank you for your report.

Please, what version of REXYGEN are you using? I've tested it now on 3.0.4.17197 and everything seems to work. I'm attaching a printscreen and the project.

Hello Štěpán,

Thanks for the detailed summary — that’s really helpful!

Regarding the first experiment with the SETPS command:
The reason the CNSTEST1:scv parameter wasn’t updated is due to the SETF parameter of the SETPS block being set to "on". In this configuration, the value is only updated on a rising edge at the SET input.
To allow the value to be updated continuously, set SETF to "off". This way, the parameter will be updated in each cycle regardless of input transitions.

As for the issue with setting the CNA:filename parameter:
The filename specified here is not part of the application on the target device. Instead, the file resides on the host PC, and its contents are imported into the project during compilation.
That’s why the filename parameter cannot be changed online — it only serves as a reference for the compiler, not as a runtime variable.
Similarly, updating the nmax parameter isn't possible either, because REXYGEN does not support dynamic arrays — both the size and content of arrays are fixed during compilation.

As a general rule, parameters that can be modified online via SETP blocks are the same ones you can manually change in Watch mode — in other words, those that are not greyed out in the parameter list. If a parameter is greyed out, it means it’s read-only during runtime and cannot be changed programmatically either.

Cheers,
Jan

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.

Cheers,
Tomas

@stepan-ozana
Thanks, that looks great! I'll modify the schema a little more to match the conventions of the other blocks and include it in the installation.
