Hello @pavel_nadr,
we have released a new version of MervisIDE, which fixes the problem. Please, follow the information in this news: https://kb.unipi.technology/en:00-start?redirect=1#new_mervis_ide_os_v240_released

Hello @HPC,
since Modbus doesn't know anything about data types, it is up to both the master and slave to come up with an exchange format. The registers are 16bit, but the ASCII is only 8bit. The data has to be aligned somehow, or maybe two consecutive characters can be stored into one register?
Either way, the goal will be to iterate through the string and convert every item of the string array to byte.

Best regards,
Martin

Hello,

I just followed what you told me yesterday, but that doesn't change anything. In my .csv file, the values ​​that I save its data every second and not every tenth of a second ...
For the use that I make of it, it is absolutely necessary that I can obtain more values ​​per second.

As of now yes @lyngaas, until this gets fixed. Or you can create a function which does the recalculation properly.

Best regards,
Martin

@Martin-Kudláček Thank you.

Dobrý den @Jan-Toth,
toto bohužel není možné. Grafy v HMI pouze vzorkují hodnotu proměnné v čase a zobrazují dle nastavení poslední časový úsek.

S pozdravem,
Martin Kudláček

Hello @Mathurin,
I'm using the said SD card (without the HC) extensively and haven't encouter such behaviour, yet. Please, archive the whole Mervis project folder and send it to support@unipi.technology. I'll try to replicate the issue here.
Also include the version of IDE you are using and the version of MervisOS image.

Thank you and have a nice day,
Martin

Hello @kostastifki,
we have experienced such behaviour with Avast antivirus, blocking access to the Mervis project files. Try adding and exception for the MervisIDE.

Best regards,
Martin Kudlacek

Problem with activation solved. I have been using virtualised Windows 7 for Mervis programming (and activation) without any trouble until Mervis 2.4 and it seems there is some problem with SSL with current Mervis version and this outdated OS. Everything else works fine, only the activation process fails. With Windows 10 I was able to finish activation as usual.

But there is still problem with MervisDB and Proxy communication. SslHanshakeError persists.

@Martin-Kudláček said in How to delete variables and data on Mervis DB?:

...this is currently possible only from our support...

Thank you Martin, I may contact the support at one point, but for now, it is not an issue. It is more a cosmetic thing...

Best regards,
Lionel

Hello @larryvaredo, no, the MervisIDE is only a Windows application.

Best regards,
Martin

Dobrý den.
Děkuji za radu .Přejmenoval sem a nechal restartovat počítač .Po restartu mi Avast ještě blokoval přepis .
Už mi vše funguje.

:D

Oh yeah. I missed that part 🙈:

you need to upload the module's configuration "Configure Unipi Module". See more about it here: https://kb.unipi.technology/en:sw:01-mervis:unipi-configure-module-hidden

Thanks for your help! :-)

Hello @johni2212,
which version of MervisIDE and which version of MervisOS image do you use?

Thanks,
Martin

Dobrý den @ogast,
toto je současné omezení Mervisu. Pole nelze použít v FBD programech ani v HMI. Toto je možné obejít pomocí speciálních proměnných a mapování "tam a zpět". Tedy mít programy:

array_to_hmi
program1
program2
hmi_to_array

V array_to_hmi mít:

hmi_jedna := pole[1];
hmi_dva := pole[2];

A v hmi_to_array mít opačnou logiku:

pole[1] := hmi_jedna;
pole[2] := hmi_dva;

Programy program1 a program2 mohou být FBD a pracovat s proměnnými hmi_*.

Hello @msoenen,
please send the project alongside with the version of the MervisIDE you are using to support@unipi.technology.

Thank you,
Martin
