It's working, thanks!

Pro využití všech předností Mervis SCADA je nutné mít PLC připojené na Proxy a nastavené posílání dat do DB. Pokud máte takto PLC, které řídí FVE, již nakonfigurováno, nemusíte do programu vůbec šahat a stačí "pro jistotu" zkopírovat složku projektu a následně otevřít zkopírovaný projekt v Mervis IDE (min. verze 2.3.0) a postupovat dle návodu https://kb.unipi.technology/cs:sw:01-mervis:mervis-scada-project-hidden

Samozřejmě je možné pro SCADA využít i další PLC, které bude fungovat jako prostředník. Ideálně využít interní protokol SSCP po IP, který vám ušetří práci s vytvářením a udržováním Modbus tabulky. Výhoda je, že opravdu nemusíte zasahovat do původního projektu. Návod máme bohužel jen na verzi, kdy jsou obě PLC v jednom projektu viz https://kb.unipi.technology/cs:sw:01-mervis:multiple-unipi-through-sscp-hidden Ale stejně tak je možné vytvořit úplně nový projekt, přiřadit PLC a přidat nový Zdroj dat (pravé kliknutí na položku Systém v Solutuion Exploreru), vybrat zdrojový soubor projektu z prvního PLC (ve složce /bin) a nastavit parametry připojení.

Hey again,

I could solve the problem. I should have read the docs in more detail:
"The register expects values in range of 0 – 4000 which equals the range of 0 – 10 V." 👌
Sorry for spamming the forum here...

Solved by: The pre K value was set to 0.1 as described in the documentation. I set it back to 1. With one every measurement is working properly.

Question: Could you explain in more detail how the pre and post K and Q values are working. I'm a bit confused. Obviously its just a matter of scaling since for Pt1000 the pre K factor need to be set to 0.1. So for Pt500 the pre K factor should be set to 0.5? Am I correct?

Hi @martin_triska,

Yes, that sums up the situation well, so I'll write to support@unipi.technology for replacement request.

Many thanks,

Pascal

For the record - @r3sist discovered that the corrupted SD card has been causing the delays. Everything in the program has been configured correctly.

Hello @clueless,
the 1-Wire addresses are uploaded to the PLC with Deploy od the solution.

Update: I have install it in the fusebox now and there is diffrent powersource. And now it is just Run 3 blinking. And cant get the modul 3 to work.
Before works all of them after a reboot but stops and blinks after like 5 min.

The controller was not selected. It's working now. Thank you for pointing that out.

Here's what I'm using in my .gitignore:

*.bin bin *.exs *.zip */HmiResources */HMI-*

@OlivierP Thanks for the feedback!

Hi @OlivierP ,
you can change the byte order via MultiByte Order:

Hello @Neuron_Flo,
we tried different approaches, but non of them gave the correct result. There doesn't seem to be a native way how to transform this data in ST code. It looks like you need to resort to the classic calculation according to: https://en.wikipedia.org/wiki/Single-precision_floating-point_format

Hi @CKB,
the functionality has changed, and now you cannot define more than one task. But you can define more programs to run inside a single task.

Best regards,
Martin

Problem solved, I did a complete reinstallation in version 2.2, because version 2.3 does not work for me

thanks

Hello,

first, you do not need to worry about the unmapped variable.

Do you mean this tutorial https://kb.unipi.technology/en:sw:01-mervis:creating-new-project-hidden#connecting_the_inputs_outputs ? That should to date to the current Mervis IDE 2.3.0.

Could you share the whole zipped project folder?
