      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,

      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.

      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

      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?
