      Hi @r3sist,
      the:

      IF bPumpOn THEN hw.$Neuron M203_RO_2.06_w$:= TRUE; ELSE hw.$Neuron M203_RO_2.06_w$:= FALSE; END_IF;

      is exactly the same as this:

      hw.$Neuron M203_RO_2.06_w$:= bPumpOn;

      If there is no syntactic error, which would be detected upon MervisIDE Build, then there is error in the program itself. Try uploading it here or sending it to [email protected]. Please, include a VERY detailed description of the real process, not the itself program. It will help find the real issue.

      Hello @holzenbein,
      it is on the last row under section "task". The value is in seconds, otherwise it would mean the cycle time is e.g. 10 microseconds, which wouldn't be possible.

      Dobrý den @vladahos,
      Mervis je navržen pro průmyslové nasazení a podporuje tedy průmyslové komunikační sběrnice, zejména Modbus. Rozkomunikování s jinými zařízeními přes další protokoly vyžaduje značné úsilí. Nejčastěji pro naše potřeby používáme skripty napsané v Pythonu, které vyčítají/zapisují hodnoty do Mervisu přes ModbusTCP.

      Zde je několik odkazů, které budete pro daný úkol potřebovat:

      Hello @wzp,
      not exactly. You can check if the project is the same - start debugging and if the project on the PLC is different, you will be notified in the Output tab in the bottom panel.

      Zdravím @ondrejilichman,
      Mervis se bohužel na komunikaci s "internetem věcí" prakticky nehodí. Jeho doménou je lehký průmysl, kde má slušnou podporů protokolů. Komunikaci přes protokoly, které nepodporuje, řešíme u nás interně tak, že si napíšeme "bridge" v Pythonu, který s projektem v Mervisu zkomunikujeme přes ModbusTCP.

      Spíše bych Vám poradil se podívat na Node-RED, se kterým byste toho mohl dosáhnout výrazně jednodušeji. Jak na Node-RED na našich PLC se dozvíte zde: https://kb.unipi.technology/en:sw:03-3rd-party:nodered

      S pozdravem,
      Martin

      Hello @morax,
      the issue has been fixed with the release of MervisIDE 2.2.0. You have to use appropriate OS image as well: https://kb.unipi.technology/files:software:mervis:00-start

      I thought it might have been a lack of IP address in the TCP Modbus connector so did a rebuild.

      However, it started working before I changed it so perhaps the install did not complete correctly the first time around. Oh well, a somewhat frustrating amount of time wasted :)

      P

      Dear Unipi support team,

      Is there a way to make the SSCP to SQL Bridge more robust, for example, so that it is not necessary to restart it manually after every solution deployment or PLC restart?

      Many thanks in advance and kind regards.

      yes, now we have new CZ tutorial for SSCP comunication. With SSCP you can full control any variables, I/Os and modules of slave UniPi.

      Hi @pascal37,
      technically, in older IDEs it was possible to configure more tasks, but they behaved erradicaly. The communication stopped working randomly and so on. This problem is buried deep in the MervisRT and will take some time to fix. That's the reason, why since IDE 2.2.0 the multiple tasks are disabled.

      Thanks for understanding,
      Martin

      Dobrý den @airborne,
      to lze / je potřeba ošetřit přímo v programu. V jazyce ST je to jednoduché pomocí konstrukce IF. V jazyce FBD to lze provést pomocí bloků Integer a Boolean memory, kterými povolíte / zablokujete propisování hodnot z programu do výstupů. Záleží na tom, co konkrétně potřebujete.

      S pozdravem,

      Hello @csacher,
      this interval is not changable and it is based on the way the Mervis polls the data from sensors. It doesn't use the broadcast reading, but instead it reads each sensor separately. This way of reading is more resistant to errors.

      Best regards,
      Martin

      Dobrý den @linex,
      direct switch se používá pouze pokud potřebujete na HW úrovni propojit digitální vstup s odpovídajícím digitálním / reléovým výstupem.

      Pokud tedy vyloučíme tu část týkající se DS, pak by měl být výstup za ORem i za togglem po startu v 0.

      Studený start dělá přesně to, co popisujete.

      S pozdravem,
      Martin
