@dominik Please post the your project files, where this doesn't work.

Hello @dominik,
that works:

What numeric type is the div_Temp?

Hello @robl,
the change you have made is a change of the configuration of the PLC which has to be uploaded to take affect:

Please be aware of the network settings, which by default will change to IP of the PLC to the static 192.168.1.121

Hi @joerg,
the UniPian image is indeed broken and not just the download file. There are problems inside, so we removed it from our website and until further notice, it will not be available.

You can use stock Raspbian and just to install our packages. To learn how, read this tutorial: https://kb.unipi.technology/en:sw:04-unipi-firmware

Best regards,

Hello @giamba ,
please do a proper screenshot of whole window, so we can see the error results. There are probably different variable types, but it is impossible to tell from the cut out.

Thank you,
Martin

Hi @msoenen,
there could be two major reasons. Make sure, that you have selected the HMI template in the PLC properties. Also when deploying the solution, there is a option to include the web files into the deployment, which is by default unchecked. Try reading this article how each of the mentioned options is done: https://kb.unipi.technology/en:sw:01-mervis:creating-simple-hmi-hidden

@beny44 Takto se chovají funkční bloky, které si vyrobíte sám. Připravujeme na toto téma tutoriál, který bude dostupný na http://kb.unipi.technology

Hello @martin-trojan, this isn't as easy as it looks like. We are preparing a solution as we speak and we will get back to you as soon as possible.

Thanks for your patience,
Martin

@beny44 Jsme rádi, že Vám vše funguje a děkujeme za námět na článek:)

S pozdravem,
Martin a zbytek UniPi

Hi @alydersen,
it is hard to tell what's wrong without the access to the setup. Would it be possible to arrange SSH access to the PLC? We can go over the details via email: support@unipi.technology

Hi @dnevin,
do you have the UniPi Neuron driver for CODESYS (https://store.codesys.com/unipi-neuron-for-codesys-sl.html)?

Martin

Hi @joerg,
you have discovered, that the neuron-kernel is built specifically for each version of the raspberrypi-kernel. Since we don't get pre-release information about new version of the raspberrypi-kernel, the dependence of our package is broken until we make new version.

To overcome this issue, we have a package unipi-kernel-modules-dkms which builds the kernel module from the sources. So when Raspbian issues new kernel, the package will rebuild the module upon the up-to-date sources.

To use the dkms simple uninstall the neuron-kernel package and install the unipi-kernel-modules-dkms.

Best regards,
Martin

Hi @clueless,
just to be sure, can you please post some photos of your sensor connection?

Thanks,
Martin

Dobrý den @beny44,
obávám se, že na našem fóru nenaleznete nikoho, kdo by toto řešil. Jak jsme se bavili po emailu - zkuste kontaktovat přímo vývojáře Mervis platformy: https://kb.mervis.info/doku.php/cs:help:still-cant-find

S pozdravem,
Martin Kudláček

@beny44 Mervis má spoustu bloků pro konverzi mezi datovými typy. Zkuste je prozkoumat: Basic Analogue Boxes -> Type Casts.

Dobrý den @Beny44,
zkuste si zreprodukovat tento projekt:

Dobrý den @beny44,
chápu to správně, že z elektroměru dostanete kumulativní spotřebu od momentu jeho zapojení a chcete z této hodnoty přepočítat spotřebu za aktuální den?

S pozdravem,

Hello @alydersen,
the way you describe it seems that you have done everything correctly. What sort of issues do you experience? What software do you use? How does the RX/TX leds look like when the issue occurs?

The L513 act as a master of the ModbusRTU communication, therefor it doesn't have any address.

Best regards,
Martin

Dobrý den,
je nám líto, ale podporu pro Mervis poskytujeme pouze k našim produktům.

Děkuji za pochopení a přeji pěkný zbytek dne,
Martin Kudláček

Hello @tazok,
can you please explain a bit more what are you trying to achieve? What SD card image do you use? Do you run it on sole RaspberryPi or do you use some of our units?

Thanks,
Martin
