Hello @FabioIT,
the Node-RED image is defacto a Raspberry Pi OS. You can proceed with any general tutorial for adding the desktop environment, which you can find on the offical Raspberry Pi OS webpage.

Hi @Matt,
are you sure you have selected the actual instance of the FB?

The debugging of ST code is quite "buggy". On many occasions, the values are not shown or are incorrect. We are working on a fix.

Hi @r3sist, what program cycle are you trying to achieve? Typically, you cannot get lower than 10ms.

@Jeff I replied to you over email, but for documentation purposes, I'll reply also here.

You can find the connector pinout in the official documentation: https://kb.unipi.technology/en:files:products:03-unipi_1

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

Hello @FabioIT,
the SPI is not used by the Unipi 1.1 and it is not exposed as any port. You can access the SPI on the pin header of the Raspberry Pi, but it would require to create some "hat" that goes between the Rpi and the Unipi 1.1 ribbon connector.

Hello @Neuron_Flo,
what is the source of these 4 bytes? Do you read them from some HW prototype?

Well @WesleyFranken, for Axon and Neuron, we have the image for a few weeks;) It just wasn't presented to the public, only as a download on the said page. From yesterday, we have the image for all three platforms.

Hello @WesleyFranken,
we have dedicated Node-RED images for all our PLCs. They also contain example program with Dashboard UI: https://kb.unipi.technology/en:sw:03-3rd-party:nodered

Hello @Jeff,
the input node does support reading 1-Wire temperature sensors:

Hello @ktanghe,
the port 1880 is port of Node-RED. You need to write to the port of Evok. I would suggest to download image with Node-RED preinstalled, where you will find example with Dashboard palette as well: https://kb.unipi.technology/en:sw:03-3rd-party:nodered

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.

Hello @roberts_lando,
the fix is currently in the making.

Hi @wizro_pl,
you need to write a boolean value: true or false.

Hello @juergen,
please send the serial number of your L403 to support@unipi.technology. I'll check what firmware you might be running.

Thank you and have a nice day,

Hello @msoenen,
try looking into BD86 Filter.

Hello @fabioit,
the time and date is managed by the timesyncd service. To set the timezone and disable the NTP use the timedatectl:

Hello @todward,
tha IDE 2.0 is quite ancient and it dates to the times when the HMI editor and IDE has been separated and the API has been different. In current Mervis IDE 2.3.0, the API is working:

On a side note, you can make variables available over ModbusTCP or BACnet/IP server in the Mervis 2.3.0. Maybe it will be more convenient for your other system.

Best regards,
Martin
