Kvd (Key ValueDatabase App) - how to create an array

[tszalkai]

I am wondering if anybody knows how to create an array of UINT16 in the Kvd's nodes.json.

In the Kvd manual I found little information on arrays. It's supposed to be 

aruint16                     array of unsigned int (16 bit)

, but the syntax below not work. I imagine the length of the array needs to be defined, I just don't know how to.

{

            "address": "Folder/TagName",

            "type": "aruint16",

            "metadata": {

                "nodeClass": "Variable",

                "description": "Description"

}

Hello,

you don't need to set an array length it increased/decreases automatically when you write data into the array.

I created a array, similar like yours

and it's empty by default.

I write some values and press save

 and the values are written and the array size increased from "0" to "7".

If you want to access such an "empty" array via OPC UA, it's the same. The size increases automatically when I write some data (I used the UA-Expert).

 

I write only "0" for all 4 elements

and the array has increased with the written values.

Thanks for the detailed response.

Unfortunately, my structure looks differently, see below.

 {

            "address": "Nexeed/Faults",

            "type": "aruint16",

            "metadata": {

                "nodeClass": "Variable",

                "description": "For the Nexeed Virtual Assist"

            }

resulted

I am running the latest 1.20.
