Hi Mikhail,

I configure the Device Properties like below:

I created a JS file and locate at C:\Program Files\SCADA\ScadaComm\Config as suggest:

The only thing I couldn’t follow is the Sub items which I don’t know what to fill into the String Collection Editor. My String Collection Editor is different from those from forum example.

I got error:

As the result, I couldn’t get the Voltage L1, L2 and L3 values:

Need your advice on how to complete my configuration.
Thank you.

Hi,
You need subitems as Voltage L1, Voltage L2 and Voltage L3. And only 1 subscription,

Hi Mikhail,

Could you give example of how to write in subitems for my case?

Hi,
Create only 1 subscription, named Voltage (delete 2 others). The subscription should contain 3 sub items (3 lines).

Hi Mikhail,

That’s great. I can read all the Voltage L1, L2 and L3 now.
Thank you.

Could you share the final settings? It can be useful for other users.
