Hi,

Thank you for that article. I was aware of how exactly Node-RED works and why they have selected this approach. I am also familiar with many other frameworks, such as Vykon Niagara and Siemens AF. I wanted to avoid any discussions as enough has been said throughout this forum.

It is my mistake for not being clear on what side I am and what type of plugin I was making.

Apologies

And I have some different perspectives about multiple inputs in subflow node. In an example like the one below,multiple inputs will be more convenient.

> Good morning everyone, I am using Node-Red with OPCUA to connect to a controller and display the values in their own gauge to the dashboard. I was wondering if there may be a better way to do this. My thinking is that it is not necessary to create an OPC UA Client node for each OPCUA Node that I want to read. I also wonder if this is creating a separate connection for each node that I want to read. Can someone please advise if my thinking is correct and if there would be some way to use only…

> I am including several production lines into my data-gathering program. They use OPC-UA to offer me the information. Single parameter readings are not a problem anymore: I send the nodeid for the parameter I want to read, and I get a message with that single parameter. This is fine. However, we have 3 production lines (times 3) and we're talking about reading hundreds of parameters. Having a full message for each one will be an incredible overhead, so I want to use the read multiple function. T…
