I have a general question about the capabilities of the switch node. For example, in the screenshot attached, I am sending just about all of my OPC info through one READ node that then goes to a switch node, and using browseName I separate them and send them where they need to go. Is this too many f…

Haha thank you for pointing that out!! :rofl:

There's something different about your image - it doesn't expand when you click it - can you try just pasting the image in please (Did you shrink it before posting or something - if you did - paste the original full image instead)

When using a switch or this approach, the results depend on the iteration when it got to the result that then broke out to the output. The LAST iteration takes the longest to find, thus delay. The first, the less time, the fastest. You will need to find a method to eliminate the time taken to sea…

Do you have any suggestions on a more efficient way to do this?

It would probably be a little more efficient to check for equals rather than contains as If you use contains and the search string is short then it has to look for it anywhere in the string, not just at the start. However, if you are seeing a delay that is noticeable to the human brain then I don't…

So in that case do you think the delay is on the OPCUA side? We use node-red-contrib-opcua READ/WRITE nodes to write data to the OPC and read data coming from it...In this case, the switch node is only used for the READ

I have no idea. How long a delay are you seeing?

Can you export just the switch node and share it here, so we can see what you are doing there? In case you don't know how to do that see this post for more details - How to share code or flow json
