Like the attached file, I want to redundancy
If possible, please tell me how to do it.
As far as I know, Device has no redundancy.
But you can create duplicate tags and choose which set of values to use ,based on the connection state.
How should I do that?
can you tell me?
Here is a rough example. Get the device state and use it to build the real tag's path.
Using UDT will help a lot.
New Tag expression
Thanks for letting me know
Another solution is to use 2 opc tag and a reference tag with the sourceTagPath according to the device connected.
Yes, that's better.
