Hi Everyone,

I try to create a SCADA project using node-red and KepWare OPC Server.  
Problem is I don't know a better way to create the list of TAGS to listen to and I have like 50 tags or more.  
Do you have a solution to replace my solution with a more smart one? A function or something...?

Thanks,  
Ovidiu
