hi,  
In my project, I was trying to set the OPC UA Subscription with two intervals using specific variable value [true] from the read information received from the opc ua Client.and as soon as the value of variable changes to false need to have a subscription with the longer interval.  
Tried to using msg.payload , no luck yet.

1. Can you please advise me on the nodes i need use to achieve two different intervals to the OPC UA Subscription node ?
2. On my flow, on the subscription method to read, I tired using template and CSV node to configure all the data in one place, but was ended up with an error, I think, Stringarray data type is creating a problem
3. Can you please suggest me in using the right method to use template and csv node for the Subscription method ?
4. Also, while writing, it's creating an error if i use data type as StringArray, can you please suggest me the method i should use with the proper data type [stringarray] ?

_Best Regards,_
