Recently I tried to catch the value of a displacement sensor from the OPC UA node, may I know why i receive the null value. May i know is there anyway to configure the data so i can receive a correct value?
I'm afraid there is nowhere near enough information to help. Anything we tell you would be pure speculation.
If you want further assistance, please provide details like version numbers, what you have tried, screenshots etc.
Have you checked console or status code that server will return?
