Lost Holding Register Data every time I deploy project on Node-RED

I am working on MODBUS-Server Node And used one IP address to configure & Connect it via Master Device.
Every time I deploy Project on Node-RED Server , I lost my Holding Register Data.

Try setting it to only deploy modified nodes (click the little down arrow on the deploy button).

If that doesn't work, you may want to try saving the data in a context variable. This way, the data can persist in memory, or even a file.

I actually Tried that i.e, Deploy modified nodes but result doesn't change.
I have to restart my Physical device only then It shows me Data Again.
Actually I don't want to save data , I just want it whenever I deploy changes in project Like I am not even touching Modbus Server Node, it fetches me the data so that I play with that.
