If the user already has a register map with all their registers, they can upload one using the Upload button.

Once selected, the user will be prompted with the below pop up to find their CSV Register Map.

Once selected, the user will able to see the register map available in the grid view and on the left tree menu under "Register Maps".

From here, the user can then select the uploaded register map on the left side to edit registers if needed or add more.

Note: A "ping" register is required and needs to be a valid ping register in order to test connectivity to the slave. Modify it to match a register that exists or if you know what it is change it to that.
