Guidelines on which method to use to send data between programs in a lan

Hello all,

I will have two computers, one with some data and the other one will need to modify and query that data.

This is not a database, and a database can't help at all as the data is stored into a physical machine controller (i.e. a CNC machine) and I do already have the program that harvest that data.

The harvesting program now is capable to read and write variables using their name and the value (to write) and their name and a variable (where the value is written).

I'm planning to upgrade that program to be able to answer queries from another program in another computer across the LAN so the data in computer A should be available in computer B to read and write.

Which would be the easiest way to do that using Visual C++?

I'm thinking on using sockets as it looks like the right technology to perform this task, but... is there anyone here that could guide me to a better place?

As always thank you in advance.

What I have tried:

Still nothing, I'm trying to figure out which kind of technology should I use...

As far as I have seen sockets look ok to perform what I do need...
