Hi,
It could be many ways how to do this, but the easiest would be running a HTTP(S) or MQTT protocol server on your virtual server and then with Modbus TCP functionality query data from itself, which then you can send to the server using Modbus Data to Server functionality.
So set-up RUT240 as a slave and a master in Services > Modbus, set it to query itself, and then just configure Data to server.
The part where you convert data between your own virtual server is on you, there's nothing much RUT240 can help you after it sends data.
