Siemens Logo!, AWS and Virtuino IOT

[Grinkor]

Hi! I´m Max from Argentina. I´m using Virtuino IOT to manage a Siemens Logo! 8.3 via Modbus. It works like a charm inside my client´s LAN.
But, I have to control it also from Internet. The LOGO! is registered in AWS IOT and I can see its shadow working properly.

I know Modbus but I´m still new to these new IOT technologies.

Can Virtuino interact with an AWS thing´s shadow via MQTT? 
Or, is there a more practical way to control these PLCs from internet with Virtuino?


Thanks!
