Hello,
From what you have posted, it sounds like you would be interested in a "Mango Data Publisher" which would forward on the Modbus data gathered by Mango into other systems.
While this is entirely possible, we currently do not have this on our development roadmap.
If this is something of real commercial interest and value to you, perhaps you could consider sponsoring some development work to advance this. If so, please do not hesitate to contact us to learn more about this option.
Regards,
