What it does
Give your local SCADA or HMI access to Modbus devices without any internet path. The bridge polls your RS-485 devices and presents them on the LAN for your control room to read — and to write. Setpoints, commands and coils pass through to the field device as they would on a direct connection.
Typical sites: defence · pharma and GMP · government tenders · panel retrofits.
The point of it
“No internet” here is a property of the product, not a configuration choice. There is no cloud capability in it to disable, and none to audit away. For sites where connected hardware is prohibited outright, that distinction is the whole requirement.
It is also what makes two-way control appropriate here. Our cloud gateways are read-only by design, because a device reachable from the internet should not be able to write to a live process. This bridge is never reachable from the internet, so control can stay where it belongs — with the operators in the building.
Choose this when
Your site forbids internet-connected hardware, or you simply do not need the cloud. If you later want cloud reporting, that is a different product — not a licence key.
