Overview

Industrial sites often run mixed equipment — PLCs, sensors, and gateways speaking different protocols. In 2025 we delivered an integration layer that bridges Modbus (TCP/RTU) and MQTT so operational data can flow reliably into a single monitoring and control stack.

We mapped registers and topics into a consistent data model, handled reconnects and buffering for unstable networks, and exposed clean APIs and dashboards for operators. The result is faster commissioning of new devices and fewer custom one-off connectors.

Modbus remains the workhorse for plant-floor devices, while MQTT carries events and telemetry to the cloud and edge services — together enabling scalable IoT without rewriting existing automation.
