Flow Ctrl Tech Engineering

Industrial MQTT Gateway & Protocol Bridge Suite (v4.0)

Bridge Modbus to MQTT, publish Sparkplug B payloads, monitor topics, and route telemetry from field PLCs to the cloud.

  • Bidirectional Modbus-to-MQTT Bridge: poll Modbus registers and publish structured JSON / Sparkplug B messages on schedule or by exception
  • MQTT-to-Modbus Write Channel: receive cloud commands over subscribed topics and write them directly into PLC holding registers
  • Local store-and-forward SQLite buffer: stores millions of telemetry records during internet disruptions and automatically flushes on reconnect
  • Industrial topic monitor with JSON syntax highlighting, tree-view parsing, and filter expressions
