PLC-to-MQTT Industrial Telemetry Architecture

Connect industrial PLCs directly to enterprise cloud dashboards and message brokers with zero data loss.

  • Field PLC executes process logic and updates designated telemetry data blocks/registers
  • Industrial Edge Gateway polls PLC via native Ethernet driver or Modbus TCP at configured sampling intervals
  • Edge software formats tag values into structured JSON or MQTT Sparkplug B payloads with precise timestamps
  • Encrypted TLS 1.3 connection publishes telemetry to the MQTT Broker (AWS IoT, Azure, EMQX, or HiveMQ)
