    • Protocol: MQTT Client
  4. Go to Device → Nodes
    1. Name: IoT_Sensors
  5. Open PrimaryStation and configure:
    1. BrokerURL: 127.0.0.1
    2. Port: 502
    3. ClientID: FrameworX


2. Create Points

  1. Navigate to Devices → Points
  2. Add points for each expected topic:

Temperature Tank 1 Sensor:

  • TagName: TankFarm/Tank1/Temp
  • Node: IoT_Sensors
  • Topic: TankFarm/Tank1/temperature
  • AccessType: Read

Temperature Tank 2 Sensor:

  • Name: TankFarm/Tank2/Temp
  • Node: IoT_Sensors
  • Topic: TankFarm/Tank2/temperature
  • AccessType: Read

Temperature Tank 3 Sensor (write):

  • Name: TankFarm/Tank3/Temp
  • Node: IoT_Sensors
  • Topic: TankFarm/Tank3/temperature
  • AccessType: Write


3. Test Connection

  1. Start Runtime
  2. Open Devices → Devices Monitor
  3. Use MQTT client tool (like MQTT Explorer) to:
