Configure MQTT Client

1. Navigate to Devices → Protocols
2. Select MQTT Client
3. Create channel:
   • Name: MQTTClient
   • Protocol: MQTT Client
   • Settings:
     • Broker URL: test.mosquitto.org (or your broker)
     • Port: 1883 (or 8883 for SSL)
     • Client ID: FrameworX_001
     • Keep Alive: 60 seconds

---

Set Authentication (if required)

For secured brokers:

• Username: Your username
• Password: Your password
• SSL/TLS: Enable if using port 8883
• Certificates: Browse to certificate files

Subscribe to Topics

1. Go to Devices → Nodes
2. Create subscription node:
   • Name: IoT_Sensors
   • Channel: MQTTClient
   • Subscribe Topic: sensors/+/temperature
   • QoS: 1

The '+' wildcard subscribes to all sensors.

---

Create Points for Subscribed Data

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

Temperature Sensor:

• Name: Sensor1_Temp
• Node: IoT_Sensors
• Topic: sensors/sensor1/temperature
• Data Type: Double
• JSON Path: $.value (if JSON payload)

Humidity Sensor:

• Name: Sensor1_Humidity
• Node: IoT_Sensors
• Topic: sensors/sensor1/humidity
• Data Type: Double

---

Publish Tag Values

1. Create publish Device Channel and Node:
   • Protocol: MQTT Publisher 
   • Name: SCADA_Publisher
   • Publish Mode: On Change
2. Configure published points:
   • Tag: Select tag to publish
   • Topic: scada/line1/production
   • QoS: 1
   • Retain: True (optional)

Test Connection

1. Start Runtime
2. Open Devices → Monitor
3. Use MQTT client tool (like MQTT Explorer) to:
   • Publish test messages
   • Verify FrameworX publishes

Next Steps

• CONNECT (Reference) - Explore list of connectors
• [Enrich Data & Scripts] - Process MQTT data
• [Secure & Deploy] - Production security
