Page 3: Introduction And Overview
• A Modbus TCP master device (typically a computer or PLC) connects to the bridge via local area network (LAN) and polls the bridges for sensor data. •... -
Page 4: Hardware & Networking Requirements
Each bridge supports up to 32 sensors in stand-alone mode Supported LAN networks To work in the Modbus TCP mode, the bridge has to be set-up for Ethernet or WiFi network connectivity. A bridge configured for cellular network connectivity does not support Modbus TCP. -
Page 5: Modbus Parameters
Another option is to set the real-time clock via the Modbus Interface. This will override any time retrieved during the boot process. Modbus parameters These parameters are needed when setting up the connection from the Modbus Master: • The bridge Modbus interface is enabled via TCP port 502 •... -

Bridge Modbus Software Model Modbus Register Map This section is for use by the Modbus Host programmer. The image below shows the bridge register map as reflected to the Modbus Master: Register # Functional Size (16 bit Type Description Format Comments (Dec) Code... -
Page 7: Sensor Slot Allocation Example
We can also see another sensor (S/N 55555555) which is received by the bridge but has not been allocated to any slot. This sensor data will be ignored when the bridge is in Modbus TCP mode. In ‘PowerRadar connected mode’ or ‘combined mode’ all sensor data is simultaneously sent... -
Page 8: Sensor Readings
Sensor Readings As seen in Figure 2 above, each sensor slot contains sensor data. This section will review and explain the sensor data stored for each slot. Figure 3 Sensor data storage As seen in the image, each sensor slot reserve 40 bytes of memory and store the following values: •... -

• Manual calibration key retrieval – In the rare case where internet access is not available during bridge configuration, please contact powerradar-support@centrica.com with the serial numbers of sensors needed. A file containing the respective calibration keys will be provided to be manually entered into the bridge. -
Page 10: Bridge Configuration For Stand-Alone Mode
2. By default, the bridge is configured to connect to PowerRadar 3. Check ‘Enable Stand Alone Modbus TCP’ to enable the Modbus TCP option. 4. Note that it is possible to set both ‘PowerRadar’ and ‘Modbus TCP’ modes concurrently. In this case: a. -
Page 11: Define Bridge Ui Accessibility
Figure 5 The Connection Setup Screen Define bridge UI accessibility For enhanced security, the bridge UI is accessible by default only during configuration mode, using a wired-connected laptop. It is possible to change that configuration, making the UI accessible from any laptop in the same LAN as the bridge. -
Page 12: Assign Sensors To Slots
Type the calibration key if you have it or click ‘Get calibration key’ to have it automatically retrieved and inserted. 4. The sensor is now assigned to the slot. New readings will be shown in this screen and made available via the Modbus TCP interface. Figure 7 The Sensors Tab Figure 8 Add Sensor Pop-up... -
