Omnicomm LLS 5 fuel level sensor is supported on Xirgo Global devices with RS232 or RS485 communication.

1. Physical Connection

Omnicomm LLS5 wire color coding:

When wiring in fuel sensor you should select between RS232 and RS485 communication. RS232 allows single sensor to be connected, RS485 allows multiple, but sensor needs to be configured to have different network address.

1.1 RS232 Connection

To connect Omnicomm LLS 5 fuel level sensor to Xirgo Global devices 4 wires needs to be connected, 2 power wires and 2 RS232 communication wires.

At once only one peripheral can be connected through RS232 device.

2. Adjustments In Configuration

2.1. Adding Script

In configuration template ‘Script'->’Script1'->'Script' select ‘BCE_MEAS_LLS-FUEL-Sensor-SCR-1_8’ script. When script is added script settings will appear below

Open

2.2. Configuring Script Peripheral Settings

In newly appeared tab ‘Peripheral Settings' select ‘Peripheral Interface’ should be selected same as sensor was wired ‘RS232’ or ‘RS485’ and ‘Peripheral Baudrate, bit/s’ as '19200’

2.3. Configuring Script LLS Settings

‘Network Address’ by default is set to ‘1' both in LLS5 sensor and script configuration, when connecting single through RS232 this parameter doesn’t need to be changed.

If sensor is connected by RS485 when using single sensor ‘Network Address’ parameter doesn’t need to be changed. However if using multiple LLS5 sensors connected through RS485 'Network Address' needs to be changed to one that was configured in LLS5 sensor, more about sensor configuration read paragraph 3. LLS5 Documentation.

For ‘Temperature, °C', ‘Relative level’, 'Frequency’ select desired sensors where values will be saved, take note of selected sensors.

For this example we choose:
Temperature - sensor 16389
Relative fuel level - sensor 16390
frequency - sensor 16391

2.4. Displaying in Monitoring platform

For device to report sensor values to telemetry platform sensors needs to be included into telemetry payload.
