Appendix: SP-006 Registers 

The following Appendix provides the registers and list index for the Layer N SP-006 Pressure monitoring Smart Probe. This 

information is intended to aid users who will be making configurations and adjustments to their Layer N SP-006 Pressure 

monitoring Smart Probe through the Command Line Interface or other custom interfaces. 

6.1

 

Register Base Addresses 

Smart Probe devices share a common platform architecture that provides extensive monitoring and control 

capabilities through a set of platform generic registers. These registers may be accessed using I2C based commands 

directly to the Smart Probe devices or through a set of Modbus-based registers when using Omega Interface devices. 

Refer to the 

Smart Sensor Device Interface

 manual for further information. 

When powered on, or after a device reset, each Smart Sensor-based device will enumerate 1 or more sensor 

instances which are described by the device-specific Sensor Descriptors which include configuration options, 

measurement type, and units of measure for the corresponding sensor values. Additional sensor information is 

provided in sensor-specific IPSO object descriptions which include extended measurement type, precision, and 

tracking of minimum/maximum readings.  

Sensors are always enumerated in the order Pressure, Temperature (T), and DIO.

 

Each enumerated Sensor has a Descriptor Base address location and a Sensor IPSO / Configuration structure address 

location based on the sensor mix selected.

The SP-006 configures the sensors based on the factory device list and user-specified list index. The Sensor 

Configuration and Sensor Device fields may be written to provide control of the overall function of the channel
