7 Appendix: SP-013 Registers
The following Appendix provides the registers and list index for the Layer N SP-013 Digital Input Smart Probe. This
information is intended to aid users who will be making configurations and adjustments to their Layer N SP-013 Digital
Input Smart Probe through the Command Line Interface or other custom interfaces.
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.
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.
Each enumerated Sensor has a Descriptor Base address location and a Sensor IPSO /Configuration structure address
location based on the sensor mix selected.

Digital Descriptor
The SP-013 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 and
the signal types used.
