Get Sensor Reading; Table B-11 Netfn 0X04, Cmd 0X2D - ABACO VMICPCI-7055 Hardware Reference Manual

B.1.12 Get Sensor Reading
This command returns the present reading for the sensor. Sensors are periodically scanned, and the last
reading will be immediately returned in response to this command.

Table B-11 NetFn 0x04, Cmd 0x2D

The Abaco IPMI subsystem contains several sensors. They provide the voltages and temperature
reading of the system. The various sensor settings like threshold, hysteresis, event enable, etc., are
statically configured in the Sensor Data Records.
