7. Sensors
Sensors (software objects) record and administer operational states such as voltages, temper-
atures, and other parameters of the MCH and AMC modules. Sensors effect certain events
when changes occur which result in the recording of entries in the System Eventlog.
For each sensor there is a Sensor Data Record (SDR) which describes the sensor type, the
sensor name, limit values, hysteresis, unit, etc. Furthermore, the implemented possibilities for
event origination are defined.
7.1 MCH Sensors
The MCH has sensors for measuring its own voltages, temperatures, and other states. Other
MCH sensors record for example the Hot Swap state of all controlled AMC modules.
For OEM (Kontron) specific sensor types and reading types in the following table, refer to the
next chapter.
