3.5.3 Sensor data block
The data block contains the data of the sensors in the order of their reg

istering on the IQ S

ET
(Sxx number).
The data of a sensor are stored in 8 registers each.
Thus, the sensor data block consists of altogether 16 registers. Each
register contains 2 bytes. The bytes 0 and 1 form register 0001, the
bytes 2 and 3 form register 0002, etc.
