Word wise swapping

In word wise swapping, the third and fourth bytes are interchanged in
order with the first and second bytes. This results in a byte order of
3 4 1 2. The byte order complies to the IEEE Big Endian floating point
definition.

Error and status indicators

Error and status words follow the same standard definition for all sc
probes and controllers.
Table 7 lists bit position and error messages.
and status messages.
A bit value of zero shows the error or status condition that is not true.
4 Exponent
5 Mantissa
Table 8 lists bit position
A bit value of 1 shows the error or status condition that is true. For
example, if Bit 0 has the value of 1, an error has occurred during the last
calibration.
