B.4.2 Operating Mode Modbus Registers
Tables B.18 to B.39 detail the contents of the Modbus registers
accessible while the instrument is in the operating mode.
Two data types are used:
n 32-bit single precision floating point data in IEEE format
n 64-bit double precision floating point data in IEEE format
Note. When writing to a parameter that occupies more
than one register position then all registers relating to that
parameter MUST be written to as part of a multiple register
write. If this is not achieved a NAK exception response is
issued. Individual registers can be read without causing an
exception response.
When accessing a parameter that occupies more than one
register position, the lowest numbered register contains the
most significant data.
