B.6 Operating Mode Modbus Registers
Tables B.13 to B.18 detail the contents of the Modbus registers
accessible while the instrument is in the operating mode.
Two data types are used:
32-bit single precision floating point data in IEEE format
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.
