B.5 Operating Mode ModbusTCP Registers – Tables B.11 to B.13
Tables B.11 to B.13 detail the contents of the ModbusTCP 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.
Read Only, single
