Operating Mode Modbus Registers - ABB ScreenMaster RVG200 Operating Instructions Manual

ScreenMaster RVG200
Paperless recorder
B.5 Operating mode MODBUS registers
Tables B.12 to B.14 detail the contents of the MODBUS TCP registers accessible while the recorder 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, 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, IEEE floating point 32 bit number
