2.3 [MNET Servers]
This section contains database offset information used by the servers when
accessed by external clients. These offsets can be utilized to segment the
database by data type.
2.3.1 Float Flag
Yes or No
This flag specifies if the floating-point data access functionality is to be
implemented. If the float flag is set to Yes, Modbus functions 3, 6, and 16 will
interpret floating-point values for registers as specified by the two following
parameters.
2.3.2 Float Start
0 to 32767
This parameter defines the first register of floating-point data. All requests with
register values greater-than or equal to this value will be considered floating-point
data requests. This parameter is only used if the Float Flag is enabled. For
example, if a value of 7000 is entered, all requests for registers 7000 and above
will be considered as floating-point data.
2.3.3 Float Offset
0 to 4999
This parameter defines the start register for floating-point data in the internal
database. This parameter is used only if the Float Flag is enabled. For example,
if the Float Offset value is set to 3000 and the float start parameter is set to 7000,
data requests for register 7000 will use the internal Modbus register 3000.
