Register Address Ranges
All points are available in three separate address ranges.

Unsigned Integer
o
Point number as represented by the function block numbers
o
Typically used for digital values
o
DI (Discretes) & VDI, DL, DO (Coils)

IEEE Floating Point
o
Point number x 2 + 1000
o
Example: point 25 is IEEE register 1050 (45 x 2 + 1000 = 1050)
o
Recommended range for any analogue values, because linearization table scaling is
automatically applied
o
UI/AI, (Input Registers) & VUI, AL, CL, AO (Holding Registers)

Priority level setting: Point 500
o
Priority setting for point 25 is by writing to register 525 (25 + 500 = 525)
o
In this register range you may read the active priority level, as well as for writing a
priority level

Some point types may be configured as digital or analogue action and so, may have
alternative Modbus Function types available
