To create a register with packed status bits.
• Copy the status registers (rows) in the Modbus map to the 3x or 4x register section.
• Enter the new register address (i.e. 30501)
• Enter the new Bit field 1 thru 16

21.6.6 Read Current Values
The channel value can be read from either Input Registers (3x) or Holding Registers (4x). The value
can be read as a 32-bit floating point value, or as a scaled value (0 to 65535). B&K Vibro
recommends using the floating-point value if it is supported by your DCS system.
Format Description
32-bit floating point
Value is read in actual engineering units (i.e. 2.5
mils)
16-bit unsigned integer
Value is read as a scaled value (percentage) (i.e. 0
to 10 mils = 0 to 65535, or 0 to 4095).
For example: Current value = 2.5 mils,
Measurement range is 0 to 10 mils (2.5 mils =
25%), Modbus range =
0-4095. Modbus Value (25%) = 1023.
Data provided as 32 Bit Floating point values use two 16-bit registers. The word order can be
swapped (see section 21.3.5)
