From the drop down
menu, select the
Register Data Type
• Float
• Unsigned 32
• Signed 32
• Unsigned 16
• Signed 16
• Bit Packed
• Single Bit
If read as an integer,
the output is converted
to a floating point.

Registers –
Function Code
04
Function code 03 or
Function code 04 is
used to read the
contents of input
registers in the slave.

Function Code
02
Function code 01 is
used to read a slave's
coil's (discrete output's)
ON/OFF status of the
slave device in a binary
data format.
Function code 02 is
used to read a slave's
input's (discrete
input's) ON/OFF status
of the slave device in a
binary data format.
Output is floating point
equivalent (0.0 or 1.0).
NOTE: Refer to the
Communications
manual for the function
codes supported by the
specific device.

Select which bit (0-15)
to read when Register
Data Type = Bit Packed
0 to 15
If read as a bit packed
number, you must
select which bit to
mask (0-15).
The output will be the
floating-point
equivalent (0.0 or 1.0)
of the masked bit.
