MODBUS I/O ASSIGNMENTS
Coil (0X)
Inputs (1X)
1025 – 1040
1041 – 1056
1057 – 1072
Input Registers (3X)
Holding Registers (4X)
I: Integer, 0 – 10000 (0 – 100%)
F: Floating (32-bit data cannot be accessed using floating addresses.)
Note: DO NOT access addresses other than mentioned above. Such access may cause problems such as inadequate operation.
• Module Status indicates whether individual I/O modules are mounted or not. The bit corresponding to the mounted slot
turns to "1," and the unmounted slot to "0."
• Error Status indicates error status for each module as described below. The bit corresponding to such module turns to "1."
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A: Power input in error or disconnected
R3-YSx: Output current error (e.g. load unconnected)
• Data Error Status indicates overrange (R3-US4: out of -10% to +110%; the other types: out of -15% to +115%) status for each
module. The bit corresponding to such module turns to "1."
• Main / Sub Switching Commands given to the network modules result as follows:
'MAIN' MODULE
'SUB' MODULE

• Writing to Coil (0X) and Holding Registers (4X) is only available with either Wireless or Modbus communication. It is
available to change the configuration with Configurator Software (model: R3CON). Factory default setting is Modbus com-
munication.
TRANSMISSION DATA ASSIGNMENTS
DIP SW located at the side of the module specifies each I/O module's data allocation (occupied data area).
For example, when the data areas are assigned as shown below:
Module 1
Module 2
Module 3
Module 4
Module 5
Module 6
Module 7
Then the I/O data are assigned as in the table below:
Input Registers (3X)
1 – 4, 257 – 264
Holding Registers (4X)
5 – 8, 265 – 272
9 – 12, 273 – 280
13, 281 – 282
14, 283 – 284
15, 285 – 286
16, 287 – 288

Coil (0X)
Inputs (1X)
For Coil (0X) and Inputs (1X), addresses 16 times assigned
data areas (Data Allocation Type) are allotted with the Data
Allocation Type '1' and '4.' With '8' and '16,' 64 (4 × 16) are
automatically allotted.
