I : Integer, 0 – 10000 (0 – 100%)
F : Floating (32-bit data cannot be accessed using fl oating 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
OUTPUT MODE
1
0
Main bus is used; Red LED turns on at RUN LED of the I/O modules.
0
1
Sub bus is used; Green LED turns on at RUN LED of the I/O modules.
1
1
Main bus is used; Amber LED turns on at RUN LED of the I/O modules.
0
0
Output is invalid; RUN LED of the I/O modules turns off.
• Writing to Coil (0X) and Holding Registers (4X) is only available with either Wireless or Modbus communication. It is available
to change the confi guration with Confi gurator Software (model: R3CON). Factory default setting is Modbus communication.
