• 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)

R3-PC16A: External power supply in error or disconnected

• 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 con guration with Con gurator Software (model: R3CON). Factory default setting is Modbus communication.
