I/O Signals to the Master Station

Assignment of the I/O signals and function of each signal are explained.
3.5.1
The AJ65BT-64DAV/DAI uses 32 input points and 32 output points for exchanging signals with the
master station.
An RX device indicates an input signal from the AJ65BT-64DAV/DAI to the master module, and a RY
device indicates an output signal from the master module to the AJ65BT-64DAV/DAI.

*1 Although the number of occupied stations for the AJ65BT-64DAV/DAI is
2, inputs, RX(n+2) 0 to RX(n+3)F, are not used.
However, devices for inputs, RX(n+2) 0 to RX(n+3)F, and outputs,
RY(n+2) 0 to RY(n+3) F, are reserved in the master module or CPU
module. When creating a program, pay attention to device allocation.
