3.5 Remote I/O Signals
This section describes the assignment and functions of the remote I/O signals.
3.5.1 Remote I/O signal list
Remote inputs (RX) mean the input signals from the AJ65SBT-64AD to the master
module, and remote outputs (RY) mean the output signals from the master module to
the AJ65SBT-64AD.
In communications with the master station, the AJ65SBT-64AD uses 32 points of the
remote inputs (RX) and 32 points of the remote outputs (RY). Table 3.4 indicates the
assignment and names of the remote I/O signals.
