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 AJ65VBTCU-68ADV/ADI to the
master module, and remote outputs (RY) mean the output signals from the master
module to the AJ65VBTCU-68ADV/ADI.
In communications with the master station, the AJ65VBTCU-68ADV/ADI uses 32
points of the remote inputs (RX) and 32 points of the remote outputs (RY).
This module occupies three stations but do not use the latter 64 points.
Table 3.4 indicates the assignment and names of the remote I/O signals.
