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-68DAVN to the
master module, and remote outputs (RY) mean the output signals from the master
module to the AJ65VBTCU-68DAVN.
In communications with the master station, the AJ65VBTCU-68DAVN uses 32 points
of the remote inputs (RX) and 32 points of the remote outputs (RY).
The number of stations occupied by this module differs between ver. 1 remote device
station (ver. 1 compatible slave station) setting and ver. 2 remote device station (ver. 2
compatible slave station) setting.
3 stations are occupied in the case of ver. 1 remote device station (ver. 1 compatible
slave station) setting. The latter 64 points are not used.
1 station is occupied in the case of ver. 2 remote device station (ver. 2 compatible
slave station) setting. Expanded cyclic setting is fixed to quadruple and the latter 32
points are not used.
