4.2.2 Communication with the remote device stations
This section explains an overview of the communication between the master station
and the remote device station.
In the communication with the remote device station, the handshaking signals with the
remote device station (initial data processing request flag, error reset request flag, etc.)
are communicated using the remote input RX and remote output RY. Numeric data
(averaging processing specification, digital output values, etc.) is communicated using
the remote register RWw and remote register RWr.
