reset, the data may be output without being cleared to 0, depending on the timing of the cyclic data transfer processing and
link refresh.

GX Works3 Operating Manual
■ For link refresh to RX, RWw, RWr assigned to the Motion control station
• The refreshed value for RY/RWw assigned to the motion control station is not reflected in the output to the motion control
station. Additonally, when operating in multicast mode, the value refreshed to RY/RWw assigned to the motion control
station is not stored in the local station link device (RX/RWr).
• When refreshing RX and RWr, the value (initial value 0) written last by direct access, etc. of the link device is stored in the
CPU side device for RX/RWr assigned to the motion control station.
