POSITIONING DEDICATED SIGNALS
The internal signals of the Motion CPU and the external signals to the Motion CPU are used as positioning signals.
Internal signals
The following five devices of the Motion CPU are used as the internal signals of the Motion CPU.
MELSEC iQ-R Motion device assignment and Q series Motion compatible device assignment are available. The ranges used
for devices differs depending on the device assignment method used.
Refer to the following for details on device assignment method.
