(1) Data flow
This section describes the data flow and the setting for cyclic transmission of word device data.
• When transferring data from the Motion controller to the head module: The remote register (RWw) data of
the Motion controller is transferred to the buffer memory of an intelligent function module connected to the
head module.
• When transferring data from the head module to the Motion controller: The buffer memory data of the
intelligent function module connected to the head module is transferred to the remote register (RWr) of the
Motion controller.
