[Word information from the master station to all local stations]
9) The program uses the mdSend function to write the word information to the
"remote register RWw" buffer memory of the master station.
The remote register RWw is used as the word information for writing to be
used by local station systems.
10) The information in the "remote register RWw" buffer memory is automatically
stored (for each link scan) in the "remote registers RWr" of all local stations.
The remote register RWr is used as the word information for reading to be
used by local station systems.
11) The word information stored in the "remote register RWr" buffer memory is
stored in the CPU device set with automatic refresh parameters.
