4 FUNCTIONS
[Word information from a local station to the master station and another
local station]
12) The word information set with automatic refresh parameters is stored in the
"remote register RWw" buffer memory of a local station. However, it can only
be stored in the area corresponding to the station number of the own station.
13) The information in the "remote register RWw" buffer memory is automatically
stored (for each link scan) in the "remote register RWr" of the master station
and the "remote register RWw" of another local station.
14) The program uses the mdReceive function to read the word information stored
in the "remote register RWw" buffer memory.
15) The word information stored in the "remote register RWw" buffer memory is
stored in the CPU device set with automatic refresh parameters.
