When remote device station initialization procedure registration is to be made to multiple modules,
correct the program part enclosed by the dotted line 1 as shown below.
RX(m+1)B/RX(n+1)B indicates remote REDY, and RX(m+1)8/RX(n+1)8 indicates an initial data
processing request flag. The device number changes depending on the station number. Insert the
remote REDY and initial data processing request flags for all stations where remote device station
initialization procedure registration has been set.
