The program part enclosed by the dotted line 2) is required only when the initial setting is changed.
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.
