Master programming: In a program, D1110 can be used to define a slave station to be
controlled (1–8, if set as 0, can jump between 8 stations). Afterwards, M1035 is set as 1, and the
memory positions of the master and slave stations will correspond. At this time, it is only necessary to
send commands to the correlation slave station address to control that station. The following is a
register table connected with internal communications:
