Program example

This section shows an example of the program to write 1-word data from D10 in the master station to the buffer
memory address 111
configuration.
• Assume that the I/O number of the master station is X/Y00 to X/Y1F.
• Assume that SW0 is set to the refresh device of the link special register (SW).
• M11 is the G(P).RISEND instruction executing flag.
• Assume that the settings of the interlock signal storage device are Request device: RY4, Completion device:
RX4, Error code storage device: RWr1, and Completion mode: 1.
