This section shows an example of the program to read 11-word data from the buffer memory address 400
the AJ65BT-R2(N) (station number 63) to the area starting from D40 in the master station when M1 is turned on in the
following system 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).
