Data is transferred to
each Unit whenever an
I/O refresh is executed.
Data is automatically
transferred to each Unit
when power is ON or the
AR Restart Flag is ON.
Transferred
whenever
necessary
Refreshed once every
two to three cycles.

20 words are used.
If the unit number is 9 or less, n can be
obtained from the following.
n = 100 + 10 x unit no.
If the unit number is 10 or more, n can
be obtained from the following.
n = 400 + 10 x (unit no. – 10)
