range. (There is no
need to power up
again or to restart the
Unit.)

Data range error
Unit address stored in
DM Area
The lowest DM
address where the
out-of-range error
occurred is stored,
in four digits hexa-
decimal, as the off-
set value from m
(i.e., the number of
added words).
If there is no other
error, 0000 Hex is
stored. (If there is
another error, the
offset value for that
DM address is
stored.)
