Data range error address
stored in DM Area
While the power is ON, an
out-of-range setting is set in
the continuously refreshed
area.
The Unit will continue operat-
ing with the original continu-
ously refreshed area data.
ERC indicator is lit.
RUN indicator remains lit.
The lowest DM address
where the out-of-range error
occurred is stored, in four
digits hexadecimal, as the
offset value from m (i.e., the
number of added words).

Leave the power ON and
change the setting to a valid
value.
The Unit will operate with the
edited settings in the contin-
uously refreshed area.
ERC indicator is lit.
RUN indicator remains lit.
If there is no other error,
0000 hex is stored. (If there
is another error, the offset
value for that DM address is
stored.)

The lowest DM address
where the out-of-range error
occurred is stored, in four

within the allowable range,
and the PLC is turned ON or
