Cause and
correction
Assumed cause Correction Prevention
The upper limit of the data size was
exceeded.
If an event on restrictions on the num-
ber of items used occurred at the
same time as this event, correct the
user program and settings so that the
number of items used is not exceeded
and then download the data again.
None
The main memory capacity was
exceeded.
If an event on restrictions on the num-
ber of items used did not occur at the
same time as this event, perform the
Clear All Memory operation, cycle the
power supply, and then confirm that
this event was cleared. If it was
cleared, reduce the size of the proj-
ect, e.g., by sharing programming,
and then download the project again.

or has failed.
If this error persists even after you
implement the above two corrections,
replace the CPU Unit.
