: Items that needs resetting after conversion due to partial differences in functions/specifications.
× : Items to be deleted because there are no common items between the A0J2HCPU and QCPU.
Confirm the contents after conversions, and correct/reset if necessary.

Resetting is necessary.
Becomes default (output before STOP).
Resetting is necessary.
Resetting is necessary as the specifications differ.
Becomes the number of default points.
As the number of default points exceeds the number of
A0J2HCPU points, program correction is unnecessary.
M and L are separate devices.
"L" on the program is converted just as "L".
Converted as a single device.
As the latch range is the entire range from the minimum device
number to the maximum device number, it must be reviewed.
