the pointer to the storage area.
If the data to be downloaded has been copied to
DM 0000 to DM 0119, the Cam Positioner Unit is
in RUN mode, downloading is enabled, and the
current download has not been completed, the
Memory Download Bit is turned ON to download
the data in DM 0000 to DM 0119 to the Cam
Positioner Unit.
Also, contents of 120 words of data starting at the
address in DM 5000 (initially DM 3000) are copied
to DM 0000 to DM 0119.
When b turns ON, #0200 is added to the pointer
value in DM 5000 to change the first word for
transfer to DM 0000 to DM 0119.
When the download has been completed, the
Memory Load Completed Flag (IR 10804) turns
ON and b is turned ON for one scan.
Contents of pointer value in DM 5000 compared to
#4200 to see if all the data has been downloaded.

If DM 5000 contains #4200, d is turned ON and
the download processing is stopped.
