Reconstruction of Positioning Data by User Programs

Recalculation
Recalculation is necessary after rewriting positioning data using user programs. The
procedure of recalculation is as follows. When recalculation is not performed, the operation is
executed with the positioning table before rewriting.
1. Change the positioning table in the unit memories.
2. Turn on the recalculation request (Y7) in the I/O area.
3. Confirm that the recalculation done flag (X7) in the I/O area is on. (Confirm that the
recalculation process is completed.)
(Note): I/O numbers of the recalculation request (Y7) and recalculation done flag (X7) vary according to the value of
the "Starting word number" allocated to FP7 MC Unit.

The recalculation done flag turns on when the recalculation by the recalculation request is
completed. After that, the recalculation done flag turns off when the recalculation request
signal turns off.
REFERENCE
For details of the areas used for rewriting positioning data, refer to "16.7.4.1 Control
Area for Buffer Control" and "16.7.4.2 Positioning Data Setting Area".
For details of the area used for the recalculation process, refer to "16.5.2 Setting
Parameter Control Area".
The units used for the recalculation process are as follows.
