Precautions When Creating P Point Control

Precautions Concerning the Set Value Change Confirmation
Flag X_A
The set value change confirmation flag is turned ON and OFF at the timing noted
below, so an interlock should be applied to prevent the shared memory or other data
from being overwritten at the same timing.
Conditions for turning the flag from OFF to ON
This flag goes ON when P point control or E point control is initiated.
It goes ON at the point when the next data can be written.
Conditions for turning the flag from ON to OFF
This flag goes OFF when pulse output is completed after P point control or E
point control is initiated.
It goes OFF when the shared memory write instruction F151 is executed, and
any type of data is written to the shared memory of the positioning unit.
The interlock should be applied to each circuit, so that F151 instruction cannot be
executed and the set value change confirmation flag X_A cannot be rewritten under
any other conditions.
