6-2-2 Scan List and PCU Area Allocations
Words are allocated to the PCU in the Work Area in the CPU Unit for use as
Axis Operating Output Memory Areas and Axis Operating Input Memory
Areas for the Servo Drives registered in the scan list. An output area of 25
words and an input area of 25 words are allocated to each axis according to
the axis number registered in the scan list. The beginning word of these out-
put areas and input areas can be set by the user in the Common Parameter
Area.
The output areas and input area allocations are specified in the four words of
data in the PCU's internal addresses from 1838 to 183B hex, as shown in the
following table. The Common Parameters settings saved in the PCU's internal
flash memory are enabled when the PCU power is turned ON or the Unit is
restarted.
The Axis Operating Memory Output and Input Areas are allocated words for
each axis from axis 1 up to the highest axis number registered in the scan list.
Axis numbers between axis 1 and the highest registered axis number that are
not registered as MECHATROLINK devices are also each allocated 25 output
words and 25 input words.
