status M2400 to M3039 in automatic refresh are updated to Multiple CPU
high speed transmission area every operation cycle.
• The command signals of M3200 to M3295 for 1 axis to 4 axes among each
axis command signals M3200 to M3839 in automatic refresh are updated
from Multiple CPU high speed transmission area to positioning dedicated
device every operation cycle.
• The real current value for 1 axis to 4 axes and M-code among each axis
monitor devices D0 to D639 in automatic refresh are updated to Multiple
CPU high speed transmission area every operation cycle.
