•Axis 1 to 4 status information (M2400 to M2495) is transferred to the automatic refresh area one every operation cycle of the Motion CPU.

•Axis 1 to axis 4 command signals are received from the automatic refresh area one every operation cycle of the Motion CPU.

•Real current values of Axis 1 to axis 4 and M-code is updated by setting D0 to D639 of the Motion CPU to the automatic refresh area.

•Every 0.88ms, data in the automatic refresh area of all CPUs are transferred allowing each CPU to update its data upon its next independent operation cycle.
