(b) Enabling synchronous processing with a motion control
An interrupt program which is synchronized with the operation cycle of a motion
controller (multiple CPU synchronous interrupt program) can be executed.
Command I/O from a motion controller can be synchronized with the operation
cycle of the motion controller, which enables high-speed data transfer
independent of scan time.
