(b) Synchronous processing with a motion control
An interrupt program which is synchronized with the operation cycle of a Motion CPU (multiple CPU
synchronous interrupt program) can be executed. Command input or output from a Motion CPU can be
synchronized with the operation cycle of the Motion CPU, which enables high-speed data transfer independent
of scan time. ( Page 166, Section 6.4)
