(b) Enabling synchronous processing with a motion control
An interrupt program which is synchronized with the operation cycle of a motion controller (multiple CPU syn-
chronous 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.

The synchronous processing with the Motion CPU is available when the following CPU modules are used.
• Universal model QCPU (except Q00UCPU, Q01UCPU, Q02UCPU )
• Motion CPU (Q172DCPU, Q173DCPU )
