(2) Application of input signal
There are two kinds of applications of the input and mark detection for the
Q170MSCPU's internal I/F.
The same signal can be used simultaneously by the input and mark detection.
I/O setting Input signal Mark detection
Used Usable as the real input device (PX)
Usable as the real input device (PX) or
mark detection signal (DI)
Unused Unusable Usable as the mark detection signal (DI)
(3) High-speed reading of specified data
This function is used to store the specified positioning data in the specified device
(D, W, U
\G). The signal from input module controlled in the Motion CPU area is
used as a trigger.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion Controller Programming
Manual (COMMON)" for the high-speed reading of specified data.
(a) Modules and signals to be used

(Note-1): Only one PLC input module can be used.
(Note-2): Either of the input signal of internal I/F (DI) and PLC input module can be used.
(4) Mark detection function
Any motion control data and all device data can be latched at the input timing of
the mark detection signal. Also, data within a specific range can be latched by
specifying the data detection range.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion Controller Programming
Manual (COMMON)" for the mark detection function.
(a) Mark detection signal
Set the input signal for mark detection.
1) Module input signal
