6. APPLICATION FUNCTIONS
(1) Continuous detection mode
Mark detection data is stored in the mark detection data storage area (one buffer) for every mark detection.
Mark detection data
storage area
(When ON edge detection is enabled)
Mark detection signal
(2) Specified number of detection mode
Only the mark detection data for a set number of detections is stored. When the mark detection signal is
continuously input at a high frequency, positions for a set number of mark detections can be collected.
Example: When the number of detections is 4

The 5th detection
and later are ignored
(When ON edge detection is enabled)
(3) Ring buffer mode
Latched data is stored in a ring buffer for the specified number of detections (number of continuous latch
data storages in parameter settings).
Example: When the number of detections is 4

The 5th detection
replaces the previous
first detection
(When ON edge detection is enabled)
POINT
• Because of the time taken to get latch data by SSCNET communication, the
delay time for the data to reach the user program side is approximately
0.88ms + (control cycle × 2).
(Approximately 2.7ms when control cycle is 0.88ms.)
