25 HIGH-SPEED INPUT/OUTPUT FUNCTION
25.3 Pulse Width Measurement Function
Rising edge ring counter value
The ring counter value when the rising edge is detected is stored.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
■Update timing
Devices are updated by the END instruction.
■Clear timing
The timing when the device is cleared is as follows.
•Power OFFON
• Reset
•STOP/PAUSERUN
Falling edge ring counter value
The ring counter value when the falling edge is detected is stored.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
■Update timing, clear timing
Same as the rising edge ring counter value (Page 310 Rising edge ring counter value)
Pulse width latest value
The latest value of the pulse width is stored.
• When logic switching is set to positive logic, the difference from the rising edge up to the falling edge.
• When logic switching is set to negative logic, the difference from the falling edge up to the rising edge.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
■Update timing, clear timing
Same as the rising edge ring counter value (Page 310 Rising edge ring counter value)
