Period latest value
The latest value of the period is stored.
• When logic switching is set to positive logic, the difference from the previous rising edge up to the latest
rising edge.
• When logic switching is set to negative logic, the difference from the previous falling edge up to the latest
falling 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 271 Rising edge ring counter value)
Period maximum value
The maximum value of the period is stored.
• When logic switching is set to positive logic, the difference from rising edge to rising edge.
• When logic switching is set to negative logic, the difference from falling edge to falling edge.
• The maximum value of the period can be changed only by the HCMOV/DHCMOV instruction.
