■ Single-phase high-speed counter
 The single-phase high-speed counter has three operation modes, the adding counter, the up/down selection reversible counter, and the dual-
pulse reversible counter.
 The up/down selection reversible counter and the dual-pulse reversible counter which can count in both directions are supported.
 This counter support 100 kHz (pulse width ≥ 5 μs) maximum pulse input and is capable of counting in a range from 0 to 4,294,967,295 (32 bits).
 When the current value and preset value match or an overflow or underflow occurs, a comparison output turns on or an interrupt program is
executed.
 This counter support resetting the current value by special internal relay reset input and reset input. When the reset input is turned on or
when the current value reset is executed, the current value becomes the reset value specified by special data registers. For details on the
reset input, see "Reset input" on page 5-28.
*1 The Plus 16-I/O type supports only reset input by special internal relay.
The Plus 32-I/O type can use I13 as an external reset input.
■ Two-phase high-speed counter
Group 1 to 2, group 3 to 4, group 5 to 6 two-phase high-speed counter
 The two-phase high-speed counter counts with the phase difference between A-phase and B-phase pulse inputs.
 These groups support 50 kHz maximum pulse input and are capable of counting in a range from 0 to 4,294,967,295 (32 bits).
 Even higher speed counting is possible by specifying 2-edge count or 4-edge count.
 When the current value and preset value match or an overflow or underflow occurs, a comparison output turns on or an interrupt program is
executed.
 These groups support resetting the current value by special internal relay reset input and external reset input (Z-phase). When the reset
input is turned on or the current value reset is executed, the current value becomes the reset value specified by special data registers.
*1 The Plus 16-I/O type supports only reset input by special internal relay.
The Plus 32-I/O type can use I13 as an external reset input.
