5.2 Types of Count Operations

5.2.1 Types and Features of Count Operations

 Types of count operations and input signals
Operation
Type
Simple count Performs the count operation regardless of external control
operation input signals.
Performs the reset operation according to the change in the
Reset count
z-phase input signal (rising, trailing, positive logic or
operation
negative logic).
Performs the preset operation according to the change in
Preset count
the z-phase input signal (rising, trailing, positive logic or
operation
negative logic).
Enable count Performs the count operation while the control signal
operation allocated to the enable input is effective.
Performs the count operation while the control signal
Enable reset
allocated to the enable input is effective. Resets the count
count
value at the timing at which the counter becomes enabled
operation
by the control signal allocated to the enable input.
Performs the count operation while the control signal
Enable preset
allocated to the enable input is effective. Presets the count
count
value at the timing at which the counter becomes enabled
operation
by the control signal allocated to the enable input.
(Note 1): In any of these cases, resetting or presetting values can be performed by output relays (Y).
(Note 2): If the control signals are used in the above operations, the same signals cannot be used for the capture
function or sampling chapture function.
(Note 3) To enable the count input when selecting the simple count operation, reset count operation or preset count
operation, it is necessary to turn on the count enable request signal (Y1) in user programs.
