Data Function Description

Hold + General-purpose timer Hold function of previous values of 2 inputs and 1
output, plus general-purpose timer.
If the hold control signal is OFF, the logic circuit
outputs input signals; if it is ON, the logic circuit
retains the previous values of input signals.
110 Increment counter Increment counter with reset input.
By the rising edge of an input signal, the logic circuit
increments the counter value by one. When the
counter value reaches the target one, the output signal
turns ON.
Turning the reset signal ON resets the counter to zero.
120 Decrement counter Decrement counter with reset input.
By the rising edge of an input signal, the logic circuit
decrements the counter value by one. When the
counter value reaches zero, the output signal turns
ON.
Turning the reset signal ON resets the counter to the
initial value.
130 Timer with reset input Timer output with reset input.
If an input signal turns ON, the output signal turns ON
and the timer starts. When the period specified by the
timer has elapsed, the output signal turns OFF,
regardless of the input signal state.
Turning the reset signal ON resets the current timer
value to zero and turns the output OFF.
