Setting of [Input: Digital]
Logic circuit (U01, etc.)

Any of the following functions is selectable as a logic circuit (with general-purpose timer).
Data Function
0 No function assigned
10 Through output +
General-purpose timer
11 (On-delay timer) Turning an input signal ON starts the on-delay timer.
12 (Off-delay timer) Turning an input signal ON turns an output signal ON.
13 (One-shot pulse output) Turning an input signal ON issues a one-shot pulse
14 (Retriggerable timer) Turning an input signal ON issues a one-shot pulse
15 (Pulse train output) If an input signal turns ON, the logic circuit issues ON

Output is always OFF.
Only a general-purpose timer. No logic circuit exists.
(No timer)
When the period specified by the timer has elapsed, an
output signal turns ON.
Turning the input signal OFF turns the output signal
OFF.
Turning the input signal OFF starts the off-delay
timer. When the period specified by the timer has
elapsed, the output signal turns OFF.
whose length is specified by the timer.
whose length is specified by the timer.
If an input signal is turned ON again during the
preceding one-shot pulse length, however, the logic
circuit issues another one-shot pulse.
and OFF pulses (whose lengths are specified by the
timer) alternately and repeatedly. This function is used
to flash a luminescent device.
AND circuit with 2 inputs and 1 output, plus
general-purpose timer.
OR circuit with 2 inputs and 1 output, plus
general-purpose timer.
XOR circuit with 2 inputs and 1 output, plus
general-purpose timer.
Set priority flip-flop with 2 inputs and 1 output, plus
general-purpose timer.
Reset priority flip-flop with 2 inputs and 1 output, plus
general-purpose timer.
Rising edge detector with 1 input and 1 output, plus
general-purpose timer.
This detects the rising edge of an input signal and
outputs the ON signal for 5 ms.
Falling edge detector with 1 input and 1 output, plus
general-purpose timer.
This detects the falling edge of an input signal and
outputs the ON signal for 5 ms.
Rising and falling edges detector with 1 input and 1
output, plus general-purpose timer.
This detects both the falling and rising edges of an
input signal and outputs the ON signal for 5 ms.
