instruction for falling edge pulse
When writing is completed during RUN for a circuit including an instruction for falling edge pulse (LDF,
ANDF, or ORF instruction), the instruction for falling edge pulse is not executed regardless of the ON/OFF
status of the target device of the instruction for falling edge pulse.
When writing is completed during RUN for a circuit including an instruction for falling edge pulse (PLF
instruction), the instruction for falling edge pulse is not executed regardless of the ON/OFF status of the
operation condition device.
It is necessary to set to ON the target device or operation condition device once and then set it to OFF to
execute the instruction for falling edge pulse.

Instruction for rising edge pulse
When writing is completed during RUN for a circuit including an instruction for rising edge pulse, the
instruction for rising edge pulse is executed if a target device of the instruction for rising edge pulse or the
operation condition device is ON.
