Operation and Precautions at Run Start Time
● The leading edge detection instruction is not executed when the mode has been switched to
the RUN mode, or when the power supply is booted in the RUN mode, and if the trigger
(execution condition) is already ON.

● If you need to execute an instruction when the trigger (execution condition) is ON prior to
switching to the RUN mode, make a program as below using SR14 (special internal relay).
(SR14 is a special internal relay which is OFF during the first scan and turns ON at the
second scan onwards.)
Example 1) DF (leading edge differential) instruction
X100
Y100

X100
Y100
DF
SR14
Add SR14
X100
Y100
RUN
(Power ON)
Differential output is obtained because the input condition of the
differential instruction changes from OFF to ON in the second scan, even
if X100 has been set ON earlier.
