Precautions When Using Control Instructions
● The condition of the previous execution and the condition of the current execution are
compared, and the leading edge detection instruction is executed only if the previous
condition was OFF and the current condition is ON. They are not executed in any other
circumstance.
● Therefore, take care that, when a leading edge detection instruction is used in combination
with an instruction which changes the order of instruction execution, such as MC - MCE or
JP - LBL, operations may change as follows depending on input timing.
