Remark
･ Normally, the displayed free time value is the specified main scan cycle (Mt) minus
the main scan program execution time (Pt): (Mt-Pt) ≥ 0.
･ If the main scan program execution is extended or programs with higher priority
are executed frequently, the actual main scan execution cycle (Rt) may exceed the
specified main scan cycle (Mt) (this state is called "scan congestion"). In this case,
the displayed free time value displayed is the specified main scan cycle (Mt) minus
the actual main scan execution cycle (Rt): (Mt-Rt) ≤ 0.
