The setting values of CH  Ring counter upper limit value (RWw12 to RWw13, RWw2A to RWw2B) and CH  Ring
counter lower limit value (RWw10 to RWw11, RWw28 to RWw29) can be reflected by turning off then on Initial data
processing completion flag (RY8) or by turning off then on Initial data setting request flag (RY9). In that case, however,
monitoring data such as CH
 Present value (RWr10 to RWr11, RWr28 to RWr29) is cleared. For ordinary use, reflect the
setting values by turning off then on CH  Count enable command (RY24, RY3C).
●
When CH  Count enable command (RY24, RY3C) is on, the stored value does not change even if a value is written to
CH  Ring counter lower limit value (RWw10 to RWw11, RWw28 to RWw29) and CH  Ring counter upper limit value
(RWw12 to RWw13, RWw2A to RWw2B).
Turn off CH
 Count enable command (RY24, RY3C) before changing CH  Ring counter upper limit value (RWw12 to
RWw13, RWw2A to RWw2B) and CH  Ring counter lower limit value (RWw10 to RWw11, RWw28 to RWw29). The OFF
time must be longer than

● Always turn off CH  Count enable command (RY24, RY3C) before changing the counting range by the preset/replace
function to prevent a miscount.
