Because in this example the SV for CNT 01 is 100 and the SV for CNT 02 is
200, the completion flag for CNT 02 turns ON when 100 x 200 or 20,000 OFF
to ON changes have been counted in 0001. This would result in 0203 being
turned ON.
CNT can be used in sequence as many times as required to produce count-
ers capable of counting down even higher values.
CNT can be used to create extended timers in two ways: by combining TIM
with CNT and by counting SR area clock pulse bits.
In the following example, CNT 02 counts the number of times TIM 01
reaches zero from its SV. The completion flag for TIM 01 is used to reset TIM
01 so that is runs continuously and CNT 02 counts the number of times the
completion flag for TIM 01 goes ON (CNT 02 would be executed once each
time between when the completion flag for TIM 01 goes ON and TIM 01 is
reset by its completion flag). TIM 01 is also reset by the completion flag for
CNT 02 so that the extended timer would not start again until CNT 02 was
reset by 0001, which serves as the reset for the entire extended timer.
As the SV for TIM 01 is 5.0 seconds and the SV for CNT 02 is 100, the com-
pletion flag for CNT 02 turns ON when 5 seconds x 100 times, or 8 minutes
and 20 seconds have expired. This would result in 0201 being turned ON.
In the following example, CNT 01 counts the number of times the 1-second
clock pulse bit (1902) goes from OFF to ON. Here again, 0000 is used to
control when CNT is operating.
