a) If the time average value is not specified within 4 ~ 16000, RUN LED blinks
at an interval of 1s. In order to set RUN LED to ON status, set the time
average value within 4 ~ 16000. Then change PLC CPU mode from STOP to
RUN. Ensure to clear the request flag (UXY.11.0) from online modification
(in RUN mode).
b) If an error occurs in set value of time average, the default value of 2 is saved.
3. Any remainder produced, when set time is divided by (number of channels used X
conversion speed), is ignored. Thus, the average processing frequency is the
quotient of [(setting time) ÷ (number of channels used x conversion speed)].
Example:
If the number of channels used is 5 and setting time is 151ms
151ms ÷ (5 X 0.25ms) = 120times ...... Remainder of 8 is ignored 120 times
Count average processing
1. Setting range: 2 ~ 64000 (times)
2. The time required for average value (frequency average) to be saved on memory,
depends on the number of channels used.
Process time = set frequency X number of channels used X conversion speed
a) If set value of count average is not specified within 2 ~ 64000, RUN LED
blinks at an interval of 1s. In order to set RUN LED to On status, reset the set
value of frequency average within 2 ~ 64000. Then change PLC CPU mode
from STOP to RUN. Ensure to clear the request flag of error clear (UXY.11.0)
from online modification (in RUN mode).
b) If any error occurs in the set value of frequency average, the default value 2 is
saved.
Example:
If the number of channels used is 4, and average processing frequency is 50.
50 X 4 X (0.25ms) = 50ms
