Note
■ Example of Valley Hold
Top/valley hold is used to hold the top and valley values of the analog input
value.
Analog values that fluctuate more than twice the hysteresis value are moni-
tored, and the top or valley values are held. The top or valley value is allo-
cated along with the Top/Valley Detection Timing Flags, which can be used to
check the hold timing.
When the Hold Flag (output) allocated in the OUT Area turns ON, the hold
function starts, refreshing the top or valley value until the Hold Flag turns OFF.
(The last value is held when the Hold Flag turns OFF, but the next time the
Hold Flag turns ON, the hold value is initialized as soon as a top or valley
occurs.) The comparator can be used to compare the top or valley value allo-
cated as analog data. (Refer to details on the comparator function.)

turns ON (or OFF) in the Master’s ladder program until notification of the
flag’s status is actually sent to the Slave. Therefore, even when the Hold
Flag is ON, the first analog data transmitted to the Master when the CPU
Unit power is turned ON may be the data from when the Hold Flag was
OFF. To collect top/valley hold data using the Hold Flag at the Master, con-
figure a ladder program which considers the transmission delay time when
the Hold Flag is turned ON, then enables the top/valley hold values after a
fixed time interval.

time (the setting range is 1 to 65535 ms).
