The top/valley hold function is used to hold the top and valley values of the
temperature input value.
Temperature values that fluctuate more than twice the hysteresis value are
monitored, and the top or valley values are held. The top or valley value is
allocated 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 Temperature Data 1. (Refer to details on the comparator function.)

Hold Flag
turns ON (or OFF) in the Master Unit'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 temperature data transmitted to the Master Unit
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 Unit, configure a ladder program which considers the transmis-
sion delay time when the Hold Flag is turned ON, then enables the top/val-
ley hold values after a fixed time interval.

time (the setting range is 1 to 65,535 ms).
Flag is set to be ON, both flags will turn OFF simultaneously.
