Peak/Bottom Hold
Peak/bottom hold is used to hold the maximum (peak) value or minimum (bot-
tom) value of the analog input value. When the Hold Flag (output) allocated in
the Output Area turns ON, the hold function starts, searching for the peak or
bottom value until the Hold Flag turns OFF. (The peak/bottom value is
refreshed when the Hold Flag turns OFF.) The comparator function can be
used to compare the peak or bottom values allocated as analog data. (Refer
to details on the comparator function.)
■
Example of Bottom Hold
Note
A delay in network transmission time will occur from the time the Hold Flag
turns ON (or OFF) in the Master’s ladder program until notification of the flag’s
status is actually sent to the Unit. Therefore, even when the Hold Flag is ON,
the first analog data transmitted to the Master when the CPU Unit power is
ON
OFF
