Example of Valley Hold
Note
1. 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 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.
2. The time that the Top/Valley Detection Timing Flags are ON can be adjust-
ed by setting the one-shot time. Use the Setting Tool to set the one-shot
time (the setting range is 1 to 65535 ms).
3. If the Hold Flag turns OFF during the time the Top/Valley Detection Timing
Flag is set to be ON, both flags will turn OFF simultaneously.
