6.5 Holding Max./Min. Values
 Overview of Functions
This function maintains the maximum and minimum values of acquired data. When the
maximum and minimum value hold settings are valid, the maximum and minimum digital
conversion values will be maintained and stored in the following unit memories.
• If the function has not been enabled with the configuration settings, the function will not
work with the hold execution relay turned ON.
• When the hold execution relay is turned ON, the values at that time will be preset as
maximum and minimum values in the unit memories.
• The maximum and minimum values will be stored in the unit memories even if the hold
execution relay is turned OFF or the unit is set into PROG. mode.
• The maximum and minimum values are held on a channel-by-channel basis.
