Maximum Value/Minimum Value Hold Function
For each channel, this function stores the maximum value and the minimum value of digital operation values into the
following remote buffer memory.
If averaging processing is specified, the values are updated per averaging process cycle. Otherwise they are updated
per sampling cycle.
(1) Resetting maximum and minimum values
• Turning on and off Maximum value/minimum value reset request (RY1D) of the main A/D converter module
allows the maximum and minimum values of the main A/D converter module to be updated to the current
values.
• Turning on and off Maximum value/minimum value reset request (RY2D) of the extension A/D converter
module allows the maximum and minimum values of the extension A/D converter module to be updated to
the current values.
• Turning on and off Initial data setting request flag (RY9) allows the maximum and minimum values of both
the main A/D converter module and the extension A/D converter module to be updated to the current values.
(2) Target of the maximum and minimum values
The maximum and minimum values of digital operation values are stored into the remote buffer memory.
