(21)CH  Maximum value, CH  Minimum value
The maximum and minimum values of converted digital operation value are stored as signed 16-bit binary.
See below for reset.
• Turning on and off Maximum value/minimum value reset request (RY1D) of the main A/D converter module
results in CH  Maximum value and CH  Minimum value of the main A/D converter module being updated
to the current value.
• Turning on and off Maximum value/minimum value reset request (RY2D) of the extension A/D converter
module results in CH  Maximum value and CH  Minimum value of the extension A/D converter module
being updated to the current value.
• Turning on and off Initial data setting request flag (RY9) results in CH  Maximum value and CH  Minimum
value of both the main A/D converter module and the extension A/D converter module being updated to the
current value.
(a) Remote buffer memory address
The remote buffer memory addresses of this area are as follows:
●
With the averaging processing specified, the maximum and minimum values are updated per averaging process cycle;
otherwise, updated per sampling cycle.
● With the following functions used, values computed by each function are stored in the maximum value and the minimum
value:
• Digital clipping function
• Scaling function
• Shift function
• Difference conversion function
(22)Extension module identification code
The identification code for a connected extension module is stored.
If the extension A/D converter module is connected, 2111H is stored.
For the identification code for extension modules other than the extension A/D converter module, refer to the
following:
