5 DETAILS AND SETTING OF FUNCTIONS
5.4 Comparison Output Function
The comparison output function compares any count value set in the
"comparison output setting value" of the buffer memory with the "accumulating
count value" of the buffer memory, and if the "accumulating count value" is equal
to or greater than the "comparison output setting value", turns ON the
accumulating counter comparison flag (X10 to X17).
Set one point of the comparison output setting value for each channel.
The buffer memory addresses related to the setting of the comparison output
function are as follows.

POINT
• If the value outside the range is set to any of the above buffer memory
addresses, a comparison output setting range outside error (error code: 200)
occurs. To clear the error, turn ON the error reset request (Y8 to YF) of the
corresponding channel. After this, set a value within the setting range and then
turn ON the operating condition setting request flag (Y1).
• The settings are reflected on the module by turning ON the operating condition
setting request flag (Y1) after setting the values to the buffer memory.
