Compare Mode B
Compare Value A Word
Compare Value B
*1 The valid range is determined by the type of the multi function counter block arranged in the hardware logic outline window.
The following table shows "User Address" used for the parameters.

Comparison result
The comparison fails because "Count Value" is equal to or smaller than
"Compare Value".
Thus, the "Output" terminal status is turned to Low.
The comparison succeeds because "Count Value" is larger than "Compare
Value".
Thus, the "Output" terminal status is turned to High.
Default value Description
Coincidence Specify a comparison method.
• Coincidence
• Range
(Blank) Select a mode for comparing the count value and
the compare value.
When "Condition" is set to "Range", this setting is
disabled.
0 Set the value to be compared with the count value.
Setting range Description
1000 to 1099 Only even addresses can be assigned to the
parameters of two words (32 bits).
