Parameter
The following table shows the parameters of the comparison block.
*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.
Ex.
The following table shows examples of comparison with "Count Value" of the counter timer block when "Compare Value" is set
to 1000 and "Compare Mode" is set to >.

Variable name Data type Valid range Setting range Description
User Address Word  1000 to 1099 Only even addresses can be assigned to the
parameters of two words (32 bits).
"Count Value" Comparison result
900 The comparison fails because "Count Value" is equal to or smaller than
"Compare Value".
Thus, the "Output" terminal status is turned to Low.
1100 The comparison succeeds because "Count Value" is larger than "Compare
Value".
Thus, the "Output" terminal status is turned to High.
