9 CREATING A HARDWARE LOGIC
9.2 Multi Function Counter Block
Output
The following table shows the output of the comparison block.
■When "Condition" is set to "Coincidence"
*1 The setting of "Compare Mode" is reflected to .
A value other than 0 is recommended for the compare value. When the compare value is set to 0, the status of
the Output terminal turns to High soon after the hardware logic control starts because the count value soon
after the hardware logic control starts is 0.
■When "Condition" is set to "Range"
Set the comparison value so that "Compare Value A" is equal to or smaller than "Compare Value B". When
"Compare Value A > Compare Value B" is set, values are output as follows.
• Output of "Value A <= Input <= Value B" is always Low.
• Output of "Input < Value A, Value B < Input" is always High.
Variable name Data type Linkable block Output value Description
Input Value A
*1
Bit • Set/reset
• Event output
0, 1 Outputs the comparison result between "Count Value" and
"Compare Value A".
Input Value B
*1
Bit • Set/reset
• Event output
0, 1 Outputs the comparison result between "Count Value" and
"Compare Value B".
Variable name Data type Linkable block Output value Description
Value A <= Input <=
Value B
Bit • Set/reset
• Event output
0, 1 Compares "Count Value" with the range using "Compare Value
A" and "Compare Value B" and outputs the result.
• Within range: High
• Out of range: Low
Input < Value A, Value B
< Input
Bit • Set/reset
• Event output
0, 1 Compares "Count Value" with the range using "Compare Value
A" and "Compare Value B" and outputs the result.
• Within range: Low
• Out of range: High
