3. Analog comparator
Symbol Description
Analog comparison mode (1-3)
Selection of the input comparison
value
(AS1~AS4,MD1~MD4,T1~T8,C1~C8,V
1~V7)
Setting reference comparison value
(up limit)
Setting reference comparison value
(Upper Limit)
(AS1~AS4,MD1~MD4,T1~T8,C1~C8,V
1~V7,count)
Setting reference comparison value
(Lower Limit)
(AS1~AS4,MD1~MD4,T1~T8,C1~C8,V
1~V7,count)
Output terminals of analog
comparator(G1~G4)
Analog Comparison Mode (1-3)
(1) Analog comparator mode 1 ( ≤ , ON)
(G1)
(T1)
The target value of G1 is
determined by the
present value of T1

4.0
G1
T1
Input under the Function Program Mode
Input under the Ladder Program Mode
0.3
Because present input
Value(0.3)<lower
limit(4.0),so G1is ON
Analog comparision mode is model
Lower limit is 4.0
The present value of Timer 1 is 0.3
The number of Analog
comparision:G1~G8
(2) Analog comparator mode 2 ( ≥ , ON)
(3)
Analog comparator mode 3 ( ≤ ≤ , ON)
