Input 3
Comparative input port 2, with
0.0~10.0, I1~IC to be selected.
Output Q
Conditions permitted, output Q
is 1 and the following outputs are
at option: Q1~Q8, M00~M126.
Notes:
Only FAB2s like AF-10MR-D2, AF-10MT-D2, AF-10MT-GD2, AF-20MR-D2,
AF-20MT-D2 and AF-20MT-GD2 have this function, which is used in the input
function block for analog quantity.
Instructions for the comparison function of analog quantity:
The comparison function of AN block is the comparison between input 1 and
input 3. For instance, when you select input 2 as “>”, it means that when input
1>input 3, Q will be 1 while when input1<input3, Q will be 0
Example 1:
Input 1 =I1 Input 3=5 Input 2= “>”,
Q=Q1 If I1>5.0V,
then Q1will be ON If I1<5.0V, then Q1 will be OFF.
Example 2:
Input 1=I1 Input3=I2 Input 2= “<“,
Output=Q2 If I1<I2,
then Q2 will be ON If I1>I2, then Q2 will be OFF.
