III-7.11 SELV2 ( cascadable selection of variables (No. 39))
Dependent of input Select,, one of the four inputs x1...x4 is connected with output y1. Unused inputs are interpreted as
0. Output
Casc = input Select -3.
The function can be cascaded as shown in the example given below. Dependent of input signal Select at the 1st
SELV1, the corresponding variable is output at Y1 of the 2nd SELV2.
SELV1 y 1output 2nd SELV1
Select< 1,5 x1 of 1st SELV1
1,5 < Select < 2,5 x2 of 1st SELV1
2,5 < Select <3,5 x3 of 1st SELV1
3,5 < Select < 4,5 x4 of 1st SELV1
4,5 < Select < 5,5 x2 of 2nd SELV1
5,5 < Select < 6,5 x3 of 2nd SELV1
< 6,5 x4 of 2nd SELV1
Inputs/outputs
Analog inputs
x1
Input is output at y1 with Select< 1,5.
x2
Input is output at y1 with 1,5 < Select < 2,5.
x3 Input is output at y1 with 2,5 < Select < 3,5.
x4
Input is output at y1 with Select < 3,5.
Select
Dependent of input value, the relevant variable is output at y1.
Analog outputs
