III-7.5 SELD (selection of digital variables - function no. 06)
Selection of one of the 4 digital inputs is either by an analog “Select” signal or by the two digital control signals seld1,
seld2. If analog control signal Select is connected, selecting is done using this control signal. If the input is not connec -
ted, selection is by means of the two digital control inputs seld1, seld2.
This function block is cascadable. The select input can be linked with the cas output of another SELD block into a
choice of 8 digital variables.
Inputs/outputs
Digital inputs
d1 Input, is output at z1, when seld1=0 and seld2=0
d2 Input, is output at z1, when seld1=0 and seld2=1
d3 Input, is output at z1, when seld1=1 and seld2=0
d4 Input, is output at z1, when seld1=1 and seld2=1
seld1 1st control signal for variable selection (least significant bit)
seld2 2nd control signal for variable selection (most significant bit)
Analog inputs
Select Dependent on input value, the relevant variable is output at the z1 output C1.4
