Soft_Input
A logic program can generate an analog input to a closed-loop
control channel. To do so, output a value to one of the Soft
Input registers and enable the soft input for use on the
channel.
To set a Soft Input with a logic program variable:
1. Open the Add Program/Resource Variable dialog box.
2. Enter a unique variable Name.
3. Select INT from the Type list.
4. Select Output by clicking the check box.
5. Select Soft_Input from the IO Driver list.
6. Select WORD as the IO Size.
7. In the IO Physical Address field enter the Soft Input num-
ber (1-9).
8. Click [OK].
Soft Input Addressing Example
To create a variable named PV_From_Logic_1 that sets the
value of the first soft input, set the options in the Add
Program/Resource Variable dialog box as illustrated below.
