Soft_Input

A logic program can generate an analog input to a closed-loop

registers and select that register as the PV Source for the channel.

To associate a variable with a soft input:

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 from the IO Size list.

7.

In the IO Physical Address field, enter the Soft Input num-
ber (1-50).

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.
