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
