Soft_Bool
A Soft Bool can be used in logic programs by creating a variable in
the logic program that points to the Soft Bool as if it were physical
I/O. This allows the logic program to examine and set values of Soft
Bools. For example, an HMI program could allow a user to set a
software switch that is read by and affects the operation of a logic
Program. The I/O address for Soft Bools is the Soft Bool number.
To associate a variable with a Soft Bool:
1. Open the Add Program/Resource Variable dialog box.
2. Enter a unique variable Name.
3. Select BOOL from the Type list.
4. Select Input or Output by clicking the corresponding check
box.
5. Select Soft_Bool from the IO Driver list.
6. In the IO Physical Address field, enter the Soft Bool num-
ber (1-1000).
7. Click [OK].
Soft Bool Addressing Example
To create a variable named Soft_Bool_278 that sets the value of Soft
Bool 278, set the options in the Add Program/Resource
Variable dialog box as illustrated below.
