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.

1 2 ... 213 214 215 216 217 218 219 220 221 222 223 ... 295 296
