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. The I/O address for Soft Bools is

the Soft Bool number.

To read or set a Soft Bool with a logic program variable:

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 (1-256).

7. Click [OK]

Soft Bool Addressing Example

To create a variable named Soft_Bool_178 that sets the value

of soft bool 178, set the options in the Add Program/

Resource Variable dialog box as illustrated below.

1 2 ... 227 228 229 230 231 232 233 234 235 236 237 ... 295 296
