Adding a Project Variable

To add a Project Variable:

1. Click [Add] in the Project Variable dialog box. This

dialog box to opens, as shown in Figure 6.2.

Figure 6.2 Add Project Variable

2. Enter the Variable name. This name must follow the

Variable naming conventions discussed in “Naming

Conventions” on page 49.

3. If you want to create several Variables with similar

names, enter the root name in the Name field and enter

a starting number and ending number in the Increment

field. By this method, multiple Variables are created,

each named with the root name and each appended with

a number.

4. Select the Variable type from the list of types, either:

• BOOL (Boolean)

• INT (Integer)

• LONG (Long integer)

• REAL (Floating Point)

5. Enter the Initial Variable Value. If this field is left

blank, zero is the default value. The Variable holds the

value of zero until the Program changes that value. Initial

value can be used for constant values of function blocks

or constant true/false Variables.
