Function Blocks must have unique names and their I/O must

be assigned. I/O may be constants, variables or rung

connections. Inputs and outputs may be integer or real or

Boolean.

function block:

1. Select the [Selector] tool.

2. Double-click on an existing function block. The Assign

Function Block Symbolic Input/Output dialog box

for that function block appears, as shown in Figure 8.25

on page 103. The Input and Output to which you can

assign Variables are listed in the dialog box.

3. Enter a unique name in the FB Name field. If necessary,

click [List] to see a list of Function Block names in the

current program.

4. Select the value in the Symbolic Input or Symbolic

Output field to which you want to assign a value.

5. Enter a numeric value or variable name in the field at the

bottom of the dialog box,

– or –

click the [Search] button and double-click on a variable

name in the displayed list.

6. Repeat steps 4 and 5 until all Symbolic I/O are assigned.
