Naming and Assigning Variables to Function
Blocks
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.
To assign symbolic Variable names or preset values to a
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.
