5.7 Programming a Block Call in Statement List
All the work you have done programming a function block is of no use unless you
call this block in OB1. A data block is used for each function block call, and in this
way, you can control both engines.
The SIMATIC Manager is open with
your "Getting Started" project.
Navigate to the Blocks folder and
open OB1.
Select network 3 and then insert
network 4 in the LAD/STL/FBD
program window.
Type CALL "Engine", "Petrol" in the
code section and then press Enter.
All the parameters of the function block
"Petrol" are displayed.
Position the cursor after the equals
sign of Switch_On and press the right
mouse button.
Click on Insert Symbol in the shortcut
menu via a right-click on mouse
button. A pull-down list is displayed.
