The subjects on how Control Modules and Function Blocks are designed for usage
in the graphical editor environments will be handled in this chapter.
The diagram editor is also able to visualize diagrams created in the functional
designer environment but the code cannot be modified in the diagram editor.
General
Protection Attribute on Types
Function Block types, Control Module types, and Diagram types can be divided into
three different categories:
• Function block types/control module types meant to be templates (have suffix
“template”, must be changed by the user to function). These kinds are not
possible to execute without any changes; Protection attribute has to be set to
False.
• Function block types/control module types that could be changed by the user,
these kinds are possible to execute without any changes; Protection attribute
has to be set to False.
• Function block types/control module types that never should be changed or
modified by the user must prevent copying of code; Protection attribute has to
be set to True.
SFC Sequential Flow Chart. In steps and transitions is
ST used.
FD code block This is used in the single graphical code block
that only exist in the first tab of a diagram. Other
code blocks in the diagram may be of any
language.
