13.13.4 SFC Element Properties
The properties of a SFC element can be viewed and edited in the "Element properties"
window. This window can be opened via command 'Element Properties', which by
default is part of the 'View' menu.
It depends on the currently selected element which properties are displayed The
properties are grouped and the particular group sections can be opened or closed by
using the plus- resp. minus signs.
Notice that in the 'View' tab of the SFC Editor options you can configure whether the
particular types of properties should be displayed next to an element in the SFC chart.
See in the following all possible properties:
Common:
Name Element name, by default "<element><running number>" , for example step name
"Step0", "Step1", branch name "branch0" etc.
Comment Element comment, text string, for example "Reset the counter". Linebreaks can be
inserted via <Ctrl>+<Enter>.
Symbol For each SFC element implicitly a flag is created, named like the element.
Here you can specify whether this flag variable should be exported to the symbol
configuration and how the symbol then should be accessible in the PLC.
Perform a double-click on the value field, resp. select the value field and use the
space-key in order to open a selection list from which you can choose one of the
following access options:
None: The symbol will be exported to the symbol configuration, but it won't not be
accessible in the PLC:
Read: The symbol will be exported to the symbol configuration and it will be
readable in the PLC.
Write: The symbol will be exported to the symbol configuration and it will be
written in the PLC.
Read/Write: Combination of Read and Write.
By default nothing is entered here, which means, that the symbol not at all is
exported to the symbol configuration.
