DMS 4.1 EN 03/2011 TD29 59
New concerning operators and variables
• New scope operators, extended name spaces
• Function Pointers replacing the INSTANCE_OF operator
• Init method replacing the INI operator
• Exit method
• Output variables in function and method calls
• VAR_TEMP, VAR_STAT
• Arbitrary expressions for variable initialization
• Assignment as expression
• Index access with pointers and strings
• Extensible functions (variable number of parameters) - not yet implemented
New Visualization concept
• The Visualization Editor per default is working in combination with a Toolbox and a
Visual Element Properties Editor.
• Parts of the visualization functionality are realized according to IEC 61131 and thus
provided via libraries.
• An internal runtime system executes the main visualization functions.
• Visual elements are provided via libraries (Visual Element Repository).
• Textlists and image pools are used for managing texts and images.
New User Management and Access Rights concept
• User accounts, user groups, group-specific rights for access and actions on
particular objects
New in editors
• ST-Editor: Folding, Linebreak, Autocomplete, Inline Monitoring, Inline set/reset-
assignment
• FBD, LD and IL are reversible and programmable in a combined editor
• IL editor is a table editor
• LD/FBD/IL editor: main output in boxes with multiple outputs can be changed
• LD/FBD/IL editor: no automatic update of box parameters
• LD/FBD/IL editor: branches and "networks within networks"
• SFC editor: only one step type, macros, multiple selection of independent elements,
no syntactic check during editing, automatic declaration of flag variables
Library versions
• Multiple versions can be used in the same project, unique access to library modules
by specifying the namespace
• Installation in repositories, automatic update, debugging
and more....
• Configurable menus, toolbar and keyboard usage
• Customer-specific components might be plugged in
