• Written in Java → operation system independent
• Based on Equinox an OSGi implementation
• OSGi is an open standard organization „Open Services
Gateway initiative‟
• Plug-in technology
• Using SWT/JFace for UI
• Provides a Rich Client Platform (RCP) for general
applications
• Add new functionality by extension points
• Many helpful features (Drag and Drop, Help System, Update
site, Language support, …)

• All remote features are located in separated plug-ins → CSS can
easily be built with or without remote management
• CSS Core provides common remote commands (e.g. update plug-
in, write preference, …)
• Each plug-in is able to provide its own remote
commands

SDS Properties and Dynamisation
Dynamisation of a property means that the property
depends on a value of a process variable• Properties are ordered in categories
• Dynamisation is indicated by an additional icon
• Every widget property can be dynamic
• Widget behaviors simplifies the setup
• Aliases can be used for PV names

SDS Behaviors
Behaviors defines a site specific default set up for widgets
• A Behavior is related to one widget
• Widgets can have many behaviors
• Behaviors set default values for properties
• Properties can be hidden from the user
• For e.g. new alarm colors just the behavior has to be
changed
• Behaviors are implemented as java classes
