Release Notes – october 2022

CDP Framework v4.11

Highlights in the CDP Framework release

• A new Kinematics design module for forward and reverse kinematics supporting Denavit–Hartenberg chain is used to simulate the behaviour of kinematic link chains. This is very useful when designing systems with robotic arms, cranes or other systems with a chain of moving arms. The Kinematics editor (viewer) shows the system graphically
• Automatic test script enhancements, the configurator command-line (CLI) tool test sections, in addition to simple node value assertions, now more complex value test expressions can be used
• New Database Extractor Tool (under the tools folder) allows you to extract a small part of the stored data into a separate file from a potentially very large database file. Very convenient for remote service and maintenance or incident analysis
• Multi-language support and translation; added tools to extract translatable text from a system and merge multi-language texts. Language can be changed by an operator run-time

• EQ and NE Operators now support string type. The Out-argument is changed from T to bool

User interface (UI / HMI) enhancements

• Set any widget property from the control system by adding a dynamic routing property for it
• The stacked widget now supports showing its pages in a slideshow. It can also be configured to reset to first page every time the widget becomes visible
• The slider widget now supports sending values when being moved and returns to the centre point (minValue if fillStartValue has not been changed) when released (joystick mode). Set cdpsend to onMoveAndRelease
• Web UI: CDP application IP and port can now be customized using Javascript
• Possibility to add an overlay over a container that can be enabled from the control system (by a routed value). Useful to overlay a grey colour over a container if the subsystem is offline or a red colour if there is a critical alarm
