DAD achieves a step change in productivity by improving information and work management for power, control and communication systems.


Information is gathered into software objects on a 1:1 relationship for each system part. The software object can hold but is not limited to:


  • Data organised by attributes
  • Supplementary files such as vendor data, photos, test sheets, etc.
  • Terminals or ports where connections are made
  • Complete data object history of changes.


The objects are assembled in the SIM (System Information Model) arranged like the real system equivalent in two core categories:


  • Location – where objects are shown in their relative positions
  • Type – where objects are shown by generic or specific model types.


Systems have physical connections (wires, cables etc.). Each cable like each object has a software object equivalent in DAD. DAD connects the objects, representing the cables, wires, fibres and signals as data in the SIM.


System functions depend on hardware and application software. The SIM describes both using:


  • Objects in a base layer define the hardware
  • Objects in other layers define the application software
  • Objects on different layers are linked to define functions.
