Abstract: A data structure comprising a link to a set of binding points enabling connection to a building control system and a model of said automation control system is disclosed. The model comprises a plurality of virtual components arranged in a structure associated with functions of said automation control system. Each virtual component is assigned a set of properties for viewing a representation of said virtual component. Each set of properties comprises a first sub-set of properties being linked to said binding points such that actual values for corresponding actual component are provided to said virtual component, and a second sub-set of properties for how said representation of said virtual component is to be viewed with respect to said actual values. Each property of said second sub-set of properties selectably comprises a locally or a globally assigned parameter. An automation system management tool utilising the data structure, and an automation control system comprising the tool are disclosed.
