Method and apparatus for seamless state transfer between user interface devices in a mobile control room

摘要

A first user interface device records the state of its user interface on a server. A second user interface requests the state and replicates the user interface. The user interface devices may be mobile devices or one may be a work station and the other a mobile device. The state information may help user collaboration, a single user with multiple devices or device location. The state information may also be transferred directly from one user device to another. The user interface devices may access process data related to operating a process control plant. The user interface devices may respond to location information by displaying information relevant to their location.
