Techniques for configuring and presenting multiple languages at a user interface executing in an operating environment of a process plant include configuring, in a configuration environment, a multi-language interface object to indicate a plurality of languages that may be presented at the user interface. The multi-language interface object includes a parameter whose value is changeable, within the operating environment, to indicate a desired language that is to be presented on the user interface. A configuration of the graphical display view that references the configured multi-language interface object is downloaded into the operating environment. Thus, during runtime, changes in the language utilized at the user interface are implemented without any additional downloads from or communications with the configuration environment. Independently selectable user controls may be provided to independently control the language utilized by fixtures of the user interface and the language in which graphical display view content is presented.

Techniques for presenting historized process parameter values in a process plant include presenting, via a user interface of an operator application, indications of process control elements in a first display region within a layout of a display view. Each of the process control elements is associated with one or more process parameters. The operator application also presents a trend display view in a second display region within the layout of the display view. The trend display view includes sets of historized process parameter values for process parameters presented in the first display region. For example, the trend display view in the second display region is linked to the display view in the first display region. In this manner, the trend display view presents charts or other graphical depictions of historized process parameter values for process parameters included in the first display region.

Techniques for configuring layouts and display view hierarchies and presenting display views in an operating environment of a process plant according to the layouts and display view hierarchies include providing graphical user controls at a graphical display configuration application for defining a layout. The layouts indicate a manner in which divide one or several display screens into one or several display regions, where each display region presents a display view that includes indications of process control elements. The graphical display configuration application also includes graphical user controls for defining a display view hierarchy of the display views by assigning levels of detail to the display views and designating some of the display views as subviews of other display views. An operator application obtains the defined layout and display view hierarchy and presents the display views at an operator workstation according to the obtained layout and/or display view hierarchy.

Systems and methods for presenting a watch area display view in a process plant are provided. Indications of process control display elements may be presented via a user interface of a computing device executing an operator application in an operating environment of a process plant. The process control display elements may be displayed in a first display region in a display view, with each of the process control display elements corresponding to process parameters. Simultaneously with the first display region, a second display region (not occluding any process control display elements) may be presented in the display view. An indication that a user has selected one of the process control display elements in the first display region for display in the second display region may be received. The one or more process parameters corresponding to the selected process control display element may be displayed in the second display region.

Configuring graphical display views to be presented, at a user interface of an operating environment of a process plant, using multiple graphical display themes includes configuring a display theme object to indicate a plurality of themes via which the display view is able to be presented at the user interface. The display theme object includes a parameter whose value is changeable, within the operating environment, to indicate a desired theme that is to be utilized, and the display theme object is downloaded from the configuration environment into the operating environment. Thus, during runtime, changing the theme via which the graphical display view is presented is achieved without any additional downloads from or communications with the configuration environment. User controls may be provided to an operator to select different themes, and/or to override various visual aspects of themes to achieve optimum visibility. Themes may be automatically changed based on sensed conditions.

A long-haul process control plant includes a process control system which controls industrial processes running within the plant, and a safety instrumented system, servicing the process control system, which detects safety-related problems within the plant and communicates safety messages within and between portions of the process plant, e.g., to effect a trip or other mitigating action. To transmit safety messages between remotely located portions of the process plant via a low-bandwidth long-haul link, a safety data concentrator combines individual safety messages generated by the safety logic solvers disposed at one portion of the plant into a concentrated safety message, and transmits the concentrated safety message to a safety data de-concentrator in the remote portion of the plant. The safety data de-concentrator recovers the individual safety messages from the concentrated safety message and communicates the recovered safety messages to recipient safety logic solvers disposed at the remote portion of the plant.

A method for controlling a packaging machine in which at least two operating states of the packaging machine are defined and independent from one another. At least one of a plurality of defined process sequences is allocated to each of the operating states and at least one actuator of the packaging machine is actuated by a process sequence, in order to carry out at least one action. Improved control and maintenance of the machine is made possible by an authorisation for access to an actuator being exclusively and specifically allocated to only one process sequence depending on the operating state.
