Visualization of information for maintenance
In order to recognize the conditions of individual devices or components unequivocally, a uniform symbol represen- tation has been implemented.
There are symbols for the device status itself and also for the importance of a maintenance request. In addition, the status of a maintenance measure is displayed. The conditions of all devices and equipment of the automation technology and of the plant components are indicated by these standardized symbols.

Uniform symbols for the conditions of components and devices
Besides the uniform display of symbols, a significant detail for the overview is a hierarchical structuring of information in which the maintenance engineer also has access to all requi- red details of the components and devices, based on an over- view display (plant view).
The overview display uses the standardized symbols to visua- lize the condition of a component itself and also provides coll- ective information on the conditions of all devices in the sub- ordinate hierarchies.
The collective condition message shows the OK condition or the seriousness of a possible problem in red, yellow, or green, as per a traffic light. A button can be used to access all subor- dinate hierarchy levels
Further views of the maintenance information are available in addition so that the maintenance engineer has a complete overview of all current information of the asset relevant to maintenance. This permits assessment of the plant status at a glance.

The information is consistently structured and hierarchically organized. The quantity of information displayed on each in- dividual screen always remains manageable for the mainte- nance engineer, who nevertheless has easy access at any time to the complete information.
