Claim 10:
11. An operator control and monitoring system for a process control system which controls a process in a technical plant, comprising:
at least one operator station client; and
at least two operator station servers which are interconnected via at least one communication means, each operator station server having a process image which includes process objects associated with the process;
wherein a graphical user interface is provided on the operator station client for displaying plant images with (block) symbols that are associated with the process objects and for process monitoring;
wherein a first component of the first operator station server is configured to determine whether a different operator station server of the process control system has failed,
wherein an alarm management component of the first operator station server is connected to the first component and is configured so as according to information regarding the failure of the different operator station server to check whether plant images which include process objects from the process image of the failed server are stored on the first operator station server and configured to check which plant images are consequently affected by the server failure and, in this case, trigger a configurable operator alarm which informs the operator that operator control of the affected plant image is limited; and
wherein a further component which manages an alarm status of plant images is connected to the alarm management component and is configured to update, in the process image, a tag of the alarm status of the affected plant image and to bring about via a visualization service that, in conjunction with the affected plant image, the operator alarm is displayed on the graphical user interface of the operator station client.
