1. An operator station server of a control system of a process engineering plant, the server comprising:
a computer-implemented process image comprising, at runtime of the process engineering plant, a first computer-implemented process object, a second computer-implemented process object and further computer-implemented process objects, which are each assigned to a technical object of the process engineering plant and are operatively connected to the technical object; and
a visualization service which is configured to transmit a symbolic system image to an operator station client for visualization, and configured to display block symbols generated from the first process object and the second process object in the system image;
wherein the first process object includes a structured and direction-oriented reference to the second process object, the direction-oriented reference comprising values derived from Continuous Functional Chart (CFC) plans during an engineering phase and loaded into configurations of the operator station server;
wherein the visualization service is configured to utilize the structured and direction-oriented reference to determine, via a first software component of the visualization service, a dependency of block symbols generated from the first process object and the second process object in the symbolic system image to derive a process engineering string for the system image;
wherein the visualization service is further configured to also include further process objects for the derivation of the process engineering string, of which no block symbols are displayed in the system image, system images in which the further process objects are present being determined for the further process objects; and
wherein the visualization service is further configured to calculate and update alarms for all block symbols and, with the determined system images and alarms at runtime, configured to create image change buttons in the currently opened system image so as to navigate from system image to system image along the derived process engineering string.
