Control system for a technical installation with trend curve diagram

A control system of a technical installation, comprising:

• an operator station client;
• at least one operator station server including a visualization service for outputting image information to the operator station client and at least two object models of technical objects of the technical installation stored within the at least one operator station server, said technical objects underlying the at least two object models;
• wherein the at least one operator station server is configured to automatically generate an XY trend diagram with an operating point visualized in the generated XY trend diagram from a first measurement value associated with a first technical object and a second measurement value associated with a second technical object;
• and
• wherein the at least one operator station server is further configured to transmit the generated XY trend diagram with the operating point to the operator station client via the visualization service;
• wherein at least one of (i) the generated XY trend diagram and (ii) the operating point has a reference to at least one object model of the object models;
• wherein the generated operating point is influenceable by the technical object underlying the referenced object model;
• and
• wherein an operator of the operator station client is visually presented with the at least one referenced object model via the visualization service when selecting the generated operating point in the generated XY trend diagram.
