Process Control System with an Engineering System, an Operator System and an Archive System

A process control system comprising:

• an engineering system for a project configuration of hardware and software components of the process control system;
• an operator system including a runtime component for operator control and monitoring of a technical process;
• and
• an archive system for archiving project configuration inputs of the engineering system and for archiving operator inputs in the operator system;
• wherein the engineering system includes a runtime component for storing engineering messages corresponding to the project configuration inputs, the runtime component of the engineering system being time-synchronized with the runtime component of the operator system;
• wherein operator messages corresponding with the operator inputs are entered in a runtime component of the operator system;
• and
• wherein the engineering system and the operator system each include an access component for writing their respective messages into the archive system and for reading out engineering and operator messages stored in the archive system.
