Realtime process history server
First Claim
1. Realtime process history server for use in a process control system for operating and monitoring a technical process or a technical installation, the realtime process history server comprising:
- a distributed control system (DCS) history server having realtime capability; and
a report server;
wherein the DCS history server is configured to receive and process data which is captured from the technical installation or the technical process, or which is input at operator workstations of the process control system and to store the received process data in a data storage under a realtime condition;
wherein the report server is configured to accept queries from both clients of a process information management system (PIMS) and from the operator workstations of the process control system, to hold said queries in a report queue and to service said queries consecutively by accessing said data stored in the DCS history server.

Abstract
The disclosure relates to a realtime process history server for use in a process control system comprising a process information management system (PIMS) and one or more distributed processing systems (distributed control systems DCS, 14.1 to 14.n). The realtime process history server features a combined PIMS/DCS server and a report server and is set up such that, by means of the report server, both clients and operator workstations of the DCS systems (14.1 to 14.n) have concurrent access under realtime conditions to the PIMS/DCS server and process history data which is stored therein.
