Problems solved by technology

[0011] A disadvantageous characteristic of a system with a DCS proprietary database is that it cannot be flexible, or can only change configurations online within certain limits, and it cannot or can only change the configuration within a very short time interval. The data output to the office area can only realize the basic special API, trend chart and chart for the DCS client, the rewriting of historical records can only be very limited, and most of the experimental values ​​cannot be input at all

Embodiment Construction

[0020] An example application of the real-time process historian server 13 according to the invention is shown in FIG. 1 . It can be seen from the figure that the real-time-process historian-server 13 can be installed close to the midpoint between the typical PIMS level and the operation and monitoring level. It can be used simply and flexibly for installations 1, 2 and 5 on two levels. Several DCS systems 14 . All mentioned data transmission systems 9 , 15 and 16 can be, for example, bus systems or redundant standard networks. The process information obtained from the technical equipment or process via the DCS systems 14.1 to 14.n or entered into the operator's workstation 2 is transmitted to the real-time-process history-server 13 via the second data transmission device 15, and on this server Stored in the combined PIMS / DCS server 12.

[0021] Reporting queries from clients 1, 5 at the PIMS level and from operator workstations 2 at the monitoring and operations level (B&B...

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.

Description

technical field [0001] The invention relates to a real-time-process historian-server. Such a server is suitable for use as a so-called historian server in systems for operating and monitoring technical processes or technical installations. Among them, the historical record server is used as the real-time data basis for displaying operation trends. The real-time-process history-server is also suitable for providing and managing process information data for enterprise management. Systems for providing and managing process information data are also referred to as plant or process information management systems, or PIMS for short, and are usually installed in the upper layer of a process control system. It establishes the data foundation for ongoing reporting and detailed analysis that is typically implemented in a corporate office environment. Background technique [0002] With the gradual increase of process information data obtained over the years by means of equipment or ...
