When revamping the oil gathering station Sergeevka (Bashneft), it was decided to introduce a state-of-the-art process control system with a user-friendly human-machine interface (HMI). The NPF Intek specialists were assigned to do the job.

The developed system comprises several centralized data acquisition and control stations, each is equipped with industrial computers (Advantech) which are Ethernet networked and used as servers, controllers and operator stations. The servers and data acquisition and control devices which are represented by the isolated input/output modules from Fastwel and Advantech as well as the intrinsically safe modules from Pepperl+Fuchs Elcon are housed in the Schroff cabinets.
The data from the flow meters are collected by a Mega controller designed by NPF Intek. It is connected to one of the three operator stations. The operator stations are desktop industrial computers and are designed to display the state of a facility, view the historical data and send the control commands.

When designing the network, the Hirschmann switches and transceivers as well as a Belden armored fiber-optic cable were used. One of the computers plays the role of a gateway and serves for the isolation of the process and general networks. This eliminates the possibility of an unauthorized access to the control computers, and at the same time, allows the remote users of the general network to view, via Internet Explorer, the real-time screens containing the current values of the process variables. Web server Iconics (WebHMI) working with GENESIS32 SCADA delivers Web pages to users. Based on this software, the user interface and the data processing and structurization functions were implemented in the developed system. The input/output boards are polled by the OPC-servers. The data from all the servers are collected in DataWorX32 where they are grouped by types and objects. The signals are then processed, archived (TrendWorX32), analyzed as to an emergency occurrence (AlarmWorX32) and animated displayed with the three detailing levels (GraphWorX32).The control and alarm functions as well as some calculations are implemented in the software developed by NPF Intek. Such software is installed on the servers.

Here are the key benefits offered by the system based on the industrial computers and GENESIS32 as compared with the widely used systems of the distributed controllers:

· ability to implement any complex control software due to the powerful resources of the industrial computers;
· the single tool for development, configuration and run;
· possibility to operate from any computer of the system.

In general, the system is flexible, extendable and very efficient. This has been achieved, in many ways, due to the vast capabilities of GENESIS32.
