Control System and Control Panel Upgrade for a Centrifuge (English)
Abstract [sv]

Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar.          

Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer.                

Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde. Vid driftstoppet testades sedan centrifugen både manuellt och med det automatiska programmet. Styrsystemet fungerade som förväntat och operatörspanelen behövde enbart några små justeringar för att få den så optimal som möjligt.

Abstract [en]

This thesis work is about upgrading a control system and a control panel for a centrifuge at a chemical plant. The purpose with this project is to be able to run the centrifuge in a more automatic approach and to increase the availability for accessory parts.           

The centrifuges older control system from Siemens has been replaced by a newer Siemens system and the former control panel from Siemens has been replaced by a Beijer Electronic E1070 control panel. The control system has been programmed in Siemens Simatic Step7 and the control panel has been programmed in Beijer Electronic E-designer.               

When the programming was done, there was some testing of the communication between the control system and the control panel before it was connected with the remaining system. During the closedown the centrifuge was tested both manually and with the automatic program. The control system worked properly and the control panel did only need some small modifications to be as optimal as possible.
