Using the OPC standard in order to integrate manufacturing management subsystem modules at integrated management information system

The article presents the usage of OPC standard on all levels of integration of manufacturing management subsystem at the integrated management information system. The structure of manufacturing management subsystem, with taking into consideration MES, SCADA and PLC systems, is presented in the first part of the article. Next, the most often used technological standards of integration on system and application levels are characterized. The final part of the article presents using OPC standard, with taking into particular consideration the specification of OPC Unified Architecture, in order to integrate manufacturing management subsystem on the system, application and business process level. This integration allows the data flow in real time to all subsystems of integrated management information system, what has a significant impact on the efficiency of the functioning of an enterprise.
