Software Support for PLC Automation Systems
Kříž, Karel ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This thesis mainly deals with the study of communication protocols between process control systems of company Siemens and their superstructural systems (SCADA/HMI) the Ethernet interface. This is a management systems, which are mainly used by Aucon s.r.o. in practice. It also deals with OPC servers, and their use with client applications. Emphasis is placed on the theoretical analysis of certain types of inter-processcommunication in Windows. From the simple one to the model COM, which is the basis of the OPC technology. Practical part realize implementation of a simple programming interface, providing communications with equipment Siemens Simatic S7. This is realized by C++ with using WinSock2 a IPHlpApi libraries. This interface can be used at programming client application.
