Connection siemens PLC (programmable logic control) to labview using OPC (ole for process control)

摘要

The project is to enable the Siemens PLC (Programmable Logic Control) S7-300 toudcommunicate with the Lab VIEW. The communication between S7-300 and Lab VIEW isudvia OPC (OLE for Process Control). Development of OPC using SIMA TIC NET OPCudServer. OPC is industry standard provides real plug-and-play software technology forudprocess control and factory automation. OPC integrate software and hardware acrossudspectrum of vendors easily. Visualization of Festo Didactic process developed usingudLab VIEW. Festo Didactic is small system which consist actuators and sensors . Theudprocess of Festo is to make hole for three different material red plastic, black plastic andudmetal. PROFIBUS is a medium to transfer data from PLC to Lab VIEW or Lab VIEW toudPLC.
