Abstract
Programmable Logic Controller (PLC) plays an important role in the automation process in the manufacturing industries. Typically, more than one type of PLC is used in a complete manufacturing automation process. Supervisory and control of every process in a manufacturing process are needed in modern industries to ensure a smooth and efficient manufacturing production process. Interoperability standard is needed to achieve the communication between the PLCs in the field layers with the upper supervisory level. OPC-UA is a platform independently interoperability standard for the open source controller and devices. The objectives of this report are to determine the function of client-server in OPC-UA implementation, to establish the architecture of OPC-UA for vertical communication between PLC and Upper-level controller devices or the SCADA system using KEPServerEX OPC-UA server, and to analyze the performance of OPC-UA in the communication. A simple OPC-UA server and client had been developed to visualize the working rinciple of OPC-UA client-server by using Node.js. The server is also connected to the UaExpert OPC-UA client to testing and verify the developed server. Vertical communication between the Omron CP1E PLC and Ignition SCADA system through KEPServerEX OPC-UA server with the Omron Fins Ethernet connection had been established and presented. The data of the PLC in the communication also being observed using UaExpert OPC-UA client.Experiments had been set-up to analyze the performance of OPC-UA architecture in communication by measuring the average time taken to complete the READ/WRITE instruction to the data tags under different hardware specification and security profile configuration by using the performance tools of UaExpert OPC-UA client.
