DESIGN AND IMPLEMENTATION OF PLC NETWORK SYSTEM USING OPNET MODULATOR.

This proposed design explains the methodology of PLC network control system for Industrial application. The programmable logic controller (PLC) is widely used for controlling and monitoring machinery on factory assembly lines, such as controlling upon the process of factory, temperature monitoring, remote maintenance, and factory automation, etc. The PLC network in this paper implemented using OPNET Modeler 14.5 for two schemas Ethernet and Wireless, using EXM-WIFI PLC to evaluate the performance of network such as delay, throughput, network load, and File download response time. OPNET Modeler 14.5 give good assumption on behavior of Ethernet and Wireless network
