Real-Time I/O Performance Metrics and Tests for Industrial Ethernet
James D. Gilsinn · 2004
Real-time input/output (I/O) communication over Ethernet is still fairly new in the industrial environment. There are many questions about the reliability and performance that have to be answered before industrial Ethernet can be utilized in most manufacturing plants. Similar questions are being asked in the information technology (IT) environment now that real-time communications are being used more heavily in such applications as real-time broadcasts and voice over the Internet Protocol (VoIP). Performance metrics and tests for IT infrastructure equipment have been used for many years, but now with real-time communications being used more, users are asking whether their desktop, laptop, or palm computer can handle the performance requirements of these network intensive applications. These same questions can be asked of industrial equipment as well. Can a Programmable Logic
