Networked intelligent motor-control systems

The integration of intelligent devices, device-level networks and software into motor control systems can deliver improved diagnostics, early warnings for increased system reliability, design flexibility and simplified wiring. Remote access to motor control information also affords an opportunity for reduced exposure to hazardous voltages and improved personnel safety during startup and troubleshooting. This article explores the communication cable requirements, intelligent devices and software required to integrate these new technologies into motor control systems. It also reviews the issues, changes in thinking and advantages that were found during the installation and startup of a plant system.
