Using Switching Technology to Overcome Automation Protocol Clash

摘要

Plenty of automation pain has been caused by the lack of robust, reliable communications links between the PC-based world of IT network infrastructure and the sensors, actuators, and other process controls that manage the real-time factory-floor requirements of operational techno (OT). Industrial Ethernet systems require a high degree of determinism and reliability. In many factory automation applications, Ethernet has replaced legacy serial field bus connections because of its higher bandwidth and ability to link with enterprise networks. But Ethernet does not inherently have the deterministic response of field bus systems.
