Abstract

See full text

A process control input/output (I/O) device provides traditional I/O support with direct physical layers or interfaces associated with traditional process control communication protocols while at the same time supporting an advanced physical layer or other IP based physical layer and the communication protocols that run on top of them. In addition, the new I/O device is able to nest protocols inside of other protocols for use when protocols, such as safety protocols, require additional handshaking, confirmations, etc. Still further, the new I/O device includes hardware configurable capabilities that enable easy configuration of a process control system that uses multiple different physical layers, including those used by traditional process control protocols such as HART and FOUNDATION Fieldbus protocols, and more advanced physical layers, including those that are used by IP-based, Ethernet based, packet based and other types of advanced communication protocols.
