HART AT THE SPEED OF ETHERNET
Ethernet networks have been pervasive in office environments for decades. But in process facilities, 2-wire 4-20mA wiring has been the norm. FieldComm Group developed HART-IP in 2012 to allow users to take advantage of available Ethernet infrastructure at Level 2 and Level 3 of the plant network. Today, mutiplexers, WirelessHART gateways and safety systems encapsulate 4-20mA HART data in Internet Protocol (IP) packets for high speed delivery to plant systems including asset managers and analytics.
The recent introduction of a 2-wired, powered, ethernet enabled physical layer, Ethernet-APL, creates an opportunity to bring high-speed HART-IP enabled instrumentation to the field level (Level 1). As operators and controls engineers grow accustomed to using high-speed ethernet enabled field instrumentation, HART-IP provides the familiarity of HART software over a state of the art communications and control infrastructure.
The video in this section was presented during the ACHEMA Pulse 2021 virtual event. It provides a brief history and overview of HART-IP technology, as well as a description of 2-wire Ethernet-APL technology. HART-IP and Ethernet-APL offer a great solution for obtaining the benefits of higher speed communication while maintaining all the software and work processes that are already familiar to end users.
