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.
HART-IP® and Ethernet-APL Explained
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.
This technical paper (20 pages) provides a high-level introduction to the mandatory security requirements provided by HART-IP servers/devices. It will benefit both users evaluating HART-IP or planning their deployment. It is also a good place to start if you are a device designer or thinking about developing a HART-IP product.
